Description

technical field [0001] The invention belongs to the technical field of new energy optimization scheduling, and in particular relates to a virtual power plant output coordination game method, terminal and terminal equipment integrating light storage and combustion. Background technique [0002] Under the energy transition and the "carbon neutrality" strategy, renewable energy sources such as wind energy and solar energy with random, intermittent, and fluctuating characteristics are connected to the distribution network on a large scale and at a high rate, enabling the large-scale production of existing energy and electricity and remote Distance transmission is gradually shifting towards distributed / centralized production and utilization. Due to the problems of small capacity of grid-connected units, strong output volatility, and relatively scattered geographical locations, renewable energy has brought huge pressure on peak regulation and frequency regulation to the power grid...

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
