Summary:

Problems of power quality and electric energy accounting often occur in networks with large pervasion of photovoltaic (PV) elements on rooftops of household and office buildings. In smart grids, including PV arrays electricity, which is sold back to the distribution network, requires approval of its parameters and quality control. Distributed power inverters generate higher harmonics which affect relay protection, automation systems, smart meters and power system’s reliability. In this article the influence of photovoltaic elements on the accuracy of electric energy metering and power quality questions are analysed.

Keywords: smart meter, harmonics, power quality, pulse-width-modulated inverter, smart grid
