Abstract

Solar Photovoltaic (PV) technology is one of the renewable energy source technologies to realize the shift to decarbonize energy supply because of availability of safe, limitless, free and reliable long-term sources of power. PV modules/cells are instruments to convert this solar energy to DC energy. Grid interconnection with solar power system is comparatively easier to install as the same do not require storage system. This paper presents injection of 3 kW power generated from solar PV array to 230V grid distribution network. Technique uses phase angle difference between grid voltage and voltage source inverter. The grid acts like a virtual energy storage system with an unlimited storage capacity. Hence, the proposed system is designed without a battery backup. This system is simulated in MATLAB/Simulink to confirm the desire output. In the second step, hardware circuit is designed and implemented based on the simulation results.
