POWER GENERATION SIDE ENERGY STORAGE APPLICATION

THERMAL POWER PLANT FREQUENCY MODULATION APPLICATION

With the grid connection of new energy, the fluctuation and randomness of wind and solar energy causes energy imbalance in the grid in a short time. Traditional energy has lag in response to signals due to slow frequency modulation speed, so it cannot meet the new demand. Energy storage has a fast frequency modulation speed and adjustable capacity, so it becomes a very good frequency modulation resource.After the thermal power plant adds an energy storage system, it can effectively improve the Kp value in actual application and increase the revenue of the power plant.
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 characteristics, 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.

Applicable scenarios
  • 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 dispatchability 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 difficulties and may cause a large amount of abandoned light and abandoned wind problems. 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 consumption, 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

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.
