The current electric power system was not designed for two-way electricity flow. Instead, it was developed under the assumption that electricity would be produced at large, central generating stations and then delivered out to homes and businesses. But today, distributed energy provides a genuine alternative to that longstanding assumption. The challenge now is finding ways to make the new system work efficiently and inexpensively while integrating into the current infrastructure.
It is for this reason that interconnection and its technical and policy support development is important. Work in this area includes:
- Developing distributed generation-electric power system interconnection interface requirements
- Determining the effect of interconnection on the design of distributed generation power electronics
- Determining the effect of increased distributed generation penetration and interconnection on the utility network
- Developing, building, and testing a safe and reliable interconnection interface.
