Main network day-ahead scheduling method of considering active power regulation capability of active distribution networks

Abstract

The invention discloses a main network day-ahead scheduling method of considering the active power regulation capability of active distribution networks and belongs to the technical field of electricengineering. Information collection restrictions of main network scheduling and distribution network scheduling are considered. According to the method, conventional technical parameters of the main network and the distribution networks are collected separately to obtain load prediction curves of two stages of networks; detailed modeling is carried out on the main network and the distribution networks separately; and meanwhile, a method for efficiently solving models is provided on the basis of information interaction of the main network and the distribution networks. The influence of the active power regulation capability of the active distribution networks containing energy storage on day-ahead scheduling production is fully considered, global optimization of the whole network can be achieved through the optimized scheduling scheme, the power generation cost of a generator set of the network is reduced to the maximum extent and waste of resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and more specifically relates to a day-ahead dispatching method of a main network considering the active power adjustment capability of an active distribution network. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, the penetration rate of new energy sources such as photovoltaic and wind power in the grid is gradually increasing, especially in the distribution network, the penetration rate of new energy is increasing. At the same time, with the power electronics With the continuous development of technology, more and more energy storage is distributed in the distribution network. The controllable equipment in the original distribution network gradually increases, and gradually becomes an active distribution network with many adjustable and controllable resources. It will have more autonomy and be able to dispatch controllable e...
