Point of Common Connection Voltage Modulated Direct Power Control with Disturbance Observer to Increase in Renewable Energy Acceptance in Power System

In this paper, we present a disturbance observer-based point of common connection voltage-modulated direct power control (PCCVM-DPC) system, which increases the robustness of the PCCVM-DPC system. First, the mathematical analysis of the disturbances for the step-up transformer’s nonlinearity, the grid voltage harmonics, and the parameter uncertainties is presented. By analyzing the disturbance terms of the PCCVM-DPC system, we present the disturbance observer (DOB) for the PCCVM-DPC system. To assess the efficacy of our approach, we perform comparative studies of the PCCVM-DPC without DOB and PCCVM-DPC with DOB by constructing the simulation environment based on the commercial step-up transformer and ESS inverter datasheet. We have validated that the active and reactive power control performance of the PCCVM-DPC with DOB outperforms the PCCVM-DPC without DOB from the observation that the current total harmonic distortion reduced by more than 40% compared to the PCCVM-DPC without the DOB.

Shaping stable support: Leveraging digital feedback interventions to elicit socio-Political acceptance of renewable energy

In democratic countries, the success of energy policies hinges on citizens' support and their acceptance of policy outcomes. In this study, we develop a digital feedback intervention to prompt citizens with information that visualizes the geographical distribution of wind turbines and to evaluate the effects on socio-political acceptance. In an online experiment, we exposed 430 German citizens to a personalized digital feedback intervention and elicited their acceptance of renewable wind energy. The results are threefold: First, citizens' acceptance of renewable wind energy that results from digital feedback is lower than initially claimed. Second, citizens who meaningfully engage with the digital feedback intervention are more likely to revise their acceptance of wind energy. Third, and surprisingly, citizens’ ecological attitude and place attachment to their current residence had no significant effect on the extent to which they revised their acceptance of renewable wind energy. Our results demonstrate that digital feedback interventions can act as a “sensor” for socio-political acceptance. This contributes to informing citizens about energy policy outcomes and provides valuable insights for policymakers promoting a participatory democracy paradigm.

Concept and Modeling of Participation Opportunity for Large-Scale Renewable Energy Plants

Citizen participation in the energy transition is desirable for many reasons: it increases acceptance of renewable energies, fulfils the wish to make one's own contribution to the energy transition and generates relevant parts of the necessary capital for the transformation of the energy system. This paper presents a scalable participation concept for the German legal framework which allows citizens to invest in and partially consume electricity from large-scale renewable energy plants at the time of generation. The developed concept provides a method for direct financial involvement via a direct contract with local electricity suppliers and virtual self-consumption by matching demand with PV generation – without the need for property ownership or new subsidies. Different consumer types and participants shares of a large-scale PV plant are modelled and simulated for the years 2019-2021. The financial advantage of citizen participation depends on the type of energy generation plant, yearly (solar) yield, on the remuneration for the surplus energy quantity, on the electricity procurement costs, on the customer's energy consumption, on the amount, and time flexibility and others. This paper shows that all analysed consumer types have the potential to profit from the model every year, although simulations are dependent on variable annual factors and assume the energy supplier's short-term procurement. The approach’s scalability and organizational simplicity could expedite the development of local participatory projects and contribute significantly to Germany's energy transition.

Framing the Wind: Media Coverage of Offshore Wind in the Northeastern United States

ABSTRACT Media coverage shapes public acceptance of renewable energy, but how offshore wind is being communicated to the public, particularly in the United States, is understudied. This study investigates the framing approaches of media coverage of the first two large-scale offshore wind projects in the U.S. We find that most coverage is local, with media coverage increasing during debates around permitting, construction, and community impacts. Emphasis framing focused on economic, political, and environmental dimensions of offshore wind, but the framing differs significantly between the cases. Benefit frames focused on job creation, climate mitigation, and political leadership and collaboration. Risk frames focused on political conflict and lack of transparency, impacts on wildlife, and economic impacts on the fishing industry. These findings help contextualize the debates around offshore wind in the U.S., elucidating what dimensions are made most salient to the public and how project characteristics may drive media coverage.

