Feasibility Analysis and Development of Stand-Alone Hybrid Power Generation System for Remote Areas: A Case Study of Ethiopian Rural Area

This paper proposed a standalone solar/wind/micro-hydro hybrid power generation system to electrify Ethiopian remote areas that are far from the national utility grid. The aim is that it will lead to the development of renewable energy sources, using a hybrid optimization model for energy renewables (HOMER) as an optimization and sensitivity tool and MATLAB as a design tool. The system uses 100% renewable energy. This system incorporated solar photo-voltaic (PV), wind turbines, micro-hydro systems, and battery systems. The net present cost of the system is $4,377,731, incorporating capital depreciation and levelized operation and maintenance costs. During the hybrid energy system’s lifetime, the cost of a grid extension power supply is $22.185 million, which is nearly $17,808,000 more than the cost of the proposed standalone system. So, developing solar/wind/micro-hydro hybrid power generation will save $17,808,000 versus extending the national utility grid. As a result of a thorough examination of renewable energy resources, standalone solar, wind, and micro-hydro hybrid power generation is a technically and economically viable option for the case study area of Maji town.

Chance-constrained programming for optimal scheduling of combined cooling, heating, and power-based microgrid coupled with flexible technologies

• New comprehensive framework for a CCHP-based MG operation. • New CCP approach for guaranteeing confidence level of the whole system. • Proposing a comparative structure for participating in power and heat markets. • Utilizing multi-carrier storage, hybrid chiller, besides new mathematical for CHP. Microgrids (MGs) have a special role in developing several consumers' energy infrastructure and supply in more economical, safer, and sustainable ways. The interaction and mutual relationship between each energy carrier on the reliable performance of other carriers and the high growth of tri-generation technologies in the MG face the optimal performance of such networks with many challenges. Combined cooling, heating, and power (CCHP)-based MGs are a new generation of MGs that simultaneously provide electrical, thermal, and cooling loads. However, the interaction between these carriers is very influential in CCHP-based MG's operation, which is rarely analyzed. Hence, this paper focuses on the operation of CCHP-based MG coupled with hybrid chiller, multi-energy storage, solar and wind power, etc., under the chance-constrained programming (CCP) approach by considering the mutual relationship between carriers. While modeling consumption and wind and solar energies fluctuations, the proposed approach analyzes the violation of the balance constraint for each carrier and subject it to guarantee the corresponding confidence level. Therefore, the degree of dependence of the system on each carrier and the mutual relationship between carriers are analyzed in this work. This paper also presents a new incentive framework for participating in the electricity and heating markets for the system. The proposed model is implemented on the test system, and the results are discussed for different cases for several confidence levels. The results illustrate the importance of the electricity carrier confidence level on the safe performance of the whole system compared to other carriers. Only by increasing the operation cost of the electricity sector by 4.3%, the system's reliable performance is guaranteed with a probability of 98%.

An improved fuzzy multi-criteria algorithm for optimizing concentrated solar power (CSP) hybridized systems based on pythagorean fuzzy set

In concentrated solar power (CSP) hybridized systems, the selection of solar-hybrid power plants (SHPP) is very important, especially when the selected criteria and performance indicators are fuzzy and uncertain. The multi-criteria intuitionistic fuzzy decision-making method for selecting SHPP has been widely studied. Thus, the purpose of this paper is twofold. Firstly, we present the improved version of the Cavallaro et al., [2018]’s method. Improvement aspects include formulas expression, calculation data, intuitionistic fuzzy matrix, entropy, weights and the weighted correlation coefficient. After the improvement, the ranking result of the various alternatives (ISHCC-1, ISHCC-3, ORC-1, ST-1, ORCREC-3, PT-3, PART-1, PART-3) is changed from “OREREC-3 ≻ PART-3 ≻ ISHCC-3 ≻ ST-1 ≻ ORC-1 ≻ ISHCC-1 ≻ PT-3 ≻ PART-1” to “OREREC-3 ≻ PART-3 ≻ ISHCC-3 ≻ ST-1 ≻ ORC-1 ≻ ISHCC-1 ≻ PART-1 ≻ PT-3”. Secondly, an improved fuzzy multi-criteria algorithm for optimizing concentrated solar power (CSP) hybridized systems based on Pythagorean fuzzy set is presented. Where, a new weighted correlation coefficient based on Pythagorean fuzzy set is proposed. On the one hand, the effectiveness of the proposed method is demonstrated by comparing with the different methods in the medical diagnosis application, which shows that the new method is as efficient as the other methods. On the other hand, we use the proposed method to re-rank differ solar power hybridized systems with the purpose of strengthening the ranking results. The re-ranking results we get are still: OREREC-3 ≻ PART-3 ≻ ISHCC-3 ≻ ST-1 ≻ ORC-1 ≻ ISHCC-1 ≻ PART-1 ≻ PT-3. It further indicates that the modified results given in this paper are correct. Furthermore, the proposed new sorting method based on Pythagorean fuzzy set is effective and reasonable. The refinement will help readers understand Cavallaro et al., [2018] well, and then apply intuitionistic/Pythagorean fuzzy multicriteria algorithm in related issues better.

