Problems solved by technology

In the existing tidal power generation projects, the microgrid has not established an effective optimal dispatching model, which takes wind energy and solar energy into account in the scheduling of island microgrids, but does not consider the integration of tidal power generation into island microgrids, nor does it Taking time-of-use electricity prices into account specifically in the dispatch of island microgrids leads to uneconomical power generation systems and high operating costs

Abstract

The invention discloses an island micro-grid operation optimization method based on time-of-use electricity price, and belongs to the field of power grid dispatching. According to the method, the time-of-use electricity price is added into the island micro-grid for modeling, the established model is solved by using the improved PSO algorithm added with the inertia weight coefficient, the method has relatively high optimization capacity, is simple and universal, is high in robustness, high in precision and fast in convergence, has very high superiority in solving the micro-grid optimization scheduling problem, the algorithm is prevented from falling into local optimum, the calculation precision is improved, the finally obtained optimization scheme can make each power generation system operate economically, and the operation cost is reduced.

Description

technical field [0001] The invention belongs to the field of power grid dispatching, and in particular relates to an operation optimization method of an island micro-grid based on a time-of-use electricity price. Background technique [0002] With the continuous improvement of my country's marine strategy, the marine economy has entered a stage of rapid development, and the enthusiasm of the whole society for the development of islands is increasing. However, energy resources are very important to the development of islands, which determine the sustainable development of all aspects of islands. Directly Affect the competitiveness of the main industries of the island; the development of the island area is inseparable from reliable power supply, but due to the special geographical environment of the island area, it is difficult to get a good guarantee for its power supply, and the island's energy supply is too dependent on external input Conventional energy sources make it diffi...