Collaborative Planning of Energy Storage System Considering Peak Regulation Demand and Renewable Energy Integration

Abstract The capacity of renewable energy integrated into the grid is steadily expanding, necessitating strategic planning of energy storage systems (ESS). Such planning is pivotal not only for reducing peak load shaving but also for augmenting the grid’s capacity to accommodate renewable energy sources. In this manuscript, an ESS planning scheme considering peak regulation demand is proposed. The outer model of this scheme constitutes a multi-factor optimization model with the net income of ESS and the new renewable energy acceptance index. The inner model is an optimal dispatching model, which aims at minimizing the system peaking operation cost, optimizes the renewable energy acceptance of the system, and obtains the charging and discharging power and energy storage configuration capacity of the ESS. Finally, the improved IEEE-30 bus system is used for simulation, and the results verify the feasibility and effectiveness of the proposed method.

Social Acceptance of Innovative Water Technologies as a Development and Design Norm in North Cyprus

This paper addresses the necessary innovative methods for water production and harvesting as a design norm,especially in areas that are facing water shortages both now and in the long term, an example of which is NorthernCyprus Amidst projections forecasting that half of the global populace may confront water scarcity by 2025, and anestimated 700 million individuals could face displacement due to water scarcity by 2030, the imperative to diversifywater-sourcing mechanisms becomes paramount.

It synthesizes extant scholarship on water management in North Cyprus, focusing onparticipatory design methodologies and their ramifications on the societal embracement of novel water technologies.Environmental determinants such as climatic conditions and human factors such as social behavioral patterns andinfrastructure maintenance are factors that have a direct impact on the analysis of water management in multifaceteddimensions. In addition, attitudes, social norms, and perceived behavioral control are effective in social acceptance ofrenewable energy projects in general and, in this paper, innovative water projects. Participatory design in a specialway causes the community to participate receive support.

Community-developer collaboration and voluntary community benefits in Scotland: Are community benefits a gift or compensation?

Community benefits are a key strategy for promoting social acceptance of renewable energy and ensuring distributive fairness of the energy transition. However, they can sometimes damage rather than strengthen the relationship between communities and developers. This paper examines stakeholder submissions to The Scottish Government's Good Practice Principles on Community Benefits from Onshore Renewable Energy Developments (2019) consultation. Communities perceive community benefits as compensation and express concerns about their voluntary nature, while developers see them as benevolent gifts, worrying about their impact on project viability. As the guidelines are voluntary, community benefit arrangements rely on collaboration between developers and communities, but power imbalance and a lack of shared understanding can impede this collaboration. Inspired by governmentality literature, this study analyses stakeholder discourses to understand how issues are framed, solutions proposed, and rationalities guiding these discussions. Qualitative system dynamics modelling is used to provide a comprehensive view of challenges in the design of community benefit arrangements in Scotland, highlighting risks to the developer-community relationship and trust in the energy transition. The analysis suggests that making community benefit arrangements mandatory or rethinking them is essential to preserve this relationship and trust.

Influence of the DC frequency limit controller on the frequency characteristics of the multi-area asynchronous interconnected power grid with renewable energy integration

To systematically analyze the impact of the DC frequency limit controller (FLC) configuration scheme on the frequency characteristics of asynchronous interconnected power grids with renewable energy integration, a comprehensive frequency analysis model for three-area asynchronous interconnected power grids including the FLC is proposed. The model is based on the SFR model considering renewable energy integration and includes a simplified model of the DC FLC. A rigorous validation of the rationality and stability of the model is achieved through detailed mathematical calculations and pole-zero analysis. Taking the local power grids as an example, the established model is used to study the difference between single- and double-sided configuration of the DC FLC, the relationship between the increase in the renewable energy penetration rate and the frequency characteristics of each regional power grid, and the influence of DC FLC configuration on the maximum acceptance ratio of renewable energy. Through data comparison and theoretical analysis, the influence of FLC configuration on the frequency characteristics of each region of the asynchronous power grid under renewable energy integration is obtained. The results show that the configuration of a bilateral FLC on the DC line has more advantages in alleviating the complementary power disturbance at both ends and obvious limitations on the non-complementary power disturbance at both ends. Compared with the configuration of the bilateral FLC, the configuration of a unilateral FLC on the weak grid has a larger proportion of renewable energy acceptance. When the DC FLC power transmission capacity is sufficient, the weak grid and the adjacent two asynchronous grid DC tie lines are configured with a single-sided FLC, and the weak grid is theoretically connected to the renewable energy penetration rate of up to 100%.

