Research on Optimal Configuration of Photovoltaic and Energy Storage Systems Based on Operational Efficiency

With the remarkable growth in renewable energy, applications of photovoltaic power generation and energy storage have emerged as prominent research directions in current research. This paper puts forward an optimal configuration model that considers the operational efficiency of the photovoltaic and energy storage system. Considering system line losses and other losses, the operational efficiency is defined in the scenario of photovoltaic and energy storage systems. Then, a three-objective optimization model is proposed, which integrates the comprehensive revenue of the photovoltaic and energy storage system, the active power for grid-side peak-valley compensation, and the defined operational efficiency. Finally, the NSGA-II algorithm is employed to solve the problem and obtain the optimal configuration outcome. The simulation results demonstrate that the model presented in this paper can effectively enhance the economic viability and operational stability of the photovoltaic and energy storage system.
