Abstract:

A single energy storage technology cannot meet high-quality building energy supply-demand due to the diversity and uncertainty of user load demand. By combining various types of energy storage equipment, hybrid energy storage technology was created, which allows for the coordination and complementation of multiple energy sources. This paper first introduces the principle of hybrid energy storage technology in building energy application, then summarizes the research process of hybrid energy storage technology from the perspective of building energy demand, and finally identifies the main research direction of hybrid energy storage at this stage. Secondly, based on several common matching methods of hybrid energy storage, this paper summarizes the application status of hybrid energy storage technology of heat energy, gas chemical energy, and electric energy and introduces the system composition, operation strategy, and system characteristics of corresponding hybrid energy storage according to typical cases, and explains how to meet the multi-energy demand of building users. Finally, the performance and economy of the hybrid energy storage system are examined, and important indexes for evaluating the hybrid energy storage system's performance and the main factors influencing its economy are proposed.

Key words: hybrid energy storage, building energy system, matching method, performance, economy
