Assuming that the bid FR power of each ES unit is its rated power in the regional power grid.
The traditional approach to frequency control in power grids involves approximating the system as a linear model based on a specific operating condition without taking into account the dynamics of the generators.
However, this study considered numerous load perturbation profiles like, step load disruptions (SLD) (,) series SLD, and random load disruptions (RLD) which represent the forced outage of power plants or high change on the load demand.
As impetus to society from fossil fuel to low-carbon energy era, energy storage with swiftness and accuracy applies itself in frequency regulation in power system under the issue on frequency.
According to the above analysis, the energy storage technology can effectively improve the frequency regulation performance by assisting thermal power units to participate in power grid frequency regulation, and the control strategy proposed in this paper can prolong the service life of the energy storage system.

This article explores mainstream storage technologies like molten salt systems, phase-change materials, and thermochemical storage while analyzing. To eliminate its intermittence feature, thermal energy storage is vital for efficient and stable operation of solar energy utilization systems. It is an effective way of decoupling the energy demand and generation, while plays an important role on smoothing their fluctuations. In a concentrating solar power (CSP) system, the sun's rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use.
