Power Generation Side Energy Storage Application
THERMAL POWER PLANT FREQUENCY MODULATION APPLICATION
Solution Features:
- Improve the frequency modulation capability of thermal power plants and effectively provide grid frequency stability
- Increase power plant revenue
- Large multiple charge and discharge of energy storage batteries
MULTI-ENERGY COMPLEMENTARY ENERGY STORAGE SOLUTION
Among renewable energy, wind energy, hydropower and solar energy are the fastest developing and most promising renewable energy sources, each with its own char- acteristics, and complementary in time and space. Their complementary power generation is more efficient and reliable than single power generation. It can smooth electricity generation and use, make up for the instability defects of new energy power generation, and avoid waste.
Various new energy power generation areas and powerless or weak power areas
Solution Features:
- Multi-energy complementarity, balanced power supply
- Improve the stability and economy of grid power generation
- Improve the dispatch ability of the grid
ABANDONED WIND AND ABANDONED LIGHT/PLANNED POWER GENERATION SOLUTIONS
Due to the intermittent, fluctuating and unpredictable characteristics of new energy power generation, large-scale access will inevitably increase grid regulation diffi- culties and may cause a large amount of abandoned light and abandoned wind prob- lems. Adding an energy storage system on the new energy power generation side can solve these problems well. The unused electricity is stored and released during power shortage or peak power consumption to smooth power generation and con- sumption, make up for the instability defects of new energy power generation, and avoid waste.
Solution Features:
- Reduce abandoned light and abandoned wind and improve economic efficiency
- Improve grid-connected power generation stability and predictability
- Suitable for medium and large system applications
- Renewable energy power limited areas, etc.
DC Bus Solution
- No need for grid access points, suitable for new systems
- Save initial investment costs
- Suitable for small and medium system applications
SMOOTH POWER GENERATION OUTPUT APPLICATION
The output of new energy sources such as photovoltaics and wind power has strong fluctuations. Large-scale grid connection will cause many adverse effects on the economic and safe operation of the grid. This also limits the scale of new energy power grid connection and restricts the largescale development and utilization of new energy power generation. Energy storage can effectively suppress the output curve of new energy power generation. It is of great significance to improve the operation performance of large-scale new energy power grid connection.
