Opis:: The numerical modelling of the photovoltaic module and the solar inverter interconnected with the microgrid has been carried out with the use of PowerSys in Matlab/Simulink. Algorithms of P, Q controllers have been proposed. The capability of the active and reactive power reference tracking has been tested for various conditions.

Opis:: This papers discusses the analytical analysis of the syochrophasor estimation employed in electrical systems. Short time Fourier trsnsform with the phase locked loop and Taylor Fourier series are analyzed for signals relating to different states which may occor in real power systems. The object is the accurate phasor estimation regardless of the shape of input signal, what for some signal types is cumbersome. As a result of active and reactive power disturbance in a power system, the frequency deviation and amplitude fluctuations may appear in power system signals. As a consequences of short circuits or overvoltages signal changes occur. Ibis leads to unacceptable errors in short time Fourier transform resulting from Fourier transform properties. This paper presents character of occurring errors and their consequences individually for any signal deviation.
