Example Embodiment

[0054] The invention discloses a method for coordination and optimization of a wind power supplier and an electric vehicle replacement station based on a master-slave game, which includes the following steps:

[0055] In step (1), the wind power supplier signs a cooperation agreement with the electric vehicle swap station, stipulating that the electric vehicle swap station can only use wind power for charging, and at the same time, the electric vehicle swap station can also sell the stored excess power to the wind power supplier;

[0056] Step (2): After obtaining the next day’s on-grid electricity price from the distribution network operator, the wind power supplier takes the charging and discharging price of the electric vehicle replacement station as the decision variable to build a wind power supplier’s price optimization model to guide the price of the electric vehicle replacement station. charging and discharging decisions;

[0057] Step (3), after the electric vehicle s...

Abstract

The invention discloses a coordination optimization method of wind power merchant and electric vehicle substation based on master-slave game, comprising the following steps: (1) signing a cooperationagreement between wind power merchant and electric vehicle substation; (2) after the wind power merchant obtains the on-grid electricity price of the next day from the distribution network operator, taking the charge and discharge price of the electric vehicle substation of the next day as a decision variable, constructing a price optimization model of the wind power merchant; (3) after obtainingthe charge/discharge price of the next day, taking the charge/discharge power of the next day as a decision variable to construct a charge/discharge power decision model of the electric vehicle substation; 4, modeling the optimization process of wind power merchant and the electric vehicle substation as the decision makers with different positions for the dynamic game for as the master-slave gamemodel. By using the coordinated optimization method proposed by the invention, the anti-peak regulation characteristic of the wind power is weakened, and the profits of the wind power merchant and theelectric vehicle substation are increased.

Description

technical field [0001] The invention relates to a method in the field of power system dispatching operation, in particular to a method for coordination and optimization of a wind power supplier and an electric vehicle replacement station based on game theory. Background technique [0002] The development and utilization of wind power plays a positive role in alleviating the energy crisis and reducing environmental pollution caused by fossil energy consumption. China's installed capacity of wind power has surpassed that of the United States, becoming the world's largest installed capacity of wind power. However, with the rapid development of wind power, its anti-peaking characteristics and uncontrollability have brought a huge impact on the power grid. In order to effectively suppress the impact of wind power grid-connected on the grid, researchers proposed to build energy storage power stations for wind power to improve the controllability of wind power and suppress its ant...
