Research on the capacity allocation of basin hydropower-photovoltaic-storage hybrid power generation system based on flexibility of hydropower and pumped storage power stations

The development and utilization of basin hydropower-photovoltaic-storage integrated energy system aim to smooth out the fluctuation of new energy generation capacity with the regulating ability of hydropower and pumped-storage power station, thus promoting the large-scale consumption of new energy. For regions rich in water, wind, solar, and pumped-storage resources, the main problem is how to allocate a reasonable scale of photovoltaic and wind power projects according to the scale of regional hydropower and pumped-storage power stations and realize the integrated development of multi-energy complementary. In this paper, based on the complementary power output characteristics of cascaded hydropower stations and regional photovoltaic power stations, and the good energy storage regulation of pumped-storage power stations, a capacity optimization model of basin hydropower-photovoltaic-storage hybrid power generation system with the goal of economic optimization under multiple constraints is constructed. It was applied to the planning and construction of the clean energy base in the Tibet-Sichuan section upstream of the Jinsha River, and the combined operation of the hydropower-photovoltaic-storage hybrid power generation system was analyzed to verify its feasibility.

Advances and development of wind–solar hybrid renewable energy technologies for energy transition and sustainable future in India

While solar power projects are built on a continuous ground, wind power projects require scattered land, raising transmission costs and increasing the risk of land-related complications. Wind–solar hybrid (WSH) projects have been proposed to address these issues and accelerate installation. WSH power projects will create a well-defined area with sufficient infrastructure, including evacuation facilities, where the project’s risks can be reduced. The extensive coastline of India is endowed with high wind flow speed and plentiful solar power resources, creating an ideal environment for WSH projects to prosper while simultaneously improving grid stability and reliability. WSH plants guarantee higher transmission efficiency and cost-effectiveness than their stand-alone counterparts. As of 30.11.2021, 3.75 GW of WSH projects have been granted, with 0.148 GW of operational capacity and 1.7 GW of WSH projects in various bidding phases. In this paper, we discussed state-wise WSH potential, the key players in the WSH project, the National WSH, and the State WSH policy and amendments. Also, the WSH project’s physical progress and commercial details are covered. A feasibility study of the WSH plant is performed, and the primary design strategy for deploying WSH power facilities in India is discussed. It covers every step of this process, from design technique to choosing and evaluating potential locations for such hybrid projects, optimally placing wind turbines and solar panels, overall capacity mix for hybrid plants, and ultimately power evacuation optimization. Additionally, a brief study of the savings from these hybrid plants and the environmental, social, and governance standards which are necessary to implement these projects are provided. The potential challenges connected with WSH technologies are examined in depth, and potential solutions and mitigations for the challenges are provided. Designing a WSH for small-scale irrigation is provided along with the size and choice of wind and solar systems. Degradation of PV systems and carbon savings are included, along with some policy measures to boost the proportion of WSH in the entire power mix. In India, the development of large-scale WSH projects is still in its early stages, and more research is required to explore technical, commercial, and policy elements that influence project design. The policy suggestions for improvement of the WSH project are provided. The WSH project developers, potential investors, stakeholders, innovators, policymakers, manufacturers, designers, and researchers will benefit from the recommendations based on the review’s findings.

Effectiveness of an artificial intelligence-based system to curtail wind turbines to reduce eagle collisions.

Operating wind-power projects often includes protecting volant wildlife. One method for doing this uses an automated system to detect, identify (through use of artificial intelligence; AI), track animals (targets) and curtail turbines when risk of a collision is high. However, assessments of the effectiveness, in terms of identification accuracy and subsequent turbine curtailment of such systems are lacking. Over 1 year, we assessed such an automated system installed at a wind project in California, USA to determine its identification accuracy and rates at which "virtual" curtailments were ordered (without slowing turbines), for eagles (intended targets) and non-eagle targets. The system correctly identified 77% of eagles and 85% of non-eagles. Curtailment orders occurred 6 times more frequently for non-eagle targets (5,439) than for eagle targets (850). Greater abundance of common ravens that were misidentified as eagles influenced the effectiveness of the system by greatly increasing unintended curtailment orders. The balance between costs (price of the IdentiFlight system, reduced energy generation, turbine wear and maintenance) and benefits (reduced collisions between intended target species and turbines) may depend upon the biological setting, speed at which operators can curtail turbines, and the objectives of the operator when considering the IdentiFlight system.

