Abstract:

In order to facilitate the complementary coupling of various forms of energy and achieve local consumption of renewable energy, integrated energy system (IES) has become a research hotspot across multiple disciplines. Considering the diversity and complexity of energy devices and networks, as well as the disparity in energy time scales, the source, grid and load with adjustable characteristics within the system are modeled as storage elements using energy balance principles, and a virtual energy storage system is constructed with them, which is incorporated into the optimization and scheduling of the IES. To accurately grasp the research focus of virtual energy storage, this paper firstly introduces the definition, logical structure and technical connotation of virtual energy storage, and summarizes four virtual energy storage modeling methods and characteristic indexes for the equipment or network on the source, grid and load side of integrated energy system, and then emphatically analyzes the specific application of virtual energy storage in four typical scenarios, and finally looks ahead to the future development direction of virtual energy storage.
