There are a variety of techniques available for harmonic removal techniques. The methods have their own performance
with respect to application. Also, cost of implementation of particular harmonic removal technique depends on the discrete
and semiconductor components used while developing filters. Due to higher demands of electricity, power generations with
low cost are most essential needs of the world. Photovoltaic-based power plant implementations are cost effective for longterm
power generations due to technological advancements. While generating power from PV solar cells due to variations
in the solar radiations, harmonic effect is seen. The harmonic reduction is the most important need while establishing gridconnected
PV solar power plants. This paper introduces the review of various techniques for removing harmonics in PV
solar power plant developed by various researchers. The addressed techniques are studied based on their robustness,
implementation complexities and performance characteristics.
