Wind-solar-storage transformer solutions
The CEEG energy storage industry solution focuses on energy storage scenarios, effectively improving the stability of power output and helping energy storage customers enjoy more economical, greener, and more efficient energy.
Highly integrated, highly adaptable power system solutions for renewable energy and energy storage scenarios
Renewable power generation is characterized by volatility, intermittency, and strict grid-connection requirements, and energy storage systems must play a key role in grid peak shaving, power smoothing, reactive power compensation, and adaptation to complex environments. For wind-solar-storage scenarios, CEEG provides integrated energy storage step-up converter units, dedicated energy storage transformers, and system integration solutions.
The solution supports standalone energy storage, wind-solar-storage integration, microgrids, and other application scenarios, covering engineering consulting, design, system integration, and station-level monitoring to help customers achieve fast installation, stable operation, and integrated delivery.
New energy power system challenges
Grid-Side Challenges
High volatility of renewable generation affects grid stability
Growing peak-shaving pressure on the grid demands greater regulation capability
Growing demand for source-grid-load-storage coordination
Strict grid-connection standards for distributed power sources
Equipment-Side Challenges
Harsh operating environments (high temperature, high humidity, salt spray, etc.)
Complex load characteristics (intermittent and random)
Severe harmonic pollution that shortens equipment service life
Difficult maintenance, high reliability requirements
