With the promotion of clean heating units such as combined heating and power(CHP)units

electric boilers(EB)and so on

the interaction between electric distribution network(EDN)and the district heating system(DHS)is becoming more and more close. Considering the increasing penetration of distributed renewable energy power generation

an optimal day-ahead dispatch strategy of regional electricity-heating integrated systems with the constraints from the unbalanced three-phase electric distribution network

regional energy stations and the district heating network

is proposed from the perspective of the coordination of multiple energy stations. Furthermore

the benefit of this strategy on wind power accommodation is analyzed. Finally

the results under three different scenarios show that the proposed optimal dispatch strategy can take full advantage of multi-energy complementary

improve the consumption rate of wind power

and effectively reduce the losses in EDN and the operation cost of regional energy stations to achieve economic goals.
