Abstract

This article introduces a photovoltaic energy storage system capable of operating both on-grid and off-grid, jointly controlled by a maximum power point tracking algorithm based on incremental conductance method, an energy storage battery optimized using the slime mold algorithm, and a pre-synchronized virtual synchronous generator. The system can operate in parallel off grid mode and perform multifunctional operations, including reactive power compensation, power balance, and power quality enhancement, ensuring uninterrupted power supply to the load under different operating conditions. The proposed system uses the incremental conductance method to determine the maximum power output of the photovoltaic array. The energy storage converter, optimized by the slime mold algorithm, stabilizes the DC bus voltage, and the system switches off the grid through a virtual synchronous generator. The simulation experiment results show that the total harmonic distortion of the voltage and current in the optical storage system optimized based on the slime mold algorithm is 1.20% and 2.13%, respectively, which is below the 5% threshold limit, verifying the effectiveness of the proposed control system.
