Conclusion This paper proposes a fuzzy-based control strategy for the grid-connected solar photovoltaic system to participate in primary frequency regulation without any energy storage support. A combined fuzzy based de-load control and control mode selector was proposed to enable PV operation at a scheduled level of power reserve.
This article proposes a frequency droop-based control in DPV inverters to improve frequency response in power grids with high penetration of renewable energy resources. A predefined power reserve is kept in the DPV inverter, using flexible power point tracking. The proposed algorithm uses this available power reserve to support the grid frequency.
During the participation of photovoltaics in grid frequency regulation, different frequency regulation tasks are required at different time scales. The grid demands that photovoltaics (PVs) improve steady-state frequency when facing short-term load fluctuations, while also enhancing frequency response to long-term environmental and load changes.
This strategy allows PV power generation systems with different reserve capacities to participate in frequency regulation, optimizing the load reduction controller and ensuring system frequency stability. However, this strategy cannot fully utilize the frequency modulation potential of photovoltaics with different capacities.
When the inverter operates at lower power, the switching loss of the power device is no longer a limiting factor. Therefore, increasing the switching frequency of the power device according to certain constraints as the output power is reduced helps to reduce the harmonic content of the grid current and improve the grid-connected power quality.
From the perspective of control strategies, the participation of PV systems in primary frequency regulation can generally be categorized into two types: load reduction control and coordinated control with PV-energy storage systems.
