The high penetration of renewable energy increases the difficulty of optimal dispatch and brings challenges to the safe and economic operation of the distribution network. This paper proposed an active and reactive power coordinated optimal dispatch model, and the spatial-temporal correlation of wind power output is considered. Firstly, the copula function and non-parametric estimation methods are adopted to model the spatial-temporal correlation of wind power. Secondly, the parameters in the copula fitting function are estimated based on the maximum likelihood estimation method. Besides, the active power and reactive power outputs of various flexible resources in the active distribution network (ADN) are coordinated. The proposed model can significantly reduce the network loss of the ADN, improve efficiency, and optimize the power purchase plan. A case study on a modified IEEE 33-bus system verified the effectiveness of the proposed method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