Application of spectral beam splitting using Wavelength-Selective filters for Photovoltaic/Concentrated solar power hybrid plants

• A spectral beam splitting hybrid solar power is proposed. • Annual performance and cost benefit based on the developed filters are estimated. • The proposed hybrid is useful for a retrofit aging concentrated solar power plants. • Both the annual efficiency and the levelized cost of electricity can improve by 9%. To maximize the utilization of solar energy, this study focuses on the investigation of a realistic performance of a photovoltaic/concentrated solar power hybrid using a developed wavelength-selective filter. The hybrid system is proposed for the modification and improvement of the performance of the currently operating solar electric generating station VI parabolic trough plant in California, USA. In the hybrid, photovoltaic system converts only the useful wavelengths after the splitting of the solar irradiance by the wavelength-selective filter, and the concentrated solar power uses the remaining wavelengths. Most relevant studies presented the hybrid performance using hypothetical filters instead of realization. Even studies utilizing realized filters have only used annual mean values to assess hybrid performance. Due to the intrinsic properties in real filters, the hybrid performance can be varied accordingly throughout the day and year. As a result, by presenting annual performance based on the measured optical properties of a real filter, this study intends to address this research gap. According to the findings, the proposed hybrid performed 9% better than the solar electric generating station VI concentrated solar power. The hybrid system was also 4% more efficient than the virtual photovoltaic-alone system. The proposed hybrid’s Levelized Cost of Electricity is 9% lower than the solar electric generating station VI concentrated solar power. Even if the proposed filter accounts for 18.4% annual optical loss from the incident solar power, the proposed hybrid is still very promising for retrofitting and enhancing aged concentrated solar power plants.

The research results are obtained based on the comparison of both systems which are the Hybrid system used with a 1,200 Wp panel, 2 series 24V 100 Ah batteries, and a 1,500 W inverter, while On-grid system uses a 1,200 Wp panel and 1,500 W inverter. The On-grid design will produce electrical energy of 4,57 kWh/kWp/day with an initial investment value of USD 1,733.70 while the Hybrid design will produce 4,04 kWh/Kwp/day with an initial investment value of USD 1,871.63 for a 24 years project period and with approximately four times batteries replacement. The NPV value in the Hybrid system calculated is USD 1.43 and in the On-grid system is USD 1,700. Therefore, the Hybrid system is considered not economically feasible and does not gain more profit than On-grid System.

A New Sustainable and Novel Hybrid Solar Chimney Power Plant Design for Power Generation and Seawater Desalination

This study presents a case study of a novel hybrid solar chimney power plant (HSCPP) design’s performance in the city of Doha, Qatar. The HSCPP construction is similar to the traditional solar chimney power plant (SCPP) but with the addition of water sprinklers installed at the top of the chimney. This allowed the solar chimney (SC) to operate as a cooling tower (CT) during the nighttime and operate as an SC during the daytime, hence providing a continuous 24-h operation. The results showed that the HSCPP produced ~633 MWh of electrical energy per year, compared to ~380 MWh of energy produced by the traditional SCPP. The results also showed that the HSCPP was able to produce 139,000 tons/year of freshwater, compared to 90,000 tons/year produced by the traditional SCPP. The estimated CO2 emission reduction (~600 tons/year) from the HSCPP is twice that of the traditional SCPP (~300 tons/year). The results clearly show that the HSCPP outperformed the traditional SCPP.

Progressive Development and Challenges Faced by Solar Rotary Desiccant-Based Air-Conditioning Systems: A Review

A rotary desiccant-based air-conditioning system is a heat-driven hybrid system which combines different technologies such as desiccant dehumidification, evaporative cooling, refrigeration, and regeneration. This system has an opportunity to utilize low-grade thermal energy obtained from the sun or other sources. In this paper, the basic principles and recent research developments related to rotary desiccant-based cooling systems are recalled and their applications and importance are summarized. It is shown that with novel system configurations and new desiccant materials, there is great potential for improving the performance and consistency of rotary desiccant systems; at the same time, the use of solar energy for regeneration purposes can minimize the operating cost to a great extent. Some examples are presented to demonstrate how rotary desiccant air conditioning can be a promising solution for replacing traditional vapor-compression air-conditioning systems. Recent advances and ongoing research related to solar-powered hybrid rotary desiccant cooling systems are also summarized. The hybrid systems make use of a vapor-compression system in order to have better operational flexibility. These systems, although they consume electrical energy, use solar energy as the principal source of energy, and hence, significant savings of premium energy can be obtained compared to conventional vapor-compression systems. However, further research and development are required in order to realize the sustainable operation of solar rotary desiccant air-conditioning systems, as solar energy is not steady. Reductions in capital cost and size, along with improvements in efficiency and reliability of the system is still needed for it to become a player in the market of air conditioning.

