Abstract

The invention provides a novel demand response method considering an expected kilowatt-hour power curve, and belongs to the technical field of demand response of a power distribution network of a novel power system. High-proportion uncontrollable renewable energy sources are merged into a power system, so that the problem of source-load imbalance is easily caused, and a demand side user needs to be stimulated to participate in renewable energy source consumption. Aiming at the problems that an existing demand response technology based on time-of-use electricity price focuses on energy cost, interaction power fluctuation between a user and a power distribution network cannot be effectively reduced, and meanwhile, the electric energy dispatching flexibility of the user cannot be fully excavated, the invention provides a demand response method considering an expected kilowatt-hour power curve (EKPC) to define the power cost. And friendly interaction between the demand side user and the power distribution network is realized. A mathematical model of an expected kilowatt-hour power curve is constructed through power supply side output conditions, a novel demand response scheduling model is designed to determine an electric energy scheduling scheme, and technical reference is provided for friendly interaction between a power distribution network and users.

Description

technical field [0001] The invention belongs to the technical field of demand response of a novel power system distribution network, and in particular relates to a novel demand response method considering an expected degree electric power curve. Background technique [0002] With the development of low-carbon power systems, renewable energy generation has gradually become one of the important energy productions of new power systems, and the demand response technology of distribution network has become an important method to promote the consumption of renewable energy. In addition, the widespread deployment of distributed energy sources has driven the emergence of microgrids or prosumers. As the penetration of intermittent renewables in microgrids or prosumers continues to increase, the share of renewables on the energy supply side will gradually increase. This shift from fossil fuels to renewables not only reduces the controllability of power sources, but also introduces ad...
