Abstract in different language:	The future planned development of decentralized electricity generation may have a negative impact on the operation and management of the electricity system. Above all, problems can be expected with maintaining voltage and frequency stability in island microgrids, where the only sources of electricity will be photovoltaic power plants. With the growing consumption of electricity and the growing demand for the quality of the supplied electricity, there is a need to regulate these renewable energy sources more appropriately. One of the possibilities could be the primary and secondary regulation of voltage and frequency using the so-called virtual frequency and voltage method. The main aim of this paper is to analyze and compare the current regulators of the voltage inverters of the photovoltaic power plants with the proposed inverter regulator enabling primary and secondary regulation. The functionality of the solved control circuits of inverters is assessed on the basis of the results of the simulations of the small island microgrid with a symmetrical and asymmetrical load in the MATLAB Simulink software.
