摘要：
Aiming at the problem of new-energy accommodation and low-carbon heating in the energy supply system of countryside, a new method of coordinated heat and power dispatch is proposed, which considers heat balance model of building and flexible indoor comfort constraint of customers. First of all, a flexible indoor comfort constraint based on the schedule of villagers is put forward, and then a heat balance model is established, which considers the building envelope, the penetration of doors and windows, heat consumption of opening doors and windows and the heat dissipation of the internal heat source. Secondly, the basic architecture for the micro-energy network of countryside is constructed, which includes household electric-heating supply system and village-level centralized photovoltaic system. Thirdly, the models of various components in microgrid are developed, such as air source heat pump model. Furthermore, a mathematical model of coordinated heat and power dispatch is established, which considers the economy of the whole system under the indoor comfort constraint. A solution method based on genetic algorithm is proposed. Finally, the validity and practicability of this method is verified by a typical case analysis. © 2019 Automation of Electric Power Systems Press.
