VOLTAGE AND FREQUENCY CONTROL FOR ISLANDED MICROGRIDS CONTAINING PHOTOVOLTAIC POWER PLANTS

Lenka Raková – Emil Dvorský

   The article deals with the strategy of primary and secondary control for photovoltaic power plants in islanded microgrids. The first part describes the regulation possibilities of photovoltaic power plants and a characteristic of the virtual active and reactive power method. The following and final parts present the simulation model and results of primary and secondary control created in the MATLAB Simulink software environment. Inter alia, the aim of this article is also to assess the effect of load place on accurate power share achieving between two distributed generators.

Keywords: primary control, secondary control, microgrids, photovoltaic power plant, virtual powers method
