Abstract

A decentralized supply of electrical power based on renewable energies paves the way to a sustainable power supply
without nuclear energy and without the emission of greenhouse gases. This energy transition (Energiewende) entails
challenges regarding the provision of Ancillary Services (AS), associated with intermittent in-feed of Distributed Energy
Resources (DER) into the distribution grids. In this paper, the demand, potentials, and technical requirements for AS
provision in Germany, especially in the state of Lower Saxony, are discussed. These aspects are considered from multiple
perspectives across all voltage levels. Beginning with a steady-state analysis that focuses on the transmission grid, an
expected increment in voltage violations and line congestions is revealed. Counteracting the resulting technical limit
violations requires consideration of distribution grid flexibilities among others. To address this emerging demand, the
potentials for the provision of AS by components in the distribution grids are identified. However, technical concepts are
also required to exploit the potential, as DER in-feed has significant impact on the functionality of conventional protection
systems. The analysis in this paper indicates the need for development of concepts to provide AS in the distribution grid
and detailed technical requirements within a holistic simulative approach.
