In the proposed method, PVs are mainly controlled to ensure the level of comfort for EV owners. The modified three-phase damping control strategy has been proposed to mitigate overvoltage and voltage unbalance in low-voltage distribution networks by controlling the active and reactive power of three-phase inverters .
This paper proposes a coordinated voltage control by three-phase step voltage regulators (3 ϕ SVRs) and photovoltaic (PV) units with smart inverters. An optimization problem is formulated to improve the voltage profile of distribution networks and reduce the active power curtailment of PVs.
Modern electronic systems cannot function without three-phase inverters, which transform DC power into three-phase AC power with adjustable amplitude, frequency, and phase difference. They are essential in several applications, including as power distribution networks, renewable energy systems, and industrial motor drives.
The unexpected potential of the open terminal is determined by the load characteristics. The 120-degree conduction mode of each transistor results in underutilization when compared to the 180-degree conduction mode for the identical load state. Due to these reasons, three-phase inverters prefer to operate in the 180-degree conduction mode.
