Abstract

The invention relates to a virtual power plant optimization establishment method for power grid deep peak regulation auxiliary service, which comprises the following steps of: firstly, randomly generating an initial virtual power plant establishment scheme population by using a genetic algorithm; secondly, simulating each virtual power plant to participate in a peak regulation auxiliary service market based on a typical day scene, solving a clearing result by using a linear programming solver ILOG CPLEX in a unified marginal clearing mode, and calculating a peak regulation income index; then, calculating an electrical distance between nodes of the power distribution network based on power voltage sensitivity to obtain a modularity index reflecting the structural characteristics of the virtual power plant; and finally, establishing a virtual power plant optimization establishment model by taking the maximum value of the weighted sum of the peak regulation income index and the modularity index as a target function, and performing iterative solution by using a genetic algorithm to formulate a virtual power plant optimization establishment scheme. The method provided by the invention solves the problem of aggregation and construction of flexible resources with scattered demand sides and poor direct control performance, and meets the deep peak regulation auxiliary service demand of the power grid.

Description

technical field [0001] The invention relates to the technical field of deep peak shaving auxiliary services, in particular to a method for optimizing the formation of a virtual power plant for the deep peak shaving auxiliary services of power grids. Background technique [0002] With the advent of the "dual-carbon" era, new energy power generation such as wind and solar will develop rapidly, accounting for an increasing proportion, which will cause more serious power grid peaking problems. The development of traditional thermal power will gradually stagnate to decrease, and the source-side deep peak shaving capacity will not increase but decrease. However, demand-side flexible resources such as electric vehicles and energy storage are growing rapidly, and utilizing them to participate in peak shaving can bring huge economic benefits. [0003] As an effective way to aggregate flexible resources on the demand side, virtual power plants (VPP) can achieve energy accumulation an...
