Reactive Power Provision by Means of Flexible Industry Consumers

Abstract

Due to the reduction of conventional electricity generation within the German grid new challenges arise. One of those challenges is how reactive power can be provided for the voltage regulation of the grid. A possible way to provide reactive power is the utilization of free converter capacities in the lower voltage levels. This paper focuses on the provision of reactive power by means of flexible industry consumers in the LV-network. The characteristics of an existing factory, which is intended for scientific research, at Technische Universität Darmstadt are used as an example of a flexible industry consumer. The reactive power provision capability for different levels of grid penetration with flexible factories is evaluated. In addition to the reactive power provision potential, the impact on the local distribution grid of the campus is analyzed.
