Voltage control service is a critical ancillary service used by all system operators for secure
and reliable operation of the power system. It must be continuously active. On-going …

This paper presents a “marginal equivalent” decomposition algorithm that partitions a linear
programming problem into subproblems and coordinates their solutions by exchanging the …

Electrical power system operators (SOs) are free to realize grid operations according to their
own strategies. However, because resulting power flows also depend on the actions of …

This paper studies the multi-area voltage and reactive power management regarding the
voltage stability. In this respect, the maximization of effective reactive power reserve is …

To deal with the increasing load demand and environmental effects of conventional power
devices, power system has become an enlarged complex network with the integration of …

Scheduling voltage and reactive power is one of the major problems and concerns of the
Transmission System Operators (TSOs) especially after deregulation of power market. Due …

Distributed optimization methods promise to coordinate power system operators to improve
the overall grid operation. This paper analyzes and extends existing distributed optimization …
