Can a grid-connected PV inverter control overvoltage and undervoltage? Generally,a grid-connected PV inverter can be programmed to inject and absorb the reactive power.
Photovoltaic (PV) inverters are vital components for future smart grids. Although the popularity of PV-generator installations is high, their effective performance remains low. Certain inverters are designed to operate in volt-ampere reactive (VAR) mode during the night.
Generally, a grid-connected PV inverter can be programmed to inject and absorb the reactive power. Hence, both the overvoltage and undervoltage conditions can be regulated using the reactive power control ability. The dq components theory, which will be described in Section 2, can be used to perform the controlling mechanism efficiently .
For photovoltaic (PV) inverters, solar energy must be there to generate active power. Otherwise, the inverter will remain idle during the night. The idle behaviour reduces the efficiency of the PV inverter. However, if there is a mechanism to use such inverters in a different way at night, its efficiency can be increased.
The PV inverters theoretically can be developed as reactive power supporters, the same as the static compensators (STATCOMs) that the industrial standards do not address . Typical PV inverters are designed to be disconnected at night. Alternatively, it is possible to use its reactive power capability when there is no active power generation.
Using the inverter as a reactive power generator by operating it as a volt-ampere reactive (VAR) compensator is a potential way of solving the above issue of voltage sag . The rapid increase in using PV inverters can be used to regulate the grid voltage and it will reduce the extra cost of installing capacitor banks.
In the event of a power outage, the inverter automatically switches to backup power operation and the entire household is supplied with energy via the photovoltaic system and the battery. This means it is possible to supply both single-phase and three-phase loads, such as an electric oven or a heat pump. A battery storage system is needed for this.
