Selected aspects of photovoltaic power station operation in the power system

This paper presents the results of a five-year study of a 1 MW photovoltaic power station in the Warmia and Mazury Province. The research involved measurements of active energy, currents, voltages, active, reactive and apparent power and higher harmonics of currents and voltages. The operation of this plant was analysed in terms of electricity produced and active power generated to the power grid in individual years, months and days. The analysis concerning the impact of the plant on the power grid in terms of the quality of electricity supplied included the results of three-day measurements of not only active, reactive and apparent power, but also of higher harmonics of currents generated to power grids on the low-voltage side, the results of which were recorded every second.
