Abstract
The type of solar panels has a great impact on the optimal sizing of a hybrid photovoltaic–battery scheme. The optimization of these schemes based on a powerful optimization approach results in more cost-effective schemes. In this paper, a new global dynamic harmony search method, as an optimization method, is presented for the optimal sizing of a hybrid photovoltaic–battery scheme. The new optimization method is aimed at minimizing the total cost and loss of load supply probability of the scheme at the same time. In this regard, the effect of the type of solar panels on the optimal sizing of the hybrid scheme is investigated. Furthermore, performance optimizations are performed with an original global dynamic harmony search, an original harmony search, and simulated annealing to determine the effectiveness of the suggested optimization method. The effects of the initial costs and efficiency of monocrystalline and polycrystalline solar panels on the optimization of hybrid systems are analyzed. The superiority of the suggested method in terms of time and cost indicators of the hybrid scheme is presented comparing the other algorithm.
Highlights
Renewable energies, as one of the alternative energy sources of fossil fuels, have attracted many researchers as a source of endless energy in the world [1,2]
The results show that the optimization method based on particle swarm optimization (PSO) can improve the accuracy of the results and achieve rapid convergence
Based on the above analysis, in order to identify cost-effective, safe, and reliable operation of power generation systems in remote areas, this paper proposes a new global dynamic harmony search (GDHS-I) algorithm as an optimization algorithm for the optimal sizing of a hybrid photovoltaic–battery scheme
Summary
As one of the alternative energy sources of fossil fuels, have attracted many researchers as a source of endless energy in the world [1,2]. Due to the uncontrollability and randomness of solar energy, solar power generation makes it difficult to meet the load demand in remote areas, which brings great challenges to the reliable and safe operation of solar power generation systems. To solve this problem, it is necessary to use energy storage and backup units. The hybrid photovoltaic–battery scheme is suggested for the reliable and safe operation of solar power generation systems in remote areas [12,13,14,15]
