摘要：
An operation optimization model considering static security and optimal energy flow is proposed for district power-heating integrated energy systems (IES) with multiple energy hubs (EH). Firstly, a calculation method for optimal energy flow is proposed. Then a static security assessment index is established based on energy flow. Overall IES operating cost and static security are both taken into account in the upper-level of the model to optimize power-heating output of each EH. After obtaining multi-objective optimal power-heating flow distribution of IES, the lower-level of the model takes both economic index and photovoltaic accommodation capacity as target to optimize the output of each unit in EHs. Finally, a case study is given to verify effectiveness of the proposed model. © 2019, Power System Technology Press. All right reserved.
