[0003] While studying the stability and safety of the power system, the operation mode of the power supply and the model selection of the electrical equipment will be considered, and a certain power consumption capacity will be set in advance. When the load runs continuously or is disturbed, the power loss will be too large , will lead to overload operation of lines and electrical equipment, affecting the safety of the power grid and the normal operation of the load

[0004] Usually, the fast switching compensation device is used to improve the load loss energy and make control decisions in terms of stabilizing the supply voltage and power factor. However, in the process of some parameter changes and load dynamic fluctuations, such compensation effects often fail to achieve the expected goal. , it will appear that in a certain period of time, the compensation voltage and power factor increase, and in the next period, the voltage drops or fluctuates again, the grid operation is still not fast and stable, and the power loss compensation cannot reach the expected value
