Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to a method for improving energy utilization through interaction between a micro-grid and an electric vehicle V2G. Background technique [0002] At present, with the rapid development of electric vehicles, the demand for power grids or microgrids is gradually increasing. When the power grid or microgrids need power support at certain times, electric vehicles can feed back power to the grid. When the power grid performs energy conversion, there is a problem of energy disappearance, which causes a certain degree of loss of electric energy resources. [0003] The existing method of interaction between microgrid and electric vehicle V2G to improve energy utilization only relies on the microgrid centralized control center to control the output of photovoltaic units and wind power and photovoltaic in the microgrid to control its power generation, increasing the wind power.

[0002] At present, with the rapid development of electric vehicles, the demand for power grids or microgrids is gradually increasing. When the power grid or microgrids need power support at certain times, electric vehicles can feed back power to the grid. When the power grid performs energy conversion, there is a problem of energy disappearance, which causes a certain degree of loss of electric energy resources.

[0003] The existing method of interaction between microgrid and electric vehicle V2G to improve energy utilization only relies on the microgrid centralized control center to control the output of photovoltaic units and wind power and photovoltaic in the microgrid to control its power generation, increasing the wind power. The absorptive capacity of photovoltaics is not conducive to carbon emissions, and it is impossible to accurately predict the power generation and electricity consumption based on the historical use of the micro-grid, which makes the energy storage of the micro-grid insufficient, which affects the living environment of users, and it is impossible to integrate electric power The effective combination of automobiles and micro-grids is not conducive to the energy regulation between grids and reduces the use effect of micro-grids
