Considering the influence of external energy supply conditions and energy equipment on the integrated energy system, a multi energy complementary scheduling simulation based on hybrid power flow algorithm is proposed in order to reduce the complexity of multi energy coupled power flow calculation and improve the operability of engineering application,. The constraints of output capacity of energy conversion hub, coupling of multi energy flow, energy supply balance and equipment operation were set up. The multi-objective optimal hybrid power flow computing platform and non-inferior sequencing genetic algorithm were applied to solve the optimization model of multi-energy complementary scheduling. The optimal solution was used to realize the multi energy complementary scheduling of hybrid power flow algorithm. The simulation results show that the method has the advantages of improving economy and static security, and can effectively realize the multi energy complementary scheduling of the integrated energy system.
