Coordination of ancillary services provided by decentralized power units has become one of the main grid operation challenges because system service responsibilities are increasingly being shifted to medium- and low-voltage networks. This paper describes an implementation method of considered control algorithms on real power units in German mediumvoltage systems in order to maintain the distribution...
With the development of the modern power system and the computational hardware, the industrial and research communities are more interested in simulating larger and more complicated power grids. Various iterative solvers for linear systems have been investigated with power system applications for its parallel potential in large scale linear computations. They usually require preconditioning to improve...
Accounting for system-level voltage-related operating problems represents a rather complex challenge. We first suggest that today's practice based on the use of PV curves in large power grids neither guarantees feasible power transfer nor enables the most economic utilization of real power. To overcome this problem, the use of a full-blown AC Optimal Power Flow (AC OPF) to support utilization and...
