Abstract

Abstract: Security and reliability are the basic requirements of integrated energy systems（IES）. To ensure the reliability of energy supply of IES, it is of great significance to carry out risk assessment research. In this paper, the electricity-heat coupled power flow calculation algorithm considering steam network is established firstly. Then the IES risk assessment indicator system considering operation side and user side is designed. Finally, the risk assessment process based on electricity-heat coupled power flow for integrated energy system is proposed. The results of the test case show that the risk assessment indicators and analysis methods proposed in this paper can effectively identify the overall risk of the multi-energy flow system.

Key words: integrated energy system, risk assessment, electricity-heat coupled power flow, reliability assessment, steam network
