摘要：
Under the background of the carbon peaking and carbon neutrality goals, the massive increase for the renewable energy integration puts forward new requirements for the ability of the flexible operation of the regional integrated energy systems (RIES). In order to effectively tap the potential of the system flexibility resources, and based on a refined model of the heat network and heat load, this paper proposes a multi-objective optimization strategy of the RIES considering multi-energy flexible resources. Firstly, to accurately describe the dynamic process of the heat energy transmission, a heating system refined transmission model and a building energy storage characteristics model are established. Secondly, a multi-energy flexible resource model is built to quantitatively analyze the adjustable capacity of the thermal units. Then, a RIES model considering the multi-energy power flow is erected. And a day-ahead scheduling strategy with the objective functions of the lack of operation flexibility and comprehensive operation cost is proposed. The case study shows that the presented multi-energy flexible resource model and the multi-objective scheduling strategy is able to effectively reduce the comprehensive operation costs and improve the renewable energy consumption rate. As a result, the pressure on the energy supply during the peak period is effectively relieved. © 2023 Power System Technology Press. All rights reserved.
