doi:10.3969/j.issn.1000-7229.2019.04.011

Abstract

Abstract: With the continuous growth of multi-type loads such as electric heating in the power grid， traditional single-scheduled means such as electric load demand response or network reconstruction cannot meet the demand of safe and economic operation of the distribution network. A reliable economic dispatching method for distribution network with the combined demand response of end users is proposed. Firstly， the electric load demand response model considering user's responsiveness and satisfaction is constructed. Secondly， the output model of different components in the power-heat coupling system is constructed， and the heat load demand response strategy based on peak and valley electricity price is proposed. With the goal of minimum distribution network operation cost， the safe economic dispatch model of distribution network with multi-period network reconstruction and power-heat comprehensive demand response is co-ordinated. Finally， the validity and practicability of the proposed model and method are verified by an example.

Key words: power-heat combined system, demand response, distribution network reconfiguration, economic dispatch