How Do Instagram Messages Affect the Use of Renewable Energy? -- Applica-tion of an Extended Information Adoption Model

As social media can play an important role in creating awareness of the need to mitigate climate change and of the benefits of renewable energy (RE), we examined the influences of social media on attitudes to renewable energy, including intention to use it. This study is novel in two ways: it simultaneously considers message characteristics and message-receiver perceptions as factors influencing the acceptance of renewable energy; and it is also the first study to use an extended information adoption model to evaluate the impact of Instagram on information adoption and the intention to use renewable energy sources. Our questionnaire, based on the theory of information adoption, included items on attitude toward information and trust in Instagram, and was randomly distributed online among followers of renewable energy pages on Instagram. A total of 173 people completed the questionnaire. Structural equation modeling showed that quality of argument had a positive and direct effect on the perceived usefulness of information. Source credibility as a peripheral path also indirectly increased perceived usefulness by changing attitude toward information. Moreover, perceived usefulness had a direct impact on information adoption and increased information adoption through trust of the materials.

Can renewable energy work for rural societies? Exploring productive use, institutions, support systems, and trust for solar electricity in the Navajo Nation

Reliable electricity and water access remain major challenges in rural communities worldwide. Standalone renewable energy systems show promise in improving access, but successful long-term outcomes remain infrequent in practice. To achieve sustainable outcomes, planners and decision makers should place a greater emphasis on understanding community context to determine the technological and social appropriacy of renewable energy technology. This article investigates a case study of renewable energy systems in the Navajo Nation to develop an understanding of what technical and social considerations may be necessary. A qualitative exploratory data analysis approach is used to perform a comparative analysis of two programs that deployed solar home systems (SHS) and atmospheric water generation (AWG) systems to address electricity and water needs in the Nation, respectively. The findings reveal that renewable energy programs should critically evaluate four factors related to technological and procedural appropriacy. These four factors are (1) an understanding of the productive use of the technology in context, (2) the need to operate within extant institutional paradigms, (3) the capacity to develop and maintain a support network, and (4) the need for trust building. The findings indicate that productive use of renewable energy is determined by end-user application and its usefulness in the community’s rank order of priorities. It also demonstrates that social acceptance of renewable energy is affected by the willingness of programs to conform to existing institutional paradigms. This article refines and expands upon existing themes of social acceptance, making them more application oriented by focusing on the planning phase.

Evaluation of Renewable Energy Hosting Capacity of Grid with Multi-Infeed HVDC

Considering the impact of large-scale renewable energy access to a multi-infeed HVDC receiving-end system on its voltage stability and multi-infeed short circuit ratio, a renewable energy acceptance evaluation method based on an improved holomorphic embedding method is proposed. Firstly, to construct a model containing only an AC system, the DC inverter is simplified into an AC source model; secondly, the sigma index is used to judge the static voltage stability of the system bus and determine the access location of renewable energy, and sensitivity index is used to determine the scheme of replacing conventional units with renewable energy; then, with the voltage crossing the set range as the constraint condition, the analytical expression of each bus voltage obtained by the holomorphic embedding method is used to solve the maximum renewable energy capacity of the system; finally, under the maximum hosting scenario of renewable energy, verify the multi-infeed short circuit ratio at each DC drop point. The effectiveness of the proposed method is verified on an improved IEEE39-bus system.

A Combing Data-Driven and Model-Driven Methods for Renewable Energy Acceptance Capacity Assessment in Distribution Networks

To accurately improve the balanced new energy distribution network capacity assessment, this paper proposes a combined data-driven and model-driven renewable energy capacity assessment method for distribution networks. Firstly, the distribution generations (DG) output data are pre-processed to construct a scenario training sample set and extract seven types of DG daily output characteristics indicators. Secondly, a scenario generation model based on a conditional generation adversarial network is proposed to realize the coupling of scenario reduction and scenario generation based on K-means++ through daily output characteristics indicators. Finally, the optimization model based on hybrid positive linear programming is proposed for distributed power supply acceptance capacity evaluation of the distribution network with the objective of maximum DG access capacity and full consideration of voltage deviation, branch current, tidal current return, and other operational constraints. It is validated by IEEE 33-bus simulation. The simulation analysis shows that the proposed method can effectively quantify the DG capacity uncertainty compared with the traditional method, and the proposed method has higher computational accuracy and efficiency than the traditional method.

