Industrial Application of MicroGrids

The following report summarizes the benefits of introducing Distributed Resources within an industrial site. To have a realistic example for this work it was necessary to design the site. The plant is assumed to be one that manufactures either paper or plastic film using a continuous process. This requires extensive induction machines that need to be tightly controlled to insure correct tension of the film during the process. The site has three main buildings: the factory with 50,000 ft² of floor space, the warehouse and the office with 57,000 ft² and 18,000 ft² of space respectfully. This site has an overall demand of 1MW and is connected to the main grid through a series of transformers, overhead lines and cables. There is also another load in the immediate vicinity of the one under study which allows a platform for disturbances do to load changes and faults. The feeders from the 120KV source to the 120 volt service deep within the plant was designed using standard engineering practices.
