Abstract

The invention discloses a stochastic optimization control method and system for the inside of a virtual power plant participating in gas power market. The method comprises the steps that S1 an electric-heating-gas model of the virtual power plant is constructed, and a target benefit function of the electric-heating-gas model is determined; S2 a discretization solution model of a super-quantile isconstructed according to the target benefit function; and S3 the discretization solution model is used as a fitness function to construct an intelligent algorithm model, and a pre-built control schemeis used as the initial input of the intelligent algorithm model to calculate and determine an optimal control scheme under a preset operation scenario. The method has the advantages of strong representativeness, good accuracy and the like.

Description

technical field

[0001] The invention relates to the field of optimization control of virtual power plants, in particular to a method and system for internal random optimization control of virtual power plants participating in the gas-electricity market. Background technique

[0002] When a large number of distributed power sources are connected to the power grid, the fluctuation of their output power will affect the safe, economic and stable operation of the power grid. A virtual power plant (Virtual Power Plant, VPP) can aggregate various distributed resources such as generator sets, energy storage, and controllable loads in terms of electrical characteristics, and participate in grid scheduling and market operations. Coordinated optimization control can reduce the impact of renewable energy output uncertainty.

[0003] At present, most domestic and foreign studies on the economic dispatch of virtual power plants focus on the optimal dispatch of electricity or the coordina...
