Abstract
Nowadays,power systems are a critical part of daily life.In order to ensure the stability of the power system,this paper first uses virtual inertia injection method to simulate the inertia characteristics of the power system.Secondly,constraints are established to ensure the stability of the power system and provide a basis for subsequent load current curtailment.Finally,a load curtailment optimization model is constructed to realize the load curtailment optimization of the power plant.The load curtailment optimization of the power plant is analyzed from two aspects:optimization results and load distribution response speed.The results show that the coal consumption and deviation of the proposed method are low,which are 318.59 t and 0 respectively,and the load distribution speed is fast,generally about 4.9 s.It proves that the proposed method consumes less energy,has high accuracy,and has fast unit response,thereby can complete the load curtailment optimization of the power plant,maintain the stability and balance of the power system,and promote the development of the power system.关键词
