The dissertation thesis deals with the design of the concept and implementation of models of electrical power system elements with regard to the potential of the use of computer programs – simulations. The solution of the thesis focuses on the compliance simulations of power-generating modules according to RfG (Requirements for Generators), as a document which setting out the requirements for the connection of power-generating facilities and also focuses on the issue of smart grids and MAS (Multi-Agent Systems) respectively. The framework of the thesis is thus defined by the area of requirements for power-generating modules according to legislative requirements (not only RfG, but also related standards incl. DSC (Distribution System Code), CSN EN 50438 and CSN EN 50549), requirements for agent functionalities and power-generating module abilities to operate in synchronous and island operation, including transitions between them, the process of synchronization (phasing) and communication between the individual elements of the power system.
