[0003] However, due to the randomness and volatility of new energy power generation, it is easy to weaken the controllability of the power generation side of the power system. Especially with the rise of the smart grid, a large number of flexible loads are connected to the user side of the smart grid, which has a greater impact on power grid regulation. Large, representative ones include air conditioners and electric vehicles, in which air conditioners are high-power power-consuming equipment, and electric vehicles are high-power charging and discharging equipment. The optimal control of flexible loads can easily lead to large fluctuations in grid load, which cannot ensure the safe operation of the grid

[0004] Therefore, the current power grid control method is difficult to optimally control various flexible loads in the power grid, and it is easy to cause large fluctuations in the power grid load.
