RATIONAL USE OF CONNECTED CAPACITIES IN PURPOSE OF MORE ELECTRICITY EFFICIENT POWER DISTRIBUTION NETWORK
(AIM, June 2019)Distribution System Operator (DSO) is obliged to provide the contracted power to the system user. The use of the distribution capacity below the contracted connection power causes the inefficient engagement of the available ... -
Reactive operation for Smart LV Grids
(AIM, June 2019)The increased integration of distributed energy resources within distribution systems increases the necessity for operators to monitor and control low-voltage grids in order to maintain the stability of the distribution ... -
Reactive Power Flow over System Boundaries in the Distribution Grid
(AIM, June 2019)The focus of this paper is the reactive power balance. The question, to what extent the reactive power flows at the system boundaries can be influenced, will be covered. On the one hand at the interface between transmission ... -
Reactive Power Optimizaztion Method Incorporating Economic And Action Number Constraints of Control Devices
(AIM, June 2019)The access of large-scale high penetration photovoltaic to the distribution network makes the direction of power flow frequently change, resulting in frequent switching of reactive power regulating equipment and frequent ... -
Reactive Power Provision by Means of Flexible Industry Consumers
(AIM, June 2019)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 ... -
Real case islanding detection on the Distribution network by using microPMU units
(AIM, June 2019)Distributed Generation (DG) is gradually increasing in Distribution Grid, both in LV, MV and HV, creating new challenges to utilities. One of them is the capacity to detect an unwanted islanding operation. As seen in recent ... -
