摘要：
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. © 2019, Electrical Technology Press Co.
