“…The results obtained from the application of the mathematical model developed in this study are in accordance with other sizing and optimization techniques commonly used for the feasibility analysis of renewable-energy-based hybrid systems. For example, [68,78,79] reported LCOE estimates ranging from 0.196 to 0.410 $/kWh. Furthermore, these studies also showed that the hybridization of energy sources in autonomous systems provides a substantial reduction of the total annualized costs and CO 2 emissions.…”

Hybrid energy systems (HESs) generate electricity from multiple energy sources that complement each other. Recently, due to the reduction in costs of photovoltaic (PV) modules and wind turbines, these types of systems have become economically competitive. In this study, a mathematical programming model is applied to evaluate the techno-economic feasibility of autonomous units located in two isolated areas of Ecuador: first, the province of Galapagos (subtropical island) and second, the province of Morona Santiago (Amazonian tropical forest). The two case studies suggest that HESs are potential solutions to reduce the dependence of rural villages on fossil fuels and viable mechanisms to bring electrical power to isolated communities in Ecuador. Our results reveal that not only from the economic but also from the environmental point of view, for the case of the Galapagos province, a hybrid energy system with a PV–wind–battery configuration and a levelized cost of energy (LCOE) equal to 0.36 $/kWh is the optimal energy supply system. For the case of Morona Santiago, a hybrid energy system with a PV–diesel–battery configuration and an LCOE equal to 0.37 $/kWh is the most suitable configuration to meet the load of a typical isolated community in Ecuador. The proposed optimization model can be used as a decision-support tool for evaluating the viability of autonomous HES projects at any other location.

“…The author depended on a PV source to supply a dc load which is not the case in real life. Altun and Kilic 22 introduced a method for the optimal design of a hybrid system based on minimization of levelized COE and CO 2 emissions. The result claimed that the hybrid system is lower cost and CO 2 emissions than diesel system only, also that the diesel and batteries have a large part of the cost.…”

The optimal sizing of a hybrid energy system may be a difficult undertaking problem because of the huge number of structure settings and the irregular nature of solar radiation and wind power sources. This issue has a place with the classification of combinatorial enhancement, and its solution dependent on the classical technique may be a waste of time. In the present paper, the generation cost of isolated PV-wind by bird system is minimized by increasing the capacity factor of the system by adjusting both of PV-tilt angle and wind turbine hub height such that the average generated power is as near as possible to the generation peak. By considering the PV-tilt angle and the turbine hub height, the diversity between the two generation patterns increases resulting in lower cost. The objective of the present paper is to find the optimal design of the PV-wind hybrid system based on minimum cost criterion using a genetic algorithm. Also, it studies the effect of considering the PV-tilt angle and wind turbine hub height as design parameters for different diversity levels of wind speed and sun irradiance patterns.

Summary Nowadays, due to the pollution arising from the consumption of fossil fuels, destructive effects of pollutants on humans and the environment, and the reduction of reserves of these energy resources, the tendency to utilize renewable energy to meet energy needs has increased. In this investigation, first, a grid‐connected photovoltaic‐wind‐battery (PWB) hybrid system for an educational building is designed and optimized by implementing a genetic algorithm in MATLAB. The main goal is to minimize the annual total cost (ATC) and find the optimal sizes. The balance between the high costs of renewable electricity generation and the setting up a renewable system is achieved by applying the renewable energy fraction (fRE). In the second part, a photovoltaic‐wind‐fuel cell (PWF) hybrid system is designed and optimized in the same approach. A novel techno‐economic‐environmental comparison is performed to select the battery bank or hydrogen system as energy storage. Considering the environmental penalties, the effect of the environmental cost on the optimal sizes of components and annual total costs is investigated. Owing to the low tariff of the grid electricity as well as the high cost of the renewable systems, results confirms that the use of renewable systems is not cost‐effective. Also, if the authorities and householders intend to implement a storage system to store electricity, battery bank is less expensive than fuel cell system. To apply scenarios to increase renewable energy penetration, a comprehensive sensitivity analysis on the ATCs and optimal sizes is conducted technically and economically. Highlights Designing, optimizing, and comparing of PWB and PWF systems are investigated GA in MATLAB is implemented to determine optimal sizes and minimum ATCs A comprehensive sensitivity analysis is performed on the ATCs and optimal sizes The installing of the hybrid systems with the current tariffs is not cost effective Superiority of the battery bank over the hydrogen system in residential storage
