Description

technical field [0001] The present invention relates to the technical field of electric power dispatching, in particular to an electric-heat joint dispatching method and system considering comprehensive demand response. Background technique [0002] In recent years, with the rapid development of the economy, the high-speed and rough energy utilization methods have gradually deepened the contradiction between energy consumption and environmental protection. Seeking a safe, efficient, low-carbon and clean energy operation model, breaking the technical barriers of the existing energy supply system, has become the focus of attention of countries all over the world, coupling multiple energy systems such as electricity, natural gas, heating, transportation, etc., to achieve high efficiency in different energy levels The integrated energy system utilized has become a research hotspot. [0003] In order to realize the efficient operation of the integrated energy system, it is neces...

AI Technical Summary

Problems solved by technology

[0005] The existing dispatching methods mostly respond to a single power demand, without considering the internal energy substitution of users, and have problems such as small demand elasticity, poor regulation effect, difficulty in large-scale consumption of renewable energy, and failure to realize an integrated energy system. Optimal operation and other issues

Since most of the existing electric-heat joint scheduling methods only constrain the heat consumption, the factor that directly affects the user's energy consumption experience is ignored. The indoor ambient temperature is understandable. The dynamic process of the role should be taken into account in the scheduling method
