Abstract
Much of the new generation capacity installed during the next 10 years will be accomplished through the construction of IPP (Independent Power Producer) generating facilities. These facilities can take the form of small distributed generating (DG) units, or large capacity plants owned and even operated by non-utility personnel. It is forecasted that many of the distributed generating units will be at smaller industrial and commercial facilities and operating in parallel with the utility system to reduce energy cost through load sharing or "peak shaving." This paper discusses the protection requirements to interconnect these generators to utility systems, as well as methods to reconnect these generators after interconnect protection tripping.