Effect of Chinese Currency Appreciation on Investments in Renewable Energy Projects in Countries along the Belt and Road

Foreign investment in renewable energy generation projects is a critical part of the Belt and Road Initiative. Under the background of the market economy, the electric energy will participate in power market competition among the countries along the line, and the sales revenue will be settled in the local currency. The exchange rate of the countries along the Belt and Road fluctuates frequently and widely, thereby posing significant risks to the investment income of the projects. To address this problem, this paper proposes the concept of Ek as the effective exchange rate expressed by the on-grid price, investment cost per kilowatt electricity generation equipment, and annual operating cost rate of unit power generation capacity. Moreover, this paper presents a model of power generation cost, income, and earning expressed by the real exchange rate. The flexibility formula of the fluctuation of power generation cost, income, profit, and internal rate of return relative(IRR) to Ek is derived, and the effect of exchange rate level and fluctuation on projects is analyzed. With the wind power projects invested by China in Pakistan taken as an example, the trend during the entire life cycle is calculated. The changes in net profit rate, IRR, and levelized cost of energy (LCOE) are calculated under Chinese currency appreciation of 10%, 20%, and 35% and 5% and 10% reduction of investment cost per unit. As the Chinese currency appreciates and the project IRR declines significantly, LCOE decreases slightly, but this decrease is not sufficient to compensate for the losses caused by the decline in IRR. The following effective measures are proposed to deal with the exchange rate fluctuation of foreign renewable energy generation projects: building energy Internet, reducing project cost, and using Chinese currency as the settlement currency. In this paper, a solution is provided for investments in renewable energy projects in regions where exchange rates fluctuate greatly.

However, the contradiction between the large-scale construction of wind power and ecological protection is becoming increasingly prominent. It is urgent to clarify the impact of wind power projects on the ecological environment, especially on potential ecological corridors and regional ecological security patterns. This study took Pingtan as the study area, and applied Morphological Spatial Pattern Analysis, Minimal Cumulative Resistance and gravity models to identify importantly ecological source sites and potential corridors. In addition, the impacts of wind power projects on the connectivity, pathways and importance of ecological corridors were assessed. The results showed that: (1) the ecological sources were mainly located in forest parks and scenic spots with high ecological value. The fragmentation of ecological source was increasing due to the impact of wind power projects. The percentage of ecological core areas decreased from 79.53% to 76.64%. (2) Wind power projects have reduced ecological corridor accessibility, significantly changed the alignment and length of ecological corridors, and greatly increased the spatial resistance for biological migration. (3) The wind power project weakened the correlation between ecological source sites. Both important and secondary corridors were reduced by six and the ecological corridors of high importance completely avoided the location of the wind power project. After the construction of wind power projects, the ecological network became less fluid, more homogeneous, and less effective overall. This study not only provided a reference for biodiversity conservation and ecological security patterns in the ecologically fragile areas around wind power projects, but also provided important methodological support for wind power project siting and environmental quality assessment. 参考文献 相似文献 引证文献

Evaluating the role of renewable energy investment resources and green finance on the economic performance: Evidence from OECD economies

Recently, economic performance is considered as the global requirement because of the environmental uncertainty and energy resources issues that gained the attention of recent literature and governments or policymakers. Therefore, the primary goal of the present study is to examine the impact of renewable energy investment as well as the investment in different resources of renewable energy such as geothermal, solar, bio energy, hydropower and wind power project and green finance on the economic performance of organization for economic co-operation and development (OECD) economics. The authors have taken the secondary data from 2001 to 2019 that are extracted from the international renewable energy agency (IRENA), global green finance index (GGFI) and world development indicators (WDI). The current article has used the generalized methods of moment (GMM) and fixed-effect (FEM) model to explore the nexus among the said variables. The results indicate that renewable energy investment resources and green finance have significant and positive effect on the economic performance of selected economics. This study provides help to the future researchers while exploring this area and also guides the policy makers regarding making the policies for the economic performance and renewable energy resources investment.

