Abstract
In grid-connected applications, the photovoltaic (PV)-based power generation is getting more attention these days due to several factors like pollution-free, single investment plant, etc. However, it has the drawback of interruption in power generation, which makes it undesirable to power system. In order to overcome this drawback, a constant power is supplied to the grid by integrating energy storage system like battery and/or ultra-capacitor with solar PV. This paper proposes a grid-connected PV-battery-based hybrid power system to deliver a constant power to the grid. Modeling and simulation of solar PV-battery-based hybrid system have been developed and the constant power management controller (CPMC) is ensured to inject constant power at the change in environmental conditions. The simulation result shows the performance of proposed control algorithm to PV-battery-based hybrid system is validated.
