Research on Source-grid Coordinated Dispatch Control Strategy in Large-scale Urban Power Grid

Aiming at the problem of coordinating generators with electrical network with uncertain wind power output, this paper fully considers the system operation risk caused by system wind speed, load demand prediction error and unit forced shutdown rate. The cost model of thermal power depth peak regulation is established. By turning it into an optimization target, this paper constructs a model of coordinated economic dispatch including wind power system source network. The constraint conditions consider the safety constraints such as power balance unit output climbing. Through the example by Matlab, it shows the relationship between the system's power generation cost and risk devaluation, risk underestimation and overestimation cost coefficient. The validity of the proposed multi-target source-grid coordinated dispatch model is verified.
