About Solar power generation voltage limit
Active power curtailment aims to prevent the occurrence of voltage fluctuations by limiting the active power output of a solar PV system through the inverter. The goal of curtailment is to smoothen the PV power output profile by limiting sudden power changes ( d P in Eq.

Results of the proposed control strategy under high power generation scenario at G = 1000 W/m 2 (a) grid voltage, (b) injected active power, (c) injected reactive power and (d) inverter.
The paper investigates the issue of high PV penetration effects with respect to the total installed power generation capacity of PV power plants in the MG and presents a coordinating voltage control solution to maintain the voltage limits of V min = 0.95 and V max = 1.05, which were chosen according to the ANSI standard.
The following four modes utilize reactive power to help manage voltage: • CONSTANT POWER FACTOR MODE: Generation operates with a fixed power factor (typically 0.95 – 0.98 leading PF) such that reactive power is proportional to active power generated. Unity PF is the default setting in 1547-2018. • VOLTAGE-REACTIVE POWER (VOLT-VAR) MODE:.
