9MWh Frequency Regulation Energy Storage System Feasibility Study

This feasibility study report, prepared by XX Design Co., Ltd. for Hubei XXXXXX Co., Ltd., evaluates the implementation of a 9MWh frequency regulation energy storage system. The document covers project background, market status, and technical design. It analyzes the domestic frequency regulation market, current Hubei power system conditions, and relevant policies. The electrical design includes primary and secondary systems, black start methods, and relay protection. The energy storage system design details battery selection, inverter specifications, step-up transformers, and protection functions. Civil engineering aspects cover site planning, roads, vertical layout, and structural design, including geology, hydrogeology, and earthquake considerations. Fire protection and video surveillance are also addressed. The study aims to enhance grid stability and support renewable energy integration through advanced energy storage technology.
