Abstract

The invention discloses a transmission and distribution coordinated dispatching target cascaded analysis method of a high-proportion renewable energy source power system. The transmission and distribution coordinated dispatching target cascaded analysis method of the high-proportion renewable energy source power system comprises a local scheduling layer which is a scheduling unit for performing joint output optimization on a distributed renewable energy source in the interior of one power distribution network; a power transmission network and a power distribution network which separately serves as autonomous main bodies for decoupling through border frequency and optimizing resources in zones separately and cooperating with each other to schedule a power transmission plan, wherein a powertransmission network scheduling layer is to perform uncertainty modeling on the renewable energy source based on the improved interval optimization method to construct an energy and standby coordinative optimization model, and the power distribution network scheduling layer is a local scheduling layer set for the distributed renewable energy sources and performs joint output optimization by utilizing a scene method and combining with an energy storage system, thereby constructing the distribution network layer sub-problems into a dynamic economic scheduling model with optimal economical efficiency and with a target of absorbing the distributed renewable energy source joint output in the local scheduling layer.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a cascading analysis method for transmission and distribution coordination and scheduling targets of high-proportion renewable energy power systems. Background technique [0002] With a large number of distributed power sources connected to the power distribution system, the operation of the distribution network presents a more flexible and changeable trend, and the traditional distribution network is gradually transformed into an "active distribution network" (Active Distribution Network, ADN). The interaction between the Internet is getting closer and closer. At the same time, the proportion of wind power and other renewable energy in the power grid is increasing, and both centralized and distributed renewable energy are facing difficulties in consumption. Under the new situation, the dispatching of the high-proportion renewable energy grid will shift from the regulation f...
