A Day-Ahead Hierarchical Coordinated Scheduling Method for Active Distribution Networks

Abstract

The present invention provides a day-ahead layered coordinated scheduling method for an active distribution network, the method includes optimal scheduling of source-load resources; network reconstruction optimization among multiple feeders of the active distribution network; coordination and correction of source-load resources Active power output; determine the correction results of active power scheduling of each source and load resource; the technical solution provided by the invention can simplify the difficulty of active distribution network operation optimization, reduce the amount of calculation, maximize the use of distributed power sources, adjustable loads and distribution network reconstruction The advantage of it minimizes its damage and impact on the operation of the distribution network.

Description

technical field [0001] The invention relates to the field of power distribution system automation, in particular to a day-ahead layered coordination scheduling method for active distribution networks. Background technique [0002] As the penetration rate of distributed energy resource (DER) increases at all levels of the power system, the planning and operation of the power system, especially the distribution network, has become relatively complicated, which affects the economy and power of the distribution network. Regulatory methods have also had a greater impact. In order to cope with the challenges brought about by the increase in the penetration rate of distributed energy, the technical model of active distribution network has emerged as the times require. [0003] Active distribution network is a power distribution system that uses a flexible network topology to manage power flow for active control and active management of local DERs. In the traditional distribution n...
