200MW/800MWh Shared Energy Storage Project Feasibility Study

This feasibility study report, dated February 2024, examines a 200MW/800MWh shared energy storage project. It begins with an overview of the project background, investors, and research scope, establishing the necessity of construction. The report then analyzes the regional power system, including current geographical wiring, system status, and the need for the project, proposing an access system solution with requirements for electrical equipment parameters, relay protection, scheduling automation, and communication. Site conditions are evaluated, covering overview, transportation, and comparisons leading to recommendations. The overall plant and station area planning are detailed, including master and vertical plans. Two energy storage technologies are explored: all-vanadium redox flow batteries, with selection, introduction, wiring principles, and electrical parts; and compressed air energy storage, covering installation plans, technical route comparisons, system design, operation modes, auxiliary facilities, waste heat recovery, workshop layout, and innovation plans. The report also addresses site-wide public systems (building structure, HVAC, water supply, fire protection, lighting), environmental protection and soil conservation, and labor safety and industrial hygiene, concluding with comprehensive findings and suggestions.
