Abstract

The invention discloses a Nash game-based microgrid voltage regulation method and apparatus. The method comprises the steps of establishing a voltage regulation game model of a microgrid participator;establishing strategy space of participators, wherein the strategy space of each participator comprises a decision variable and a constraint condition; determining the strategy space according to electricity prices and smooth and steady conditions; determining a system benefit function and a constraint condition of the voltage regulation game model; judging whether to execute Nash balance or not;if not, returning to the step 3; and if so, converting the voltage regulation game model into a dual-layer optimization model and performing solving. By virtue of the Nash game-based microgrid voltage regulation method and apparatus, the maximum of the system comprehensive benefit under access of the multiple distributed generations can be realized.

Description

technical field [0001] The invention belongs to the technical field of electric power system reliability, and in particular relates to a method and device for adjusting the voltage of a microgrid based on a Nash game. Background technique [0002] Renewable and sustainable technologies play a key role in my country's energy conservation and emission reduction policies. In the context of large-scale wind power being continuously connected to the grid, China is vigorously promoting the development of various distributed power sources, striving to connect more green and sustainable distributed energy sources to the grid. However, connecting too many DGs may bring severe challenges to the safe and stable operation of the distribution network. Therefore, the researchers proposed a micro grid (micro grid, MG). The microgrid can integrate some small-scale DGs into the large grid to meet the future development needs of the grid. However, due to capacity constraints, in most elect...
