Enhance Flexibility of Distribution Systems by Dynamic Network Reconfiguration Wu Zhongshan, Qin Chao, Pei Yuting, Zeng Yuan, Sun Bing

Abstract

How to enhance the ability of distribution systems to cope with the volatility of renewable energy sources and load, i.e. flexibility, has become a crucial issue for power system operation. In this paper, a two-stage robust model is proposed, which considers the volatility and uncertainty of renewable distributed generators and makes full use of dynamic reconfiguration to enhance the flexibility of distribution systems. Furthermore, several flexibility indexes are proposed to quantitatively evaluate the flexibility from the perspective of whole horizon and each period. Finally, the IEEE-33 system is used to test the validity of the proposed method.
