Optimal Operation of Multi-energy Collaborative System Considering Demand Response
2020
In a multi-energy collaborative system, cooling, heating, electricity and other energy sources are coupled and complementary. Through multi-energy coordination and mutual assistance, their operating efficiency and economic benefits can be significantly improved. Demand response as a multi-energy supply-demand balance method can further improve system flexibility and economy, and power demand response as a viable method has been implemented in multiple provinces. In order to clarify the impact of power demand response on the optimal operation mode of multi-energy cooperative system, this paper proposes a multi-energy cooperative system optimized operation model that considers market-based elastic price-type demand response. First, the main components of the multi-energy collaborative system are analyzed. Based on the energy hub model, the multi-energy coupling characteristics are studied, and a price-based demand response model based on market elasticity is constructed. Based on this, the optimization with the lowest daily operating cost of the multi-energy collaborative system is established. Operation model; Finally, combined with actual case calculation analysis, it is verified that the adoption of price-type demand response measures can significantly improve the economy of multi-energy collaborative systems.
