Problems solved by technology
[0003] First of all, the battery capacity of electric vehicles is relatively large. If a large number of electric vehicles are charged at the same time, it will have a huge load impact on the power grid and affect the peak-valley balance of the power grid.
Second, in order to meet the load demand of these electric vehicles charging at any time, the grid needs to add more power generation capacity, which will increase the operating cost of the grid
Thirdly, for electric vehicle users, if they still adopt the simple charging method of charging as they use, this will cause higher charging costs for car owners

The method is suitable for being applied as an optimization method for combined auxiliary peak regulation.
Description
technical field [0001] The invention belongs to the field of power grid peak regulation, and relates to an optimization method for assisting peak regulation by utilizing an electric vehicle and a thermal storage electric boiler. Background technique [0002] With the increase of industrial and domestic electricity consumption, the load curve of the power grid fluctuates more violently. For the peak load of the system, peak-shaving resources are not limited to power supply-side resources, and demand-side resources can also assume the role of important peak-shaving resources. Therefore, electric vehicles and heat storage electric boilers can be considered as controllable loads to participate in grid peak regulation. [0003] First of all, the on-board batteries of electric vehicles have a large capacity. If a large number of electric vehicles are charged at the same time, it will have a huge load impact on the power grid and affect the peak-valley balance of the power grid. S...
