Cooperative optimization of power system based on demand response

In the power system, various energy sources such as cooling, heating, and electricity are coupled and complementary. As a multi-energy supply and demand balance method, power demand response can further improve the flexibility and economy of the system. In order to clarify the influence of demand response on the optimal operation mode of multi-energy cooperative system, this paper proposes an optimal operation model of multi-energy cooperative system based on market-elastic price demand response. Firstly, the main body of the multi-energy cooperative system is analyzed, the multi-energy coupling characteristics are studied based on the energy hub model, and a price-based demand response model based on market elasticity is constructed. Secondly, the optimal operation model aiming at the lowest daily operating cost of the multi-energy cooperative system is established. Finally, combined with the calculation and analysis of actual cases, it is verified that the adoption of price-based demand response measures can significantly improve the economy of the power multi-energy collaborative system.
