Discussion on Optimal Planning and Operation Framework for Integrated Energy System

Comprehensive and optimal utilization of electricity,thermal energy and gas is a significant w ay to enhance the utilization efficiency of energy and achieve energy sustainable development. How ever,the research of integrated energy system just has been started. There are many w orks needed to accomplish for the establishment of a mature integrated energy system. At the beginning of the study,one of key and necessary basic w orks is to clarify the research ideas and content. This paper expounded the constitutions of integrated energy system,analyzed its advantages,proposed a framew ork of optimal planning and operation for integrated energy system,and discussed the key technologies needed to be solved for establishing integrated energy system,w hich could provide references for the study and implementation of integrated energy system.
