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.

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).

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.

Why is grid-connected power system important?

This indicates that the optimal grid-connected strategy not only stabilizes the load fluctuations caused by wind and photovoltaic power connection but also improves the economic and environmental performance of the power system.

What is the objective function of a grid-connected energy system?

The objective function remains to minimize the generalized load fluctuation coefficient after the connection of wind and photovoltaic power. 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.

Why is energy storage important in power grid demand peaking and valley filling?

The simulation test also reveals the important role of energy storage unit in power grid demand peaking and valley filling, which has an important impact on balancing the instability of photovoltaic power generation and improving the system response ability. 1. Introduction
