“…In both papers, and the obtained results are compared with the HOMAR software, and the optimal result of GA is more cost-effective than HOMAR. For minimizing the total/net present cost of the HES encompassing solar PV, wind, diesel generator, and battery for electrifying rural areas in stand-alone applications, a suitable improved GA program has been developed in [30] utilizing the MATLAB toolbox. The size of gridconnected solar and battery systems for residential houses is optimized using a genetic algorithm in [31] to reduce the overall yearly cost of electricity.…”

Optimal sizing of the power system can drastically reduce the total cost, which is challenging due to the fluctuation in output power of RE (primarily wind and solar) and pollution from thermal generators. The main purpose of this study is to cope with this output power uncertainty of renewables by considering ADLC, residential PV, and BESS at the lowest cost and with the least amount of carbon emission, while putting less burden on consumers by minimizing the IL. This paper optimizes the cost and carbon emission function of a hybrid energy system comprising PV, WG, BESS, and DG at Aguni Island, Japan, using a multi-objective optimization model. To solve the proposed problem in the presence of ADLC, the ϵ-constraint method and MILP are utilized. After obtaining all possible solutions, the FSM selects the best possible solution among all solutions. The result shows that while case 1 has a lower energy cost than the other cases, the quantity of IL is quite significant, putting customers in a burden. In case 2 and case 3, the total energy cost is 11.23% and 10% higher than case 1, respectively, but the sum of the IL is 99% and 95.96% lower than case 1 as the ADLC is applied only for the consumers who have residential PV and BESS, which can reflect the importance of residential PV and BESS. The total cost of case 3 is 1.72% lower than case 2, but IL is higher because sometimes home PV power will be used to charge the home BESS.

The hybrid renewable energy system is a promising and significant technology for clean and sustainable island power supply. Among the abundant ocean energy sources, tidal current energy appears to be very valuable due to its excellent predictability and stability, particularly compared with the intermittent wind and solar energy. In this paper, an island hybrid energy microgrid composed of photovoltaic, wind, tidal current, battery and diesel is constructed according to the actual energy sources. A sizing optimization method based on improved multi-objective grey wolf optimizer (IMOGWO) is presented to optimize the hybrid energy system. The proposed method is applied to determine the optimal system size, which is a multi-objective problem including the minimization of annualized cost of system (CACS) and deficiency of power supply probability (DPSP). MATLAB software is utilized to program and simulate the hybrid energy system. Optimization results confirm that IMOGWO is feasible to optimally size the system, and the energy management strategy effectively matches the requirements of system operation. Furthermore, comparison of hybrid systems with and without tidal current turbines is undertaken to confirm that the utilization of tidal current turbines can contribute to enhancing system reliability and reducing system investment, especially in areas with abundant tidal energy sources.

“…If there is an excess of power generated from the PV and WT sources the electrolyser will produce hydrogen which will be stored for further consumption. In the case the energy generated from RES is not enough to supply the entire building the fuel cell will generate the required power using the already stored hydrogen [12,15,16].…”

This contribution presents a comparative study of operating a green energy hybrid system to sustain the power production mix of an office building. For this purpose, two scenarios of a hydrogen storage system (S1) and battery energy storage (S2) to sustain solar and wind energy inlets were compared from a technical, environmental and financial perspectives. S1 - hydrogen technology system was found to be more performing than S2 - battery technology in terms of energy efficiency, as well as CO2 emissions and initial costs.
