PROCEEDINGS OF 2019 IEEE 3RD INTERNATIONAL ELECTRICAL AND ENERGY CONFERENCE (CIEEC)(2019)
摘要
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.
