Optimization of Power Output Ratio for Micro-Grid System with Renewable Generation and Energy Storage

Reasonable planning of wind farms, photovoltaic power plants, and energy storage systems can improve the economic efficiency and reliability of micro-grid systems. In order to obtain the optimal power output ratio of the micro-grid system, the maximum profit of the micro-grid system is set as the objective function, with energy utilization rate, system outage rate, and savings in electricity purchasing costs as evaluation criteria. Genetic algorithms are used to optimize the micro-grid system. Secondly, different scenarios of micro-grid system combinations are established, and evaluation criteria are used for assessment. Finally, within the constraints, the optimal power output ratio of the micro-grid system is obtained based on the impact of the micro-grid system on the objective function, verifying the scientific and effective nature of the proposed model.
