The invention relates to the field of new energy optimization scheduling, and provides a virtual power plant output coordination game method integrating light, storage and combustion and terminal equipment, and the method comprises the steps: constructing two or more than two virtual power plants and an energy storage coordination controller model of each virtual power plant; the virtual power plant comprises a photovoltaic power generation model, an energy storage power generation model and a micro gas turbine power generation model; obtaining the interactive electric quantity of the energy storage coordination controller model of each virtual power plant, and establishing a target function for maximizing the revenue of each virtual power plant; constructing a non-cooperative game model of the virtual power plant based on the objective function; and optimizing the non-cooperative game model by taking the interactive electric quantity of the energy storage coordination controller of each virtual power plant as a game strategy to obtain the optimal coordination power among the virtual power plants. According to the method, the optimal coordinated output among the virtual power plants is realized through the energy storage coordination controller model and the non-cooperative game algorithm, so that the stability, the yield rate and the energy utilization rate of each virtual power plant are improved.

Description

technical field [0001] The invention belongs to the technical field of optimal scheduling of new energy sources, and in particular relates to a virtual power plant output coordination game method integrating solar energy storage and combustion, a terminal and terminal equipment. Background technique [0002] Under the energy transformation and "carbon neutral" strategy, wind energy, solar energy and other renewable energy with random, intermittent, and fluctuating characteristics are connected to the distribution network on a large scale and in a high proportion, so that the large-scale production of existing energy and electricity and the long-distance Distance transmission is gradually shifting to distributed / centralized production and utilization. Due to the small capacity of grid-connected units, strong output fluctuations, and relatively dispersed geographical locations of renewable energy, it has brought huge pressure on the power grid for peak regulation and frequency...

In the prior art, the document "Multi-time-scale Coordinated and Optimal Scheduling of Multiple Virtual Power Plants under the Permeation of High Proportion of Renewable Energy" (Yang Hongchao et al., School of Economics and Management, Changsha University of Science and Technology) published in April 2020 combines multi-time-scale optimization and coordination The optimal scheduling strategy is applied to the optimal scheduling of multiple virtual power plants to achieve hour-level and minute-level time scale optimization, eliminate the impact of randomness and disturbance in the system, and realize the safe consumption of a high proportion of renewable energy. At the same time, a risk characterization of the profit function is proposed In order to describe the influence of uncertainty, each virtual power plant in this literature only interacts with the power distribution network. Although it can minimize the cost of each virtual power plant to a certain extent, it does not consider the power interaction between virtual power plants from the global perspective. Up-consumption of new energy to maximize the revenue of each virtual power plant
