Review on planning and operation research of park energy internet

Abstract

As a coordinated and complementary "generation-grid-load-storage-charging" energy system, park energy internet has the characteristics of multi-energy coupling and complementing, which contributes to the reduction of social energy costs as well as the improvement of energy efficiency. Firstly, the connotation and structural division of park energy internet are expounded. On this basis, the power balance model and power flow model of electricity-gas-heat network are discussed. Secondly, the research status of the park energy internet is reviewed from aspects of equipment planning, multi-energy flow optimal scheduling, load-side multi-type response and optimal scheduling considering energy storage. At last, the issues to be further studied are proposed, and the prospects of broad planning, intelligent optimization and interactive market of park energy internet are analyzed, so as to provide references for the future planning and operation research of park energy internet.
