This paper discusses the impact of marked-based flexibility operation on distribution grids on both MV and LV level. Based on the gained experience in three research projects eBADGE, hybridVPP4DSO and IEA HPP Annex42, it is discussed how far market participation of flexibility resources in the distribution grid can cause grid congestions under consideration of current Austrian network planning practices...
During the last decades the electric vehicles (EVs) technologies are developing rapidly which may lead to a significant penetration level in the mobility market in the near future. As a consequence of these high penetration levels, power grids, especially on the low voltage level, might face a number of technical problems. These can be transformer and cables overloads, feeder congestions and especially...
A key aspect to the future development of Smart Grids is the cooperation between multiple grid components. If this cooperation is to be included into grid simulations however, the limit is often reached when only one tool can be used for the simulations. This paper describes a framework for the simulation of power networks and their components including DIgSILENT/PowerFactory and MathWorks MATLAB/Simulink...
Open source solutions will enable the acceptance and usage of open standards for smart grid applications. The aim of this work is to demonstrate the possible usage of a distributed automation system for controlling electrical power systems with Distributed Energy Resources (DER). The control approach is based on the IEC 61499 reference model for distributed control system and its open source solution...
An advanced approach for voltage control in distribution networks is introduced that allows the number of DERs (Distributed Energy Resources) connected to a distribution network to be increased. This contribution discusses the approach comprehensively with simulation results and guidelines for practical implementations. The methodology presented attains the objective of controlling the voltage in...
