摘要：
The ever-increasing proportion of clean energy sources adds the uncertainties and space-time distribution factors to the integrated energy system (IES) making the modeling and optimal dispatching of IES faced with great challenges. Aiming to these problems, an off-design model which reflects the nonlinear relation between efficiency and load rate is established first based on the internal energy flow model. Considering the flexible load characteristics, a demand-side management strategy is applied to encouraging the users to participate in the dispatching by optimizing the energy prices and the period division. Finally, a multi-objective optimization model and a bi-level hierarchy optimal strategy are proposed, on whose basis the multi-objective problem is solved by the intelligent optimization algorithm. The simulation is carried out based on the typical daily load and meteorological data of an IES park, and the results show that the proposed method can promote the positive source-load interaction, mobilize the enthusiasm of supply and demand sides. The economy, environmental protection and stability of the system operation are enhanced without affecting the comfort of energy consumption. © 2022 Power System Technology Press.
