Renewable energy power station shared energy storage capacity planning method and device

Abstract

The invention provides a renewable energy power station shared energy storage capacity planning method and device, and the method comprises the steps: building an operation model of a shared energy storage system, and enabling the operation model to represent the relation among each participant, a load side and a power grid side in a set alliance mode; determining a system total income scheme in a set alliance mode according to the operation model; iteratively optimizing the income of each participant according to the total income scheme of the system based on a double-layer game theory to obtain an optimal income distribution scheme of each participant; and performing iterative optimization on the energy storage capacity of each participant according to the optimal income distribution scheme to obtain an optimal energy storage capacity planning scheme of each participant. An optimization method is utilized to plan the energy storage capacity scheduling problem of each participant at each moment, so that the benefit of each participant is maximized under the operation mode, and the operation condition of the power system is improved.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a method and device for planning shared energy storage capacity of a renewable energy power station. Background technique [0002] In recent years, due to the concern of environmental issues, various power generation technologies based on renewable energy have flourished, and the installed capacity of renewable energy has taken an increasing proportion in traditional power generation systems. However, the main problem with large-scale integration of wind and solar energy is its inherent characteristics, such as variability, intermittency, and uncertainty, which can have a significant impact on the reliability and efficiency of power system operation. The cooperation of multiple renewable energy sources provides a solution to the variability of renewable energy sources, and wind and solar energy can complement each other in time and area. In addition, considering the cooperat...
