Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a residential electric load power supply device. Background technique [0002] Electricity cannot be stored economically on a large scale, and both the supply and demand sides need to ensure the implementation of balance. These characteristics of the power system require that the power grid must be planned in advance to ensure the reliable operation of the system. Under the traditional power system, when the peak power consumption increases, only by building more The power generation and transmission facilities to meet the electricity demand will not only cause the difference between peak and valley power demand to gradually increase, but will inevitably push up the peak power consumption and the probability of occurrence, and because the capacity increase cycle is shortened, the power consumption will be reduced. Increased costs lead to higher electricity pric...

Problems solved by technology

[0004] Since the objects used in demand response need to be relatively stable and the power consumption needs to be of a certain scale, the current implementation of demand response in practical applications is only for experimental use for enterprises with relatively large power consumption, and for residential electricity demand Response, due to the scattered users and unstable power consumption, the existing demand response solutions for residential electricity use mostly rely on the popularization of smart meters and smart home appliances, but this solution has high costs. , line transformation is difficult, technical complexity and other issues, so it is difficult to be popularized
