Regional Coordination Control of Active Distribution Network Based on Bidding Mechanism

Abstract

In order to improve the control effect and performance of the active distribution network (ADN), based on the control theory of the ADN feeder control error (FCE), the regional coordination control of ADN based on bidding mechanism is proposed.Firstly, the regional coordinationautonomy mode of ADN is introduced. The autonomous regions balance the power fluctuations according to the power coordination coefficient issued, and realize the ADN operation in a better state. Then, by adjusting the coordination coefficient in the FCE control equation, the proportion of power fluctuations in different regions is changed. By selecting the "price factor", "deviation tolerance factor" and "optimal distance factor" three bidders in line with the optimization direction, the optimal sharing of real-time power fluctuations in the ADN is realized. At last, a numerical example is given to verify the validity of the control method in this paper.
