Calculation of Load Optimization Ratio for Microgrids in Parks Based on Self-Balancing Requirements

In the context of “dual carbon”, park micro grids have become the main form of new energy consumption in areas with high load density due to their flexible regulation capabilities. How to achieve self-balance between supply and demand of park microgrid based on load optimization, and truly leverage the effectiveness of micro grids to alleviate the load pressure and consumption pressure of distribution network, has become a key issue in the development of microgrids. This paper establishes a microgrid power generation and consumption model based on the self-balancing constraint of micro grids, clarifying the requirements for the proportion of local new energy generation and local consumption of new energy in microgrids. Furthermore, a microgrid load optimization ratio algorithm was constructed to analyze the source load ratio, storage load ratio configuration, and load optimization ratio that meet the requirements of the micro grid. Finally, taking the load characteristic curve of a typical commercial park in a certain region as an example, the load optimization ratio calculation and analysis were carried out to verify the optimization effect of the proposed method.
