Study on Multi-energy Complementary Model of Coupling System of Distribution Network and Heat Pump Energy Storage

With the continuous integration of cold, heat, electricity and other energy systems and the market-oriented reform of energy transactions, the traditional power demand response can no longer meet the business needs of multi-energy coupling. Distribution network and heat pump energy storage coupled cooling and heating system is a combination of renewable energy utilization and energy storage technology, which is beneficial to improve the utilization rate of renewable energy. At the same time, by shifting peaks and filling valleys, the operating cost of the system can be reduced and the balanced dispatching of the power grid can be realized. In this paper, an electro-thermal complementary model of coupled heating and cooling system with energy storage of distribution network and heat pump is proposed, and through simulation analysis of an example, it is verified that the proposed method can effectively improve the flexibility of energy supply and operation economy of the system.
