Research On Local Optimal Dispatching Method Of Park-Level Integrated Energy System

In order to realize the complementary coordination among different energy forms such as electricity, gas, cold and heat in the park-level integrated energy system, and improve the economic benefits of its operation, a typical energy hub structure which takes combined heat and power unit as the core and integrates multi-coupling devices is proposed. By minimizing the daily operating cost, the day-ahead dispatching model of the internal energy flow distribution of the park-level integrated energy system is established and solved by chaotic particle swarm optimization algorithm. The case study verifies the effectiveness of the algorithm, and the established day-ahead dispatching model can flexibly adjust the internal energy flow according to load and the change of time-of-use electricity price, and distribute the output of various devices, which can improve the economic benefits of multi-energy supply, complementary and coordinated operation in the park-level integrated energy system.
