Implementation of Photo-Voltaic Inverter for Voltage Stability in Grid-Connected System Using PI Controller

There are changes administrated in the power grid, which is being ushered by the entry of more megawatt-scale photovoltaic (PV) power plants and other massive inverter-based power stations to the power grid. In addition to these alterations, new grid code specifications denote that inverter-based power plants not only maintain timeline set in the event of failure but also offer dynamic support. This proposed method has been used with Proportional-Integral (PI) control and also improves voltage stability by injecting reactive power. Information from simulations diagram and results are presented to show that how proposed control scheme works effectively.
