Abstract The multi-energy synergy makes the operation of the distribution systems more flexible, which provides a new idea for the distribution systems restoration. This paper proposed an active splitting control strategy for the distribution systems via the multi-energy synergy. A multi-energy flow network model of electric-gas-thermal integrated energy systems is formulated. Then, the active splitting alternative control and coordination control strategies for distribution systems are proposed considering the multi-energy synergy which includes load transfer of energy consumption type and power generation support. Further, an active splitting model of distribution network coupled multi-energy is developed with the reasonable control strategy and distribution system topology to restore more loads and higher load matching with regard of the load priority and controllability. And then, the active splitting strategy is solved by using the greedy algorithm (GA). The proposed method is evaluated by a distribution system coupled with heat and natural gas network, which comprise PG&E 69 distribution system, 32-node heat network and 11-node natural gas network. The results demonstrate the proposed active splitting strategy can significantly restore more loads of the distribution systems with taking into account of the multi-energy synergy.

Key words： Distribution network integrated energy system active splitting multi-energy synergy greedy algorithm