Evaluation of Wind Energy Potential in Omu Aran, Nigeria Using Weibull and Rayleigh Models

The depletion of resources and emission of hazardous gases have been identified with conventional sources of energy. The negative influence of conventional sources of energy on the environment necessitates the call for the use of renewable and sustainable energy sources, such as wind. Wind power is one of the available renewable energy sources in Nigeria with huge potential that can be tapped in order to contribute to its energy mix. Wind energy utilization in Nigeria is poor because the available data in all six geopolitical political regions for system design have not been fully analysed and implemented. Wind energy projects are liable to failure if proper analysis is not done. Therefore, before any location could be considered suitable or unsuitable for wind power generation, the power density must be determined using the standard approach. This study, therefore evaluated the wind energy potential of Omu Aran, Nigeria using Weibull and Rayleigh models. Five years data collected from the metrological station of the Landmark University on Lat. 8.14 oN; Long. 5.10 oE were processed and analysed in Matlab computer software using a code developed for two statistical modelling methods (Weibull and Rayleigh). The actual mean yearly wind speed of 3.964 m/s for Kwara falls in the low wind speed. Although, the power density for hours of the day, months, and seasonal variation ranged from 24 to 141 W/m2. More than 50% of the power density for daily hours was less than 100 W/m2 which indicated that Omu Aran, Nigeria belongs to class 1. The coefficient of efficiency (COE) for Weibull probability distribution ranged from 39.95 to 94.9 while the coefficient of determination (COD) R2 ranged from 0.66 to 0.98. This range of performance values for the Weibull model, when compared to the Rayleigh model, were within the acceptable limits for prediction accuracy, hence the Weibull probability distribution function can be used for the preliminary design of wind power plants for Kwara State, Nigeria. Therefore, it would help the relevant stakeholders in wind power project investment to make the appropriate decision.

Social impact assessment of wind power generation. An innovative method for decision making processes

This paper explores the social impact for population in the energy sector combining LCA and SIA (social impact assessment). As case study, a new 66 MW wind power plant under development in the countryside of Southern Sardinia has been considered. The innovative method, based on the analysis of the context, aims to empirically analyze some selected sustainability indicators. The proposed method starts from a detailed analysis of the wind power project, with particular reference to the plant site characteristics, technical features of the wind farm, opinions of the stakeholders, environmental and social impacts and expected economic benefits. The acquired data are validated with a Severity statistical method that identifies the KPIs. The indicators are classified into general categories of damage Human life, Safety guarantee, Social resources, Public participation and analyzed through a combined SIA-LCA method to identify indicators damage weights.This work shows the importance of putting together indicators already explored in the environmental field such as Human health, Ecosystem quality, Resource, Climate Change and as social indicators Renewable Energy with Noise, Visual Impact, Shadow Flichers, the perceptions of the local community.

Wind farms in contested landscapes: Procedural and scale gaps of wind power facility constructions in Japan

The legal system for renewable energy in Japan, Feed-in Tariff system, was deregulated in 2021 by the central government to reflect the international calls to reduce greenhouse gas emissions. However, this sudden change has raised concerns about social, environmental, and long-term economic sustainability. Thus, we conducted a state-of-the-art review of legal and policy frameworks of wind power projects in Japan and discussed the multi-layered structure at national- and municipal-level ordinances. By doing so, several gaps are highlighted. First, there are procedural gaps that business operators can de facto bypass by checking the environmental procedures. Second, there are issues at the scale (national or local), where the decisions are met. For example, while the overall framework is decided at the national level, the most contentious issues of the location of wind power facilities are left at the local level, where residents, municipalities, and developers are burdened to solve these issues. Third, in the current legal system, environmental impacts on popular natural landscapes are not taken into consideration. In the face of deregulation and concerns about multiple factors, there has been an increase in the number of municipalities opposing the construction of wind farms. Finally, existing legal cases related to wind power projects are provided to illustrate changes and disputes at different sites across Japan. These cases demonstrated how landscape elements (e.g. biodiversity) can be vital for wind power project development in Japan.

