A frequency modulation control strategy for VSG systems with additional active power constraints is proposed by overlaying the active power changes of photovoltaic and energy storage systems through appropriate functional relationships into the control loop of synchronous generators.
The result of this project can also be extended and applied to the primary frequency control of grid-connected photovoltaic power stations in the power grid, and even further applied to the joint frequency modulation optimization control of the multi-energy complementary interconnected power system of the power grid.
This paper proposes a frequency modulation control strategy with additional active power constraints for the PV-energy storage-diesel micro-grid system in the renewable energy power system, using the PV-energy storage-diesel VSG four terminal micro-grid system model combined with actual operating conditions.

(kj2022-058) (Research on control strategy for improving the frequency response characteristics of photovoltaic and energy storage systems based on VSG control).
After k transformation, the frequency modulation generator adaptively increases or decreases the power and adjusts the system frequency according to the system power change rate, thereby improving the system's support ability for the power grid (Guofeng et al., 2022, Zhang et al., 2023b, Ke et al., 2020, Rasool et al., 2020).
The frequency modulation of thermal power unit has disadvantages such as long response time and slow climbing speed. Battery energy storage has gradually become a research hotspot in power system frequency modulation due to its quick response and flexible regulation.
