Distributed power supply-oriented virtual power plant operation scheme optimization method

Abstract

The invention relates to a distributed power supply-oriented virtual power plant operation scheme optimization method, and the method comprises the following steps of 1) determining the indexes for comprehensive benefit evaluation, and establishing a comprehensive evaluation index set for virtual power plant optimization operation; 2) considering the difference between the dimension and the numerical magnitude order of each comprehensive benefit evaluation index, and carrying out normalization processing on each index; 3) converting the qualitative comprehensive benefit of a virtual power plant into a quantitative evaluation value by adopting a comprehensive weight determined by a G1-expert clustering weighting method, and establishing a comprehensive benefit evaluation system of the virtual power plant; and 4) performing comprehensive benefit evaluation on the given operation schemes of the plurality of virtual power plants by adopting the comprehensive benefit evaluation system of the virtual power plants, and determining the scheme with the best comprehensive benefit as the optimal operation scheme. Compared with the prior art, the method has the advantages of high feasibility, rapidness, reliability, wide application range and the like.

Description

technical field [0001] The invention relates to the field of optimal operation of a virtual power plant, in particular to a method for optimizing an operation scheme of a virtual power plant oriented to distributed power sources. Background technique [0002] A virtual power plant is a special type of power plant composed of different types of distributed energy sources, and it is also a comprehensive energy management system. The virtual power plant aggregates distributed energy sources such as distributed power sources, energy storage equipment, and electric vehicles through advanced communication technology and software systems, and participates in the operation of the power market and power system. After the virtual power plant is put into actual operation, it can make full use of renewable energy and generate higher income. The comprehensive benefits of virtual power plants are reflected in both technical and economical aspects. Therefore, how to optimize the operatio...

Problems solved by technology

Some literatures have established virtual power plant optimization models with wind-storage storage, and compared the economic benefits of different optimization schemes; some literatures have considered demand response in virtual power plants, established corresponding optimization models, and compared the economic benefits of different optimization schemes. In order to illustrate the economy of the established model; however, the above literature does not consider the contribution of the virtual power plant in the consumption of renewable energy. At the same time, the optimal operation plan of the virtual power plant also needs to consider whether it can meet the dispatch needs and the impact on the environment, it is not comprehensive and in-depth to only consider its economic benefits

Most of the existing literature regards economic benefits as the criterion for evaluating the optimal operation scheme of virtual power plants, but there are few evaluations of technical benefits, and further exploration is still needed
