The company's wind power operation and maintenance project department in Yucheng, Dezhou, Shandong province consists of seven 6.25MW wind turbine units and one 4.25MW wind turbine unit, with a total installed capacity of 48MW and a synchronous 16.8MW/33.6MWh energy storage facility.
The project department is currently conducting grid-connected testing for energy storage systems. To implement the company's cost optimization strategy and minimize electricity losses for clients, maintenance personnel coordinated with project owners, manufacturers, and testing agencies. The testing schedule was implemented starting at 1:00 AM for charging operations and 6:00 PM for discharging operations. This dual approach ensures the use of off-peak electricity during charging to reduce grid-connected costs, while simultaneously replenishing power supply during evening peak hours. This strategy effectively addresses potential grid shortages caused by high user demand exceeding renewable energy output, thereby maintaining stable and secure grid operations.
