Problems solved by technology

At present, the coordination and optimization of internal electricity price and distributed photovoltaic power generation and energy dispatching are still not closely combined, especially the lack of a unified coordination and optimization method, resulting in a low participation of electricity price control in distribution network operation control and energy management

Abstract

The invention discloses a coordinated optimization method for the internal electricity price of a micro grid group with high-permeability distributed power supplies, which relates to the technical field of optimal dispatching of distribution networks. The coordinated optimization method includes the following steps: updating internal electricity price information multiple times; obtaining the netload of each micro grid maximizing the economic benefit of the micro grid multiple times according to the grid electricity price information, the internal electricity price information and the economic benefit model of the micro grid; and obtaining the economic benefit of a micro grid operator multiple times according to the grid electricity price information, the internal electricity price information, the net load information and the economic benefit model of the micro grid operator until the optimal economic benefit of the micro grid operator is achieved. The coordinated optimization methodrealizes the coordination among the source/storage/load of the distribution network by taking the internal electricity price as a means of adjustment, so as to maximize the revenue of the micro gridoperator and optimize the revenue of each micro grid.

Description

technical field [0001] The invention relates to the technical field of distribution network optimization dispatching, in particular to a method for coordinating and optimizing the internal electricity price of a micro-grid group containing a high-permeability distributed power supply. Background technique [0002] With the high penetration of massive distributed power sources, the distribution network has changed from a radial network to a network interconnected with power sources and users, and the distribution network has changed from a traditional one-way passive network to a two-way power network. Fluid active network. At present, the coordination and optimization of internal electricity price and distributed photovoltaic power generation and energy dispatching are still not closely combined, especially the lack of a unified coordination and optimization method, resulting in a low degree of participation in electricity price control for distribution network operation con...
