摘要
安全可靠是综合能源系统的基本要求,为保障综合能源系统的供能可靠性,开展其风险评估研究具有十分重要的意义。文章首先建立考虑蒸汽网络的电热耦合潮流计算算法,接着设计考虑运行侧与用户侧的综合能源系统风险评估指标体系,最后提出基于电热耦合潮流的综合能源系统风险评估流程。算例结果表明,文章所提出的风险评估指标及分析方法可以有效识别多能流系统的整体风险。
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.
