Harmonic Analysis of 1.5 kW Photovoltaic System in the Utility Grid

[摘要] The photovoltaic systems are safe and clean source of energy, so the use of photovoltaic systems has been rapidly increasing nowadays. The harmonic has to be analyzing for 1.5kW photovoltaic system in the utility grid at the point of common coupling. The grid-connected photovoltaic system is used to provide energy for local loads and for exchanging the power with utility grids. At the point of common coupling, this power quality problem arises mainly due to the connection of non-linear loads and this issue has to be suppressed. This paper assesses the impact of PV generation on the distribution system and important issues such as reverse power flow and harmonic distortion are analyzed.
