Description
技术领域 technical field

At present, the grid side mainly compensates for the randomness of new energy power generation through hydropower, thermal power and other conventional generators. This method of regulation only from the power generation side is not economical; at present, domestic scholars have proposed demand-side response, that is, through There are advantages to using price signals or incentives to guide power users to transfer loads, but due to the randomness of electricity prices and user response behaviors, the results of demand response are often uncertain. At present, as a large number of energy storage devices, distributed power sources, electric vehicles, etc. are connected to the grid, and the proportion of household loads is gradually increasing, the types of loads that can participate in grid dispatching are increasing; Connect to the Internet in a way, and then use the advantages of the Internet to measure, control and intelligently manage the dispatchable load.
