摘要 由电力系统、天然气系统和热力系统耦合构成的综合能源系统(IES)是“能源互联网”的重要组成部分,是构建更加经济、环保、高效能源系统的必经之路。该文提出了一种计及相关性的电-气-热IES概率最优能量流计算方法。首先,以IES运行成本为优化目标,综合考虑电力系统、天然气系统、热力系统的运行约束及能量耦合约束,建立了IES最优能量流模型;针对IES中风电接入背景下的不确定性因素,并考虑其相关性,建立IES概率最优能量流模型,并采用基于Nataf变换的三点估计法对该模型进行求解。对由修改的IEEE 24节点电力系统、比利时20节点天然气系统和巴里岛32节点热力系统构成的IES进行仿真分析,仿真结果验证了该文所建立模型的可行性与有效性。

Abstract:The integrated energy system, which consists of the coupling and interactions among electric power system, natural gas system and heating power system, plays an important part in “Energy Internet”. A probabilistic optimal energy flow of electricity-gas-heat integrated energy system considering correlation is proposed. Firstly, considering the operation constraints of electric power system, natural gas system, heating power system and energy coupling constraints in IES, an optimal energy flow is proposed with minimized total cost as the objective. Considering the uncertain and correlated variables, a probabilistic optimal energy flow model is proposed, and three point estimate method based on Nataf transformation is adopted to solve the model. Finally, the model is verified on a IES consisting of modified IEEE 24-bus power system, Belgian 20-bus natural gas system and Barry island 32-bus heating power system.
