FAQS 4

Does energy storage integration improve power system inertia?

In summary, most existing literature focuses on the evaluation of inertia demand or the improvement of system inertia after wind turbine participation in frequency regulation, but no quantitative research has been conducted on the improvement of power system inertia level after energy storage integration.

What is generator inertia?

Generator inertia is our starting point for examining how fast the system must respond to a contingency event. This section details how generator inertia resists changes in system frequency. Under normal conditions, electricity demand is met by the constant injection of energy into the grid from many power plants.

What is inertia in power systems?

Inertia is an intrinsic property of power systems that stabilizes the grid frequency and introduces a relationship between frequency and the balance of power supply and demand. Previously, synchronous generators and induction motors were directly connected to the power grid and were the main source of inertia (Shi et al., 2019, Lin et al., 2022).

Are energy storage systems suitable for inertia provision?

Although a wide array of energy storage systems has emerged in recent years to fulfill different grid services, not all are suitable for inertia provision (Farhadi and Mohammed, 2015). Among these options, high-power storage systems can best emulate inertia in power grids (Alsaidan et al., 2017).
