Industrial electricity consumption constitutes a significant portion of the total societal electricity usage. Green microgrids are a crucial approach to harmonizing the three objectives of reliability, economic efficiency, and low carbon footprint in industrial electricity usage, thereby enhancing energy utilization efficiency. This paper establishes a mathematical model for three types of power sources: photovoltaic (PV), diesel generators, and energy storage systems. The photovoltaic unit employs a maximum power point tracking (MPPT) control based on the incremental conductance method. Through the coordinated control between the energy storage system and the diesel generator system, the impact of the stochastic output of the photovoltaic system is mitigated, ensuring the stable power supply of the microgrid. Simulation results demonstrate that the industrial green microgrid model constructed in this study is reasonably sound.
