Modeling of Electrical Power System with Distributed Generation Source

Analysis and modeling of an electrical power system with a distributed generation source in normal mode were carried out using the Matlab application program. The paper provides an analysis of the state of the electric power system, the main parameters of which change when an additional source of distributed generation based on a wind farm with a capacity of 9 MVA is introduced. A block diagram and, based on it, a simulation model of the power system have been compiled. Since the stability of the electric power system depends on the reliable operation of the emergency automatics, it is necessary to determine the values of the main parameters of the electric power system that characterize its stable operation: the change in the phase shift angle between the emf of the generator and the network voltage and the change in the main electrical quantities at the consumer source terminals.
