 The paper analyzes the stability of electric power system with distributed generation by simulation modeling in an environment of Matlab. The voltage at the node points is taken as parameters of stability of power supply systems. Difficulties of operation of emergency control systems in comparison with centralized power supply system have been determined. The basic principles of ensuring the stability of electric power system with distributed generation for consumers of electricity, the load of which does not change over time, which include enterprises of the mining industry, steel furnaces and coal mines, are outlined. A description of the power supply system for an industrial area is given. The results of modeling the power supply system in the Matlab environment are presented. The model presents the main equipment of the power supply system of the region, a set of control and measuring instruments for monitoring changes in electric and mechanical parameters on the main generator’s clamp. The main parameter, characterizing stability of power supply system, change of phase angle between EMF of generator and mains voltage is revealed. The time of transient process at start of the main generator, time of the end of transient process and difference of angles between EMF of generator and mains voltage were determined on the basis of the diagram.
