Casavola, A.; Franze, G.; Menniti, D.; Sorrentino, N. Clean Electrical Power, 2009 International Conference on, 2009
In this paper a control strategy based on predictive control ideas is proposed for reconfiguring on-line the on-load tap changer (OLTC) voltage set-point in electrical medium voltage (MV) power grids in the presence of distributed generation (DG). The idea is that an active management of the set-point can be effective for maintaining relevant system variables within prescribed operative constraints in ...
Le Fu; Pal, B.; Cory, B. Power Engineering Society General Meeting, 2006. IEEE, 2006
A new voltage control method, namely virtual voltage coordinated control, for transformer on-load tap changer and static compensator is presented. This coordinated control methods consists of two major parts, virtual voltage calculation and bad data detection. The nice properties of conventional tap changer control are preserved by keeping the conventional dead band and time delay mechanism. The capacity of static ...
O'Gorman, R; Redfern, M.A.; Al-Nasseri, H. Future Power Systems, 2005 International Conference on, 2005
This paper discusses the contribution to both voltage control and increasing the loading on radial distribution feeders that can be achieved by allowing distributed generation to participate in voltage control. Distributed generators of many designs are capable of altering their active and reactive power outputs and can therefore make significant contribution to control of voltage. However, current practice requires that ...
Kamwa, I.; Grondin, R.; Loud, L. Power Engineering Review, IEEE, 2001
A time-frequency-based approach for contingency severity ranking and rapid stability assessment is described. The aim is to classify correctly all single or multiple contingencies that may result in loss of voltage or frequency stability in the first 20 s following the last disturbing action. We start by selecting a number of strategic monitoring buses where the phasor measurement units are ...
Lettas, N.; Dagoumas, A.; Papagiannis, G.; Dokopoulos, P. Power Tech, 2005 IEEE Russia, 2005
The deregulation of the electricity markets and the advances in the power generation technologies together with financial and environmental concerns have positioned distributed generation as a very promising power generation alternative. Scope of this paper is to investigate some problems related to voltage quality when DG is implemented in a weak distribution network. The case under study is a 20 ...