Study on AC interference law of high voltage AC cable to submarine pipeline and safe distance

AbstractIn recent years, due to the large‐scale construction of wind power and shore power projects, the amount of submarine high‐voltage AC cables has been increasing year by year, and they often form a “common corridor” in parallel with adjacent submarine pipelines, resulting in AC interference on pipelines. A lot of research has been carried out on the AC interference law of buried pipelines onshore. However, there is a lack of discussion on the AC interference suffered by submarine pipelines from high‐voltage AC cables. How to understand the AC interference law of high‐voltage AC cables to submarine pipelines and determining the safe distance has become an urgent demand in practical production. Based on this, this paper established a calculation model for AC interference suffered by submarine pipelines from high‐voltage AC cables on through CDGES software. Through simulation calculation, the influence laws of many factors such as parallel distance between AC cables and pipelines, parallel length, cable load current, anticorrosive coating resistivity, and longitudinal pipeline resistance per unit length on AC interference parameters of pipelines were investigated. It was found that the degree of AC interference increases with the increase of the anticorrosive coating resistivity, the load current, and the longitudinal pipeline resistance per unit length, as well as the decrease of the parallel interval. However, with the increase of the parallel length, the AC interference voltage and current density of the pipeline increase firstly, then decrease, and at the end remains unchanged, and it was found that there existed the parallel length with the maximum AC interference and the saturation parallel length with unchanged AC interference. Based on the principles of electromagnetic induction and AC circuits, the main reasons for the parallel length with maximum AC interference and the saturation parallel length were analyzed in this paper. The safe distances avoiding AC corrosion under different parallel lengths and load currents were discussed, which can provide a reference for the evaluation of AC interference of submarine pipelines and the selection of submarine routing.

Small hydropower, large obstacle? Exploring land use conflict, Indigenous opposition and acceptance in the Norwegian Arctic

In this study, we explore Indigenous energy opposition to and acceptance of small hydropower development. In Sápmi (i.e., the traditional homeland of the Indigenous Sámi people), land development poses a major threat to the cultural and material needs of the Sámi people through the loss of pastures essential to Sámi reindeer herding. In contrast to large-scale renewable energy projects such as hydropower, power line and wind power projects, the impact of small hydropower (SHP) development on Indigenous land use has received relatively little attention. We mapped Indigenous opposition to and acceptance of new SHP development in a key region for Sámi reindeer herding in northern Norway from 2010 to 2018. Our results show how the proliferation of SHPs on reindeer pastures caused concern among Sámi reindeer owners and their representatives, who devoted considerable resources to participating in and opposing new SHPs through public hearing processes. In many cases, other actors, such as environmental interests, also opposed. Nevertheless, most cases opposed by Indigenous representatives were licensed (59 %). Considering our results and given the potential for and interest in expanding renewable energy, Indigenous opposition to SHP development warrants greater attention. Our approach provides a larger-scale, larger-N, quantitative view of opposition to SHP development that can complement more qualitative and in-depth approaches.

