Résumé

The fluctuations in renewable energy and user demands introduce compound uncertainties to the operation of integrated energy systems (IESs). Rational energy management involving these uncertainties therefore is of great significance to enhance the renewable energy penetration and efficient energy utilization. This paper developed a novel optimal dispatching strategy for integrated energy systems with ice slurry based cold storage. It features the integration of a robust model and an opportunity model based on information gap decision theory (IGDT) to explore the optimal operation scheduling, while considering the uncertainties from both supply and user sides comprehensively. The adoption of risk-aversion method and risking-seeking method in the proposed strategy was compared, and the optimal dispatching of an IES with and without cold storage was assessed by compared to the IES optimized using conventional deterministic optimization strategy. It was found that the deterministic optimization can reduce the operational cost of the IES to CNY 93.01 a day, however, there was a lack of resilience to even minor uncertainty from the supply and demand sides. Differently, the optimal dispatching strategy adopting risk-aversion method enables the ice slurry based cold storage system maintains a safe uncertainty radius within 0-1.06, whereas the system without ice storage led to a failure when
experienced unbounded radius expansion. Using the strategy adopting the risk-seeking method can further extend the uncertainty radius of the system from 0.58 to 1.38 with the deviation coefficient increasing from 0.4 to 0.9, thereby enhancing the resilience to uncertainties for lower operational cost. The optimal dispatching strategy developed in this study can facilitate the application of IESs with cold storage by promoting the operational flexibility and allowing more attractive economic benefits.
