Reliability modeling for Integrated Community Energy System considering dynamic process of thermal loads

Abstract

The Integrated Community Energy System (ICES) has developed rapidly, but the reliability assessment models of ICES are somehow out of date. A new reliability assessment model for ICES is proposed incorporating electricity, gas and heat, considering dynamic process of thermal loads. First, the static model of ICES consisting of three subsystems is constructed based on the energy hub model. Then the inertial features of loads are incorporated in the reliability of ICES. Thereafter, a quasi‐sequential simulation based on a decomposed optimisation method is proposed to assess the reliability of ICES. Case studies are conducted on an ICES with four energy hubs to validate the performance of the presented model. Results show that the proposed reliability assessment model is more practical and the identified weak points of each subsystem have changed after utilising the new model.
