Load Allocation Method Based on Fairness and Economy in Hierarchical and District Demand Response

Abstract

This paper proposes a delaminating and districting demand response load fair and economical distribution method. The main methods are as follows: firstly, according to the power supply area and voltage level where the load is located, the vertical correspondence between users, distribution transformers, lines and substations is sorted out, and user attribute files are established to form a delaminating and districting load resource pool; then, based on load resource pool and power grid regulation demand, a comprehensive objective function considering user credit rating and regulation cost is established, and constraints such as regulation demand, recovery time, duration and regulation range are introduced to form a demand response load distribution model. Finally, the mixed integer programming technology is used to solve the model, so as to obtain the load demand response scheme that meets the principle of fair and economic distribution. Example test results verify the correctness and effectiveness of this method.
