What is the optimal grid-connected strategy for energy storage power stations?

In this section, energy storage power stations are considered and the optimal grid-connected strategy based on load fluctuation is adopted. The maximum charge and discharge power of energy storage power stations is 150 MW. The operating results of the energy storage power station are shown in Fig. 7.

Will storage devices become increasingly widespread for grid systems?

The present trajectory indicates that storage devices will become increasingly widespread for grid systems as RE becomes a more significant part of the energy supply mix , . The infrastructure of the power system makes use of ESSs at numerous stages.

Why do we need a power grid?

Power grids are the foundation of energy systems, playing a key role in the energy transition by enabling the use of renewable energy sources (RES). To meet the growing demand for renewable energy, the world may need to integrate RES into power grids—but there are hurdles to overcome.

Why do we need a grid-connected energy system?

Such a grid-connected strategy not only makes the load fluctuation after grid-connected as stable as possible but also optimizes the operation income of new energy sites. Due to the completion of “Peak shaving and valley filling”, also reduces the output of high-pollution and high-cost units to a certain extent.

What is the optimal grid-connected strategy?

Furthermore, under the optimal grid-connected strategy based on the operation income of new energy stations, the revenue of these plants increased by 22.40% compared to direct grid connections of wind power and photovoltaic systems.

Can energy storage systems sustain the quality and reliability of power systems?

Abstract: High penetration of renewable energy resources in the power system results in various new challenges for power system operators. One of the promising solutions to sustain the quality and reliability of the power system is the integration of energy storage systems (ESSs).
