When PV power stations face curtailment at noon, when wind farms experience output fluctuations late at night, when factories lose millions in profit due to peak-valley electricity pricing—CEEG's PCS Turnkey Station with MV Transformer Integrated is simultaneously fighting energy efficiency revolution battles across three frontiers, giving rise to energy powerhouses exported to 40 countries.
True zero-carbon transformation begins with ultimate control over every kilowatt-hour. CEEG's PCS Turnkey Station with MV Transformer Integrated features high-voltage side voltage coverage from 6kV to 35kV, transformer low-voltage side AC voltage ranging from 0.315kV to 0.69kV, and transformers encompassing various models of dry-type and oil-immersed types. Energy efficiency levels are executed according to design requirements and can be flexibly customized.
Commercial & Industrial Energy Storage: Precision Calculator for Electricity Price Arbitrage
Inside an electronics industrial park, CEEG's PCS Turnkey Station serves as an "intelligent power steward": during daytime when PV generation is at full capacity, surplus power is stored in battery arrays; the moment evening peak electricity prices surge, the station precisely releases stored power.
When the grid experiences sudden fluctuations, the 0.315kV low-voltage side monitors production line load variations in real-time, dynamically switching charge-discharge strategies through intelligent EMS. The isolation transformer built into this steel nerve center instantly establishes safety barriers, ensuring zero downtime for precision instruments, extending equipment lifespan, and significantly compressing investment payback periods.
PV Power Stations: The Curtailment Breakthrough Solution
Facing the 12% average daily curtailment rate at Northwestern China's PV bases, CEEG delivers a disruptive solution empowered by three-fold adaptive technologies: next-day generation curve forecasting, intelligent charge-discharge depth regulation, and high-precision temperature control system management.
The PCS Turnkey Station's DC side directly connects to PV arrays, with the 1500VDC high-voltage channel functioning as an energy expressway, efficiently directing otherwise wasted solar power into the energy storage system. When grid electricity prices climb in the evening, the stored energy is boosted to 35kV through the turnkey station and injected into the grid.
Wind Farms: The Power Fluctuation Tamer
At the Bohai Bay wind farm, the PCS Turnkey Station is performing an even more sophisticated balancing act. When gusts cause power surges of 10MW, the equipment activates ultra-charge mode to prevent grid impact; during calm periods, stored energy continuously outputs to ensure grid agreement compliance.
CEEG's PCS Turnkey Station provides buffering for wind power grid integration, smoothing output fluctuations and enabling energy dispatch. It can dynamically and rapidly absorb energy and release it at appropriate times, improving power quality, enhancing wind power controllability, and elevating power system stability.
