Abstract：A optimal dispatching method for regenerative electric heating considering the heating reliability and
capacity of the distribution network is proposed. Firstly, based on the load heat demand, the load models are built,
and the regenerative electric heating equipment and system are modeled. Then, the load capacity model of
distribution network is established. Finally, with the restriction of transmission power of distribution network and
heating reliability, an optimal dispatching method of regenerative electric heating considering the heating
reliability and capacity of the distribution network is proposed. In order to minimize the daily operation cost and
the deviation degree of the distributed load, the optimal scheduling scheme of the electric heating system is
results show that the proposed method can make the best of the heat storage of regenerative
electric heating under the power constraints of distribution network.
