Abstract

The invention discloses an electric power demand side responding method with multiple time scales. First of all, through advanced measurement and an intelligent algorithm, parameters are detected and analyzed, wherein the parameters include a load group electricity utilization correlation degree, time-of-use electricity prices and a photovoltaic power generation output; and then based on the detected parameters, at the multiple time scales, for load groups including smart home appliances and electric car loads, prevention control strategies and emergency control strategies are established; real-time demand response measures and current electricity load scheduling measures are respectively established to achieve the local power consumption of photovoltaic power consumption. The electric power demand lateral responding method of the invention realizes peak regulation demands and consumption of a photovoltaic power of a power grid on the basis of a plurality of parameters.

Description

technical field [0001] The invention belongs to the smart grid technology, and in particular relates to a multi-time scale power demand side response method. Background technique [0002] Demand response (DR) is developed from demand side management (DSM) on the basis of electricity marketization. Traditional power demand side response technologies are mainly divided into two categories: price-based mechanism and incentive-based mechanism. Price-based demand response refers to the rational arrangement of user electricity consumption through time-varying electricity prices. At this stage, it is mainly divided into three categories: Time of Use Pricing (TOU), Real Time Pricing (RTP) and peak electricity price ( Critical Peak Pricing, CPP), time-of-use electricity price participates in the month-ahead scheduling where the electricity price is fixed for a period of time; real-time electricity price participates in day-ahead scheduling and intraday scheduling that requires a hig...
