Optimal operation of integrated electricity and heat system: A review of modeling and solution methods

Abstract The optimal operation of the integrated electricity and heat systems (IEHS) can bring environmental benefits, reduce operational cost, achieve high penetration levels renewables. This review aims to provide a comprehensive overview IEHS modeling solution methods for operation. With respect operation, is reviewed from five aspects, including representation dynamic characteristics, flexibility improvement, under uncertainty, joint dispatch electrical power system (EPS) district heating (DHS), market clearing EPS DHS. are divided in four groups according properties optimization problems, i.e., energy flow calculation, decentralized optimization, using relaxation convexification techniques, based on intelligent algorithms. main advantages, limitations detailed compared. In end, current gaps future research summarized regarding IEHS.
