Over the past decade, Chinese energy structure and power system technology have undergone tremendous changes. First, the proportion of new energy in power generation capacity is increasing, and the permeability of some areas has reached 30% - 50% of the total power generation capacity; second, the characteristic of power electronics in power system is becoming more and more obvious. The impact of these two aspects on the power system is that the power fluctuation of the power grid is intensified, and the power flow is flexible and changeable, which brings new challenges to the operation scheduling and simulation technology of the power system. Therefore, based on Power System Analysis Synthesis Program (PSASP) electromechanical transient simulation program, this paper studies and proposes a power grid regulation and control analysis method, it can help the dispatchers and operators to improve the dispatching plan and the accuracy of various kinds of anticipated faults. This method seeks to simulate the power flow fluctuation of the real power grid approximately. The validity of the proposed method is verified by the simulation calculation of some year national interconnection data.