A hybrid probabilistic linguistic term set decision-making evaluation method and its application in the site selection of offshore wind power station

In the context of carbon neutrality, China vigorously develops clean energy and renewable energy. As a result, offshore wind power projects have grown rapidly. The success of offshore wind power projects depends on the location of offshore wind power station(OWPS), and this paper aims to develop a hybrid decision-making framework to address the location of offshore wind power stations. Firstly, a comprehensive evaluation attribute system of offshore wind power station site selection is innovatively constructed, including wind resources, construction conditions, economy, environment and risks. Secondly, probabilistic linguistic term set(PLTS) is used to describe uncertain information, which improves the reliability of decision information. Thirdly, The Best-worst method (BWM) based on probabilistic language term sets determines the weights of attributes, which ensures the accuracy of the attribute weight. Finally, an extended TODIM (an acronym in Portuguese of Interactive and Multicriteria Decision Making) method is proposed to rank the alternatives. The proposed method is applied to the location selection of offshore wind power station in Jiangsu Province, China. Through sensitivity analysis and comparative analysis, it is verified that the proposed model has good stability and applicability.

Windmill Global Sourcing in an Initiative Using a Spherical Fuzzy Multiple-Criteria Decision Prototype

The government of Karnataka has resolved to promote and employ an increasing number of alternative fuels, particularly, wind energy. Selecting a windmill supplier is a key decision when developing a wind energy project, and investors must evaluate various qualitative and quantitative variables that interact symmetrically to discover the best source. As a result, a multi-criteria decision-making procedure is applied to choose a wind turbine provider for wind power projects. A variety of approaches have been used to address this judgment process, some of which were predicated on the use of multi-criteria judgment techniques alone or in conjunction with some different multiple-criteria decision approaches. In this study, the researchers advocated selecting windmill producers for geothermal power generation using a judgment method based on a spherical fuzzy system. After the analyses of the last stage of this research, turbine manufacturers for installations could be suggested. The purpose of this research was to develop a fuzzy multi-criteria foundation for choosing appropriate rotor makers for electricity production. Specialists can utilize the conclusions of this study to choose an appropriate windmill operator in other states, including for green initiatives of a similar nature.

Converting Offshore Oil and Gas Infrastructures into Renewable Energy Generation Plants: An Economic and Technical Analysis of the Decommissioning Delay in the Brazilian Case

The offshore harnessing of oil and gas resources is made possible by massive infrastructures installed at sea. At the end-of-life stage, in the absence of new uses for offshore installations, decommissioning proceedings usually take place, requiring the removal and final disposal of all materials. In Brazilian waters, decommissioning is hampered by high costs. The offshore wind-power sector has arisen as a new clean power source, in line with worldwide de-carbonization initiatives. In this context, we propose an innovative approach suggesting offshore wind power projects as an alternative to the removal and final disposal of infrastructures, a potential solution to Brazilian offshore decommissioning. In this article we report on the assessment of structures at the end of their lifecycle along with decommissioning cost estimation. Then, we explore wind turbine installation viability along the Brazilian coast and estimate the levelized cost of energy for each wind turbine. Finally, the results allow us to conduct a critical analysis of customary decommissioning versus the repurposing of infrastructures as offshore wind power project sites in two scenarios involving site repurposing. Our main results indicate that the CapEx discount rate of wind power projects offsetting decommissioning is considerable, as are the benefits of delaying decommissioning in terms of reduced carbon emissions and the social effects of increased local employment rates, through the repurposing of offshore oil and gas infrastructures.

PROFITABILITY OF INCENTIVE PURCHASE PRICES FOR WIND FARM PROJECTS IN CROATIA

In 2007 the Croatian energy legislation underwent a series of changes. Along with the opening of the electricity market to all legal entities, on 1 July 2007 a package of five bylaws on the incentives to electricity generation from renewable energy resources entered into force. The incentive method Croatia has opted for are feed-in tariffs, the widest-spread and currently most successful method in the European Union. In Croatia a massive venture capital interest in renewables is recently manifest, especially wind power projects. This raises a question about the real profitability of such projects and whether or not the incentive puchase price is high enough to make the wind power projects viable. The present work analyses a generic wind power plant project, installed power 25 MW (the reasons why this rating has been chosen are given later on), by using RETScreen International Software, developed in Canada and used throughout the world. The introductory part, which describes the current situation in Croatia regarding renewables, is followed by a brief overview of newly introduced bylaws aimed to provide incentives for electricity generation from renewables. The works explains in detail the input of all relevant technical, economic and financial parameters and shows the results of modelling a wind power plant with capacity factors of 18 %, 20 %, 22 %, 25 %, 27 % and 30 % by using RETScreen International Software. A detailed susceptibility and risk analysis is given for a wind power plant with the capacity factor of 25%, followed by a conclusion.