Clean Hydrogen Portfolio Standard 기반 Virtual Clean Hydrogen Plant 플랫폼 설계 및 운영 전략

In Korea, there are separate areas for renewable energy concentration and power load concentration. As both renewable energy and power demand increase, transmission constraints lead to saturation of renewable energy. This phenomenon has adverse effects on the benefits of Independent Power Producers (IPPs) and renewable energy acceptance. Policymakers and individual power generation operators must solve this essential problem. This paper proposes a new energy operation system that converts surplus energy generated by transmission constraints into hydrogen and supplies it to load-intensive areas. This system utilizes PV complexes in renewable energy-intensive areas through the Virtual Clean Hydrogen Plant (VCHP) platform. South Korea plans to introduce the Clean Hydrogen Portfolio Standard (CHPS), which provides a fixed premium (FP) to power generators using clean hydrogen. This paper derives a marginal fixed premium that can be used as an indicator of securing the economy of the VCHP platform. The VCHP platform design and operation algorithm consists of two optimizations. The first optimization analyzes the behavior of Photovoltaic (PV) in renewable energy concentration areas, and the second optimization supplies power and heat to load concentration areas through optimal scheduling of Fuel Cell (FC).

Drawing transformation pathways for making use of joint effects of food and energy production with biodiversity agriphotovoltaics and electrified agricultural machinery

The achievement of the Sustainable Development Goals is being pursued worldwide. While energy production and consumption are to be oriented towards renewable energies, ecologically and socially sustainable agriculture is also a target for science and society. Due to the expansion of renewable energies, agricultural land in particular is the focus of various interest groups, from food production to energy production. In this interdisciplinary study, we show the opportunities and limits of joint synergies from the nexus of food production, energy production, energy consumption, biodiversity protection and social acceptance of renewable energies in a scenario. Biodiversity agriphotovoltaics, i.e. agriphotovoltaics in combination with biodiversity protection measures, such as flower strips, can make a valuable contribution to promoting biotope connectivity in addition to significant energy production. We show this in a GIS-based regional assessment for Lower Saxony in northern Germany. This rough spatial assessment is followed by a modelling of energy production and consumption during the cultivation of a characteristic agricultural field in the loess region of Lower Saxony. Our focus here is on the possibilities of using cable electricity or battery storage for carrying out the cultivation. In an accompanying survey of farmers regarding the use of agriphotovoltaics, we collected and evaluated their prior knowledge, experiences, and attitudes towards this technology. Finally, we show which advantages agriphotovoltaics and electrified agricultural machinery can also have for the sustainable transformation of agriculture and which challenges exist for a truly sustainable use of these technologies.

Sector Coupling and Migration towards Carbon-Neutral Power Systems

There is increasing interest in migrating to a carbon-neutral power system that relies on renewable energy due to concerns about greenhouse gas emissions, energy shortages, and global warming. However, the increasing share of renewable energy has added volatility and uncertainty to power system operations. Introducing new devices and using flexible resources may help solve the problem, but expanding the domain of the problem can be another solution. Sector coupling, which integrates production, consumption, conversion, and storage by connecting various energy domains, could potentially meet the needs of each energy sector. It can also reduce the generation of surplus energy and unnecessary carbon emissions. As a result, sector coupling, an integrated energy system, increases the acceptance of renewable energy in the traditional power system and makes it carbon neutral. However, difficulties in large-scale integration, low conversion efficiency and economic feasibility remain obstacles. This perspective paper discusses the background, definition, and components of sector coupling, as well as its functions and examples in rendering power systems carbon-neutral. The current limitations and outlook of sector coupling are also examined.

