Source-load Cooperative Optimization Dispatch Strategy Considering Wind Power Accommodation

Abstract

In order to improve the proportion of wind power accommodation, a source-load cooperative dispatch strategy based on genetic algorithm was proposed. The purpose of this dispatch strategy is to alleviate the problem of large-scale wind power curtailment, which is caused by the anti-peak regulation characteristics of wind power. Based on the voluntary participation of users in grid dispatching, the influence mechanism of excitation-type demand response participating in power grid dispatching on wind power consumption was analyzed. The source-load coordination optimization model was established with the goal of minimizing the total cost of the system. On the premise of ensuring the safety and reliability of the system, genetic algorithm was adopted to solve the model, Matlab was used to carry out simulation calculation on the calculation example in this paper. The results show that the proportion of wind power increase by 27.56%, and the total dispatch cost decrease by 4798 RMB, whichverify the effectiveness of the proposed strategy.
