A Novel Multi-Scenario Operation Strategy of Park-Level Integrated Energy System

With the rapid development of communication systems, the traditional energy system has gradually included electricity, gas and heat and expanded to an integrated energy system (IES). This paper presents a multi-scenario operation strategy that considers costs and carbon emissions for a park-level IES. First, simplified models of plants are established based on their operating characteristics. Then according to the connection of different plants of the park, a system-level model of the integrated energy system is built. The multi-scenario operation of the park is achieved through a predefined scenario weight matrix and the improved hierarchical analysis. Finally, the proposed strategy is validated by case studies to be able to effectively allocate the error power of the park and to improve the flexibility of the park's energy supply.