Statnett SF v. Sør-Fosen Sijte (Sup. Ct. Nor.)

On October 11, 2021, the Supreme Court of Norway, sitting as a Grand Chamber, had to decide in three interconnected cases (HR-2021-1975-S) whether the construction of certain wind power plants, which will form part of the largest onshore wind power project in Europe, in a particular rural area interfered with (Sami) reindeer herders’ rights to enjoy their own culture according to Article 27 of the International Covenant on Civil and Political Rights (ICCPR). The case, which had been initiated long before Russia's war of aggression against Ukraine and concomitant spiking energy prices—which might have added an extra dimension to the underlying, countervailing issues—pits efforts to increasingly produce “green,” renewable energy and the minority rights of a particular cultural group against each other. Taking the peculiar requirements of reindeer husbandry, the need for safe winter pastures, and the specific geographical conditions of the locus delicti into account, the Court concluded that the windfarms would have a substantial negative effect on the reindeer herders’ possibility to enjoy their own culture, which, in the absence of satisfactory remedy measures, threatened the very existence of reindeer husbandry on Fosen, and therefore found a violation of Article 27, ICCPR.

Comprehensive Objective Optimization Analysis of Construction Projects under Multiobjective Particle Swarm Optimization

Due to the future development of the construction industry towards the sustainable development direction of green, ecology, and safety in the future, the ultimate goal requirement of engineering projects will be higher, and the investment traditional objectives, time limit, and quality cannot meet the requirements of comprehensive management objectives. Therefore, safety and environmental management were added in this paper based on traditional management objectives from the perspective of the project owners, the relationship between objectives was analyzed, and an equilibrium optimization model of objectives was constructed. A series of Pareto optimal solutions were obtained by using multiobjective particle swarm optimization (MOPSO). Then, the best scheme was selected from the series solutions by using the efficiency coefficient method according to the specific requirements of project management. Finally, taking the objective comprehensive optimization management of a wind power project in Sichuan province as an example, 1000 paths are run by using a multitarget particle swarm algorithm, and the mean and standard deviation of the 1000 paths are calculated. The rationality of the model and the practicability of the multiobjective particle swarm optimization algorithm in the study of engineering project comprehensive optimization management were verified. It has realized the multiobjective optimization management of engineering projects and contributed to improving the quality of engineering management.

Contested renewable energy sites due to landscape and socio-ecological barriers: Comparison of wind and solar power installation cases in Japan

There has been an increasing effort to promote renewable energies as climate change mitigation measures in Japan. Yet, the installation of wind turbines and solar photovoltaic (PV) power plants is being contested in several parts of the country. There is a need to understand these oppositions to reduce the number of delayed projects or overcome future barriers. Thus, in this study, we investigated cases of opposition movements and legal proceedings against wind and solar PV power development. Results indicated that landscape elements and socio-ecological factors motivate local oppositions. For instance, there were cases filed due to landscape view obstruction caused by wind turbines and solar panels. In terms of socio-ecological barriers, examples of cases scrutinized showed opposition caused by the potential impact on recreational activities such as climbing and hiking trails. Additionally, we observed that there were differences in the scope and scale of opposition movements and legal proceedings between wind and solar PV power projects. These differences were related to the scale (project size) and duration (construction to operation) of the project coupled with the renewable energy-related legal system changes in Japan. We observed that the overall legislative framework is frequently designed at the national level while challenges in project site selection are dealt with at the municipal- and prefectural-level. The findings of this study can help policymakers to revise and/or develop legal systems that minimize impacts on landscape and social elements while satisfying the demand for renewable energy transitions.
