technical field [0001] The invention relates to the technical field of integrated energy system scheduling, in particular to a combined heat and power optimal scheduling method oriented to integral central heating and demand response. Background technique [0002] It is an effective means to realize a high proportion of new energy consumption by coupling electricity / gas / heat multiple types of energy to construct an Integrated Energy System (IES) and performing coordinated scheduling. However, there are significant differences in response time characteristics and transport characteristics during operation of multi-heterogeneous energy and multi-type networks, which bring many challenges to the coordinated operation of integrated energy systems. [0003] In the combined heat and power system, electric energy is easy to transmit and difficult to store, while thermal energy benefits from the characteristics of large energy inertia and has good energy storage benefits. In this r...
