This control strategy involves adjusting the active power output of the PV inverters based on the local voltage levels. When the voltage at the PCC exceeds a certain threshold, the PV inverter reduces its power output to prevent further voltage rise and maintain the voltage within acceptable limits.
The increase in bus voltage is used as the control signal of the PV output current to reduce the photovoltaic output current, such that the PV output power is reduced from 3000 W to the inverter power limit value of 1500 W, which meets the requirements of the inverter output power limit.
Gadget number two, a PV inverter, may also be a viable option . Reactive power is required to increase the electrical grid’s capacity. Consequently, a PV inverter providing reactive power is necessary. A PV power system that is currently in use needs a dependable power source to function .
Based on the previous control of the inverter’s output unit power factor, a reactive power compensation control strategy for single-phase solar power inverters is proposed. Use instantaneous no-power theory to realize the effective power control and reactive power compensation of the inverter, and optimize the function of the inverter.
By optimizing the reactive power (Volt/VAr) control of smart inverters for photovoltaic (PV) systems, the method not only prevents voltage violations but also ensures that the necessary curtailment of power is fairly distributed among all PV inverters.
However, challenges related to power quality, stability, and power output mismatches arise when PV systems are connected to the grid via inverters. Inverters, being pivotal power electronic converters, convert the DC from RES to AC, enabling the supply of electricity to AC loads or the utility grid 5.
