The Largest Independent Energy Storage Power
It is the largest grid-side independent energy storage power station for frequency regulation and peak shaving in the Guangdong
To leverage the efficacy of different types of energy storage in improving the frequency of the power grid in the frequency regulation of the power system, we scrutinized the capacity allocation of hybrid energy storage power stations when participating in the frequency regulation of the power grid.
With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
A droop control strategy for energy storage batteries to participate in grid frequency regulation has also been raised. By adjusting the output of the energy storage battery according to the fixed sagging coefficient, the power can be quickly adjusted and has a better frequency modulation effect.
