With the centralized access of large capacity and high proportion of new energy to the power grid, the power structure has undergone great changes, and the fast frequency response resources available to the power grid have gradually decreased. If high-power DC blocking occurs, it will pose a serious threat to the frequency security of the power grid, and the frequency regulation pressure of the power grid and the risk of safe operation will continue to increase. To this end, a fast frequency response technology for photovoltaic power plants based on equivalent modelling is proposed. According to the principle of equivalent modelling, the equivalent model of a single unit of photovoltaic power station is established through the parameters of photovoltaic array, photovoltaic inverter, unit transformer, unit transformer and collector line. According to the fast frequency response performance requirements of photovoltaic power plants, combined with the characteristics of photovoltaic power plants, a feasible scheme for fast frequency response of photovoltaic power plants is introduced. The case study on the implementation of fast frequency response project in photovoltaic power station shows that according to the order and type of AGC command and fast frequency response command, photovoltaic power station has conducted command superposition tests under 50 ±0.2 Hz and 50 ±0.09 Hz disturbance amplitudes respectively, and the results are qualified. The integration of automatic generation control/automatic voltage control (AGC/AVC) and fast frequency response function of photovoltaic power station is realized by using relevant technologies, so that the photovoltaic power station can actively support the grid frequency and voltage.

This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.

“…The Power Synchronization Control (PSC) concept was applied, and an inertia emulator was implemented. On the other hand, regarding the application of statism curves (droop control) in the control of power systems, different methods have also been suggested in the literature for controlling voltage and frequency [13][14][15][16][17][18][19][20][21][22][23].…”

An Active/Reactive Power Control Strategy for Renewable Generation Systems

The development of distributed generation, mainly based on renewable energies, requires the design of control strategies to allow the regulation of electrical variables, such as power, voltage (V), and frequency (f), and the coordination of multiple generation units in microgrids or islanded systems. This paper presents a strategy to control the active and reactive power flow in the Point of Common Connection (PCC) of a renewable generation system operating in islanded mode. Voltage Source Converters (VSCs) are connected between individual generation units and the PCC to control the voltage and frequency. The voltage and frequency reference values are obtained from the P–V and Q–f droop characteristics curves, where P and Q are the active and reactive power supplied to the load, respectively. Proportional–Integral (PI) controllers process the voltage and frequency errors and set the reference currents (in the dq frame) to be imposed by each VSC. Simulation results considering high-power solar and wind generation systems are presented to validate the proposed control strategy.
