Integration of Renewable Energy Resources in the Distribution Network of Industrial Enterprises

Distributed generation is understood to mean the totality of sources of electrical energy closest to consumers. Traditionally, the flow of electric energy is unidirectional and comes from high voltage networks to lower voltage networks and subsequently to the consumer. Integrating ever increasing renewable energy resources (RES) into the distribution system (DS) puts several demands on both the DS and the RES. Mains interference by the integration requires special protective devices and as the penetration becomes high, so also the demands on the grid become high. Therefore, interfacing techniques becomes very important. This article discusses the integration of renewable energy with management, protection and stability in mind for efficient power quality and system reliability.