Exploring the Regulation Reliability of a Pumped Storage Power Plant in a Wind–Solar Hybrid Power Generation System

In the coming decades, the proportion of wind–solar energy in power system significantly increases, resulting to uncertainties of power fluctuation in abundant wind–solar energy regions. The flexibility operation of Pumped Storage Power Plants (PSPPs) has already been widely recognized to regulate wind–solar power fluctuations; however, less is known about the regulation reliability of the PSPP affected by them. It is a challenge, since various uncertainties exist during this regulation process. Here, a mathematical model with a solar–wind–hydro hybrid power generation system is adopted to investigate the regulation reliability of PSPP. The uncertainties and limitations of model parameters are considered during this process. Five regulation indexes, i.e., rise time, settling time, peak value, peak time and overshoot of the reactive power generator terminal voltage, guide vane opening and angular velocity, are extracted to evaluate the PSSP’s regulation quality. Finally, the PSPP reliability probability affected by parametric uncertainties is presented. The obtained results show that the inertia coefficient is the most sensitivity parameters for the settling time, peak value and peak time with sensitivity index 33.7%, 72.55% and 71.59%, respectively. The corresponding total contribution rate of the top 10 sensitive parameters are 74.45%, 93.45% and 87.15%, respectively. Despite some types of uncertainties not being considered, the results of this research are important for the regulation reliability evaluation of PSPPs in suppressing power fluctuations of wind and solar generation.

New integration mechanism of solar energy into 300 MW coal-fired power plant: Performance and techno-economic analysis

The hybridization of solar energy with a coal-fired power plant is a promising way to reduce the numerous environmental issues related to a coal-based power generation sector. This paper examines a novel integration mechanism of solar energy into a 300 MW coal-fired power plant to improve the performance and techno-economic feasibility of the proposed system while decreasing pollutant emissions by coal consumption reduction. The concept of a novel integration mechanism includes replacing a part of the steam being used in the steam turbine of the proposed system with steam produced using the solar field installed near the power plant. The performance and techno-economic analysis of a 300 MW solar coal hybrid power generation (SCHPG) system were investigated under four different reference days (i.e. 22nd of March, 22nd of June, 22nd of September, and 22nd of December). Although the results revealed that the SCHPG system can operate well over the year, it exhibited the highest performance and techno-economic feasibility for the 22nd of June due to the higher direct normal irradiance and small incidence angle. In contrast, the lowest performance and techno-economic feasibility occurred on the 22nd of December. Besides, the performance and techno-economic feasibility for the 22nd of March and 22nd of September are almost similar.

Analysis of hybrid solar biomass power plant for generation of electric power

The need of world electricity production is growing at an increasing rate and because of its limited supply, it cannot completely be met by ordinary energy framework. The use of hybrid systems by renewable electricity sources for energy generation has also created considerations in general. There is no one source of renewables ready to continuously load electricity, and hybrid systems are thus a key solution. Renewable energy is produced by inexhaustible reserves, usually refilled on a human scale, such as sun, wind, hydro, mainstay, biomass, etc. In four core areas, renewable energy often provides energy: electricity, air and water heating/cooling, transport, and rural (stand-alone and network) energy services. In comparison with other sources, renewable power sources have reserves in large geographical regions amassed in a small number of countries. Rapid organization of renewable energy sources and energy conservation brings enormous energy stability, ecological change relief and financial benefits. Hybrid systems (PV-Biomass) are used in different regions to provide electricity to overcome discontinuity and transition in solar and wind power. This paper discusses the techno-economic feasibility analysis of solar biomass system in the Ludhiana district of Punjab.

The source of electricity supply in isolated areas is commonly from diesel or other fossil fuel-based generation systems. However, the increasing cost and harmful emissions of these fuels have led researchers to seek alternative solutions in providing electricity. Hence, harnessing renewable resources can be a favourable solution in lowering the dependency on fossil fuels. The Strait of Malacca is blessed with tidal current energy, a research was conducted to design a hybrid renewable energy system (HRES) that consists of tidal current and solar energy as its sources along with backup power such as generators to support the electrical demand of a lighthouse. A simulation method is used to determine and compare the optimal configuration of the HRES with the diesel generator-based system. An evaluation of all possible scenarios of standalone systems was carried out by considering the amount of fuel consumption and pollutant emittance, capacity shortage, excess electricity production, unmet energy and renewable fraction parameters of each system scenario. From the findings, the hybrid energy system of Scenario A that consists of tidal turbines, PVs, generator, battery, and converter produces better results where the diesel fuel consumption can be reduced up to 84% in comparison with the standalone generator-based system.