Experimental investigation of the soiling effect on the PV systems performance and the cleaning intervals in Oman

The trend toward diminishing dependence on fossil fuels as an energy source has become a government obsession, resulting in the acceptance of renewable energy as an alternative green energy source. Photovoltaic energy is considered the most viable renewable energy source in the MENA region due to the high solar irradiation level and the number of clear sky days during the year. However, environmental factors such as dust limit the optimum utilization of the source. In this paper, the effect of the accumulated dust on the Photovoltaic module surface has been studied for six months in Oman's weather conditions to suggest an economical cleaning interval. The experiment was conducted on a 5.85 kW grid-tie ground mount system with two strings of 9 modules in series. Two manual cleaning intervals have been applied on each string to observe the effect of the dust on the PV system performance. The results show that the dust accumulation reduced the PV modules' current performance by up to 28 %, with the average current output of the uncleaned string measured at 4.1 A compared to 5.6 A from the cleaned string. Based on the study results, the recommended economic interval in Oman is 8–12 cycles annually, and it is expected to increase in the summer compared to the winter season. This work offers valuable insight to investors, consultants, PV plant O&M companies, PV engineers, and researchers offering prosecutable strategies for optimizing PV system efficiency in Oman.

Modeling public acceptance of renewable energy deployment: a pathway towards green revolution

Renewable energy adoption is a complicated process that is influenced by a multitude of different factors. Previous studies seldom examine the social acceptance of renewable energy from the Chinese perspective in Shandong province. To bridge this gap, comprehensive research is crucial to find the public attitude towards renewable energy. We extended the theory of planned behavior by incorporating three additional factors, i.e., risk perception, environmental concern, and belief about renewable energy costs. A questionnaire survey was conducted in the four major cities of Shandong province. The Logit model was used to determine possible factors affecting public acceptance. Research findings reveal that residents significantly support renewable energy regarding its positive environmental impact. Individuals’ education, personal income, awareness and belief of renewable energy consumption cost positively affect their intention to utilize renewable energy, as the willingness to pay increases with an increase in these factors while decreasing with individuals’ age. Young people with higher education and income are willing to pay extra for green energy. Research results emphasized the importance of enhancing public awareness and highlighting renewable energy benefits to win public acceptance of renewable energy deployment.

Social acceptance of renewable energy development in southern Spain: Exploring tendencies, locations, criteria and situations

Although, in general, there is a high level of public acceptance of renewable energies (RE) in Spain, at a local scale, protests and campaigns against RE projects are becoming increasingly frequent. In order to identify the factors that most influence the acceptance/rejection of renewable electricity generation technologies (photovoltaic, wind and biomass) at a local level, in this study we conducted a structured survey of the population of the province of Jaén in southern Spain. The analysis of the results of the questionnaire reveals that the social acceptance of RE plants is influenced by their location and size, and identifies the main criteria and situations that people take into consideration when deciding whether to support or reject RE projects. Although the results suggest that all RE technologies are widely accepted, they also highlight a preference for photovoltaic energy and for medium-sized plants in sites with low natural value. This article provides information and recommendations to facilitate the drafting of policies, plans and future studies that will enable social barriers to the implementation of RE technologies to be reduced, so helping accelerate the energy transition that is required in order for agreed climate targets to be met.

Consumer Acceptance of Renewable Energy in Peninsular Malaysia

Renewable energy (RE) is a type of advanced technology that changes natural energy into a form that can be used as an alternative to traditional energy solutions to help reduce problems caused by global warming. Nevertheless, consumers still have limited knowledge of renewable energy, which leads to an unwillingness to pay more. Renewable energy marketing as a sustainable willingness to pay more for renewable energy billpayers in Peninsular Malaysia. This research applied the theory of reasoned action as the theoretical underpinning theory. A questionnaire survey was distributed to taxpayers, and 3209 usable responses out of 5000 persons were obtained. This paper suggested that consumers’ concerns and knowledge of renewable energy were positively related to paying a premium for renewable energy. This research showed that the energy consumption patterns influenced consumers’ willingness to pay more for renewable energy. This will benefit policymakers, in line with the Twelfth Malaysian Plan, in pursuing green technology growth and recommending the policy measure to achieve the country’s 31% and 40% renewable energy targets in 2025 and 2035, respectively.
