ABSTRACT
Distributed generation can allow utilities to defer transmission and distribution upgrades. With the right configuration, distributed generation can also improve customer reliability and power quality. Applying generation closer to the load benefits the transmission and distribution infrastructure. Many distributed generation technologies can supply isolated loads in stand-alone applications, but also having a utility supply adds considerable value. The presence of the utility distribution system solves many of the problems with customer-owned generation systems: reliability; matching load; and load following and source stiffness. Distributed generation technologies continue to advance: cost comes down and performance improves. The chapter focuses on the application of generators on radial distribution systems. The application of generators on spot or grid networks requires special considerations because of the use of network protectors that operate on reverse power flow. Three power converters convert the power output of the energy source into interface with standard 50- or 60-Hz systems: synchronous generator; induction generator; and inverter.
