Integration of distributed energy resources in the operation of energy management systems

The presence of distributed generation poses new challenges in the management and operation of electrical grids. Distributed generation (wind, combined heat and power, etc.) already accounts for 20% or more of total generation in some electric utilities and this figure is constantly increasing worldwide. TSOs, DSOs and energy markets need to have some visibility on a large number of small power injections. This paper presents solutions to adapt classical tools and processes so that energy management systems can efficiently supervise and manage distributed generation.
