In order to solve the problems of unqualified power supply voltage and poor power flow distribution in distribution network, a PCMTESS(Phase Change MaTerial Energy Storage System) demand response based economic dispatch strategy of distribution network is proposed. The structure and working mechanism of PCMTESS are introduced, the energy consumption law of thermal side is analyzed. The encapsulation model of thermal side considering heat dissipation and the encapsulation model of power side considering reactive power regulation capability are established. On this basis, considering the power flow distribution constraints and the output characteristics of distributed new energy, aiming at the minimum power purchase cost of distribution network, a unified dispatch model of distribution network is established considering the uncertainties of photovoltaic, wind turbine and load. The interactive iterative solution strategy is proposed to realize the efficient solution of the optimization model. Simulative results of IEEE 41-bus distribution network show that the proposed PCMTESS can optimize the power flow distribution of distribution network and improve the power quality of the power grid under the premise of maintaining room temperature comfort. The proposed dispatch model provides a new perspective for the safe and economical dispatch of distribution network and the comprehensive energy consumption.
