Research on Power Grid Dispatching Considering Demand Response and Wind Power Uncertainty
摘要
Abstract
In view of the increasing influence of wind power uncertainty on power system,this study proposes an economic dispatching method of power grid source-load network considering demand response.According to the price elasticity theory of demand and the principle of consumer psychology,a price-based demand response model is constructed.Based on flexible compensation incentive demand response,the complementary characteristics of the two types of demand responses are fully considered,and the reserve constraints of the two types of demand responses on the system are increased.The general probability distribution is introduced to describe the output characteristics of wind power,and the expected cost is used to quantify the uncertainty of wind power to punish the cost.The nonlinear variables in the objective function are linearized,and the mixed integer linear programming problem is used to solve the model.The simulation results show that the proposed model can effectively reduce the peak-valley difference of load and improve the absorptive capacity of wind power.关键词
