Coordinated scheduling of electricity–heat–gas integrated energy system considering emerging energy conversion technologies

Abstract

Couplings between electricity, heat, and natural gas system are deepening due to the requirement of a new energy paradigm and the development and commercialization of emerging energy conversion technologies such as heat pump (HP) and power-to-gas (P2G). In this context, this paper proposed a coordinated scheduling model for a heat–gas–electricity integrated system with compound emerging energy conversion technologies. First, new emerging/growing energy conversion technologies are reviewed and their models are discussed. Secondly, a coordinated scheduling model of the heat–gas–electricity integrated system is proposed with respect to their characteristics and interactions. Finally, an integrated electricity–gas–heat distributed energy system is employed to validate the proposed model. The utilization efficiency and installation suggestion are discussed as well.
