A novel optimal dynamic energy flow model of IES in superposition form is developed. Scheduling delay caused by system inertia is solved in a new dispatch framework. Contunous dynamics are factored in rolling optimization with low computing burden. The proposed multi-time scale optimal dynamic scheduling is accurate and efficient.
Addressing these challenges requires advancements in long-duration energy storage systems. Promising approaches include improving technologies such as compressed air energy storage and vanadium redox flow batteries to reduce capacity costs and enhance discharge efficiency.
Therefore, based on the superposition characteristic of the ODEF model, we decompose the base state and each dynamic change generated by decision variables over time. By incorporating these dynamics through superposition before each rolling optimization, our approach ensures the continuous inclusion of dynamics.
