Main features of analysis of disturbances impact from diverse types of DG sources on the loads

The electric power is most universal and widely used form of energy, which world demand grows constantly. Electric power supply system is one of the most effective components of the infrastructure on which modern society depends. To meet the growing demand for electricity and the need to reduce carbon emissions, the new model of the electric power system, which must have the features of sustainable development to be reliable, and its architecture and operating conditions economically justified should be developed. Modern power system must undergo significant- changes. The paper deals with the integration of distributed generation sources in the Smart Grid-systems, improving energy efficiency and reduce emissions in the energy, power generation and dispersed all kinds of noise inherent in a particular type of sources. By using the MatLab software all options considered electrical circuits were modeled and waveform and THD performance for all sources of electricity were obtained.
