Compared to primary regulation, secondary frequency regulation offers higher control accuracy but a slower response time, as it involves communication, decision-making, and execution processes. At the same time, with the rapid development of renewable energy and the increasing demand for flexibility in power systems, electrochemical energy storage technology has shown great. . The methods for controlling the frequency of the power grid include primary frequency regulation, secondary frequency regulation, high-frequency switching, automatic low-frequency load shedding, unit low-frequency self starting, load control, and DC modulation. Each serves a unique purpose and works at different timescales, but both are vital to grid stability—especially with the increasing penetration of renewable energy.

Figure 1 shows the approximate role of different operating reserve products in response to a system contingency that leads to a decline in frequency. . Primary frequency response (PFR) is one of the important reserve services used by grid operators to uphold steady frequency. Modeling PFR has historically been rare in grid integration and planning studies, but it could become more important with greater deployment of nonsynchronous generators. A reduced second-order model is developed based on aggregation theory to simplify the multi-machine system and facilitate time-domain frequency. . Since grid support with energy storage devices is becoming more attractive, the aim of this paper is to analyse the viability of providing primary frequency regulation with. It also allows batteries with a low state of charge to participate in frequency regulation without risking battery degradation or regulation failure. This strategy integrates virtual inertia. .
