“…The iHOGA uses advanced models to accurately estimate the battery's service life [32] and can correctly compare the performance of different combinations of systems and control strategies to obtain the best solution, so the total net present cost (NPC) of the system is estimated by iHOGA. Some studies on simulation and optimization of HRESs using iHOGA software can be found in the literatures [34][35][36][37].…”

With continuous fossil energy consumption and global warming, renewable energy has become more popular. Therefore, more and more researchers have begun to study hydrogen-based hybrid renewable energy systems. This article mainly summarizes the commercial software tools and the simulation of hybrid renewable energy systems in recent years. Firstly, the commonly used softwares and research methods are reviewed so that other researchers can choose suitable tools and strategies to conduct their researches. Then TRNSYS software is used to perform a case study in Yichang, Hubei, China. The established model is simulated according to the one-year load of the community. The simulation results show that the total power generation of the system can meet the load demand most of the time but is insufficient in some peak periods. The system can further be optimized using optimization methods to fully meet the load.

“…The sensitivity variables were solar radiation, average annual wind speed and the PV panel price. Tawfik et al [35] established a most economical HRES based on NPC to provide energy for a seawater desalination device. Although the most economical configuration was obtained, there was a mismatch between the system and the load.…”

“…In a study that investigated the performance of various possible configurations using iHOGA software, the achieved optimum configuration was further improved by adapting the daily load pattern to the periods of high renewable generated energy to increase direct energy utilization rather than charging batteries [29]. This will result in effective minimization of battery bank size.…”

Solar and wind energy systems are considered as promising power-generating sources due to their availability and advantages in local power generation. However, a drawback is their unpredictable nature. This problem can be partially overcome by integrating these two resources or more in a proper combination to form a hybrid energy system. Nevertheless, the harmonization of different energy sources, energy storage, and load requirements is a challenging task. Thus, the performance of various possible configurations has to be investigated to reach the optimum combination using a simulation program. The number of simulations and time required for calculation increases with the increase in number of optimization variables. Therefore, the selection of a quick and accurate optimization technique is very important. Different software packages, such as HOMER and iHOGA, were developed, where each of them is based on a different optimization algorithm.

This paper focused on a techno-economic study of a standalone PV/battery system for electrical energy supply. For a particular case study in Cameroon, the system is optimally designed thanks to a double-objective firefly optimization algorithm, based on a defined operational strategy. The two objective functions simulated simultaneously using FA are: the cost of energy (COE) function and the function defining the loss of power supply probability (LPSP). Different optimal configurations of the system have been obtained on the Pareto front with respect to their LPSP. For a total load demand of 20196.7 kWh, the lowest cost configuration with LPSP of 0% is composed by a number of 63 modules and a battery capacity of 370.295 kWh. The related COE is 0.2587 $/kWh, corresponding to a total net present cost of 87422 $. However with this configuration, the energy of batteries could not be able solely to respond to the energy demand for 3 continuous days. In that case, the increase of the PV power production (by increasing the number of PV modules) could allow to the batteries to fulfil this deficiency. But this solution increases the investment cost to up to 11.17%, considering a system with 80 PV modules. Another solution consists in reducing the size of the battery bank to avoid its unnecessary oversizing. In this case, the COE and the system investment cost reduce to up to 28.77% for 1 day batteries’ autonomy considered. The obtained results have demonstrated that the cost of a PV/battery system is mostly influenced by the batteries’ size, while the system reliability is mostly related to the PV size.
