Abstract

As the economic growth and population increase, the demand for energy supply has also increased. The disadvantages that power generation based on non-renewable energy sources bring to the environment has stimulate the idea of generating clean and sustainable power in a huge amount from renewable energy sources like solar and wind energies. In recent years, photovoltaic (PV) systems are mostly used due to its light and easy-installable characteristics. It has two approaches which are stand-alone PV system and grid-connected PV system (GCPV). Although it is said to be the most promising renewable energy, it could not avoid disturbance. In GCPV, faults could occur on the grid side, leading to overshoot voltage in DC-link and overshoot grid current. These situations could stress electrical components and decrease power quality of the system. Therefore, many protection schemes have been introduced to overcome this matter. A brief discussion on the growth of GCPV technology together with the impacts of grid faults on it were presented in this paper. Then, several conventional protection schemes implemented in GCPV were also reviewed. In the end, a new protection scheme namely zero state protection scheme that has the same function to limit the overshoot DC-link voltage was proposed.
