Effect of distributed generation to the faults in medium voltage network using atp-emtp simulation

Abstract

During past few years, distributed generation (DG) technology has been widely known in the industry as it can helps in providing backup power during high power demand. However, adding a new system may changes the traditional power system that are usually work in one direction which is from the generation to the consumer. When DG is added, the power flows from two direction. Therefore, a short circuit study was done to study the effects of DG to the local system during fault. An IEC Standard was also calculated as guidance to determine the thermally permissible of a cable.
