Description
technical field [0001] The invention relates to the technical field of microgrids, in particular to a microgrid battery energy storage configuration method and a readable storage medium. Background technique [0002] In order to solve the energy crisis and improve environmental quality, efficient use of renewable energy has become a social development trend. However, renewable energy, such as wind, light and other energy sources, has the disadvantages of strong intermittent and high volatility. The output curve of these energy sources fluctuates greatly. Direct access to the power grid will cause the power flow of the power grid to flow in two directions, and the flow direction changes frequently, which will lead to the problem of voltage rising and crossing the line in some parts of the power grid, affecting the quality of the power grid and threatening the safety of electricity consumption. The battery energy storage system (BatteryEnergyStorageSystem) can better solve th...
