Fault Current Issues for Market Driven Power Systems with Distributed Generation

-This paper presents the consequences and operating limitations of installing distributed generation (DG) to electric power systems. The proliferation of new generators creates new operating conditions, some not seen before, that are limited by fault interruption capability. Increased system fault currents resulting from DG installation and the effects of increased fault currents are discussed. A technique used to evaluate fault current in the system after installing DGs is analyzed, and an example is given. The responsibility for the system change and safety degradation is discussed.
