Abstract
With the rapid development of communication technology, the cooperation between electrical systems and other energy systems has become possible to promote wind power accommodation. As a common kind of energy carrier, the water distribution system has not been researched so far to help accommodate wind power when integrated with other energy systems. This paper proposes a novel model of integrated electrical, heating, and water distribution system to accommodate wind power. The optimal scheduling of heat pump and water pump are studied to make full use of the abundant wind power. The heat transmission loss is considered and thus the best siting of the heat pump can be determined. The demand response program is also included in the schedule structure to make the modeling more comprehensive. Moreover, a novel two-layer decentralized optimization algorithm is proposed to protect the data privacy of each energy system. The effectiveness of the proposed integrated system model and the two-layer decentralized algorithm are verified on two test systems. The results indicate that system integrations can reduce the wind power curtailment significantly and decrease the operation cost of each energy system. Besides, the proposed two-layer algorithm performs well in terms of the algorithm efficiency and scalability.
