The management of uncertainties is a challenging task for reliable and secure operation of power systems. The uncertainties come from multiple sources, including the forecast errors of wind power and load, the forced outage of generating units, loss of tra ...
The optimal power-flow problem (OPF) has always played a key role in the planning and operation of power systems. Due to the non-linear nature of the AC power-flow equations, the OPF problem is known to be non-convex, therefore hard to solve. Most proposed ...
The management of voltage and reactive power control sources considering the voltage stability is a challenging issue for secure operation of power systems. Generally the analysis of the stability margin is performed using P V and V Q based approaches. Thi ...
Voltage stability imposes important limitations on the power systems operation. Adequate voltage stability margin needs to be obtained through the appropriate scheduling of the reactive power resources. The main countermeasures against voltage instability ...
Voltage stability imposes important limitations on the power systems operation. The system should be operated with an adequate voltage stability margin by the appropriate scheduling of reactive power resources and voltage profile. The main countermeasures ...
Optimization is important in science and engineering as a way of finding ”optimal” situations, designs or operating conditions. Optimization is typically performed on the basis of a mathematical model of the process under investigation. In practice, optimi ...
Inter-zonal trading in multi-area power system (MAPS) improves the market efficiency and the system reliability by sharing the resources (energy and reserve services) across zonal boundaries. Actually, each area can operate with less reserve resources than ...
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 proposed using centralized and decentralized implementations. The proposed for ...
We propose a new decentralized control scheme for DC Islanded microGrids (ImGs) composed by several Distributed Generation Units (DGUs) with a general interconnection topology. Each local controller regulates to a reference value the voltage of the Point o ...
The reserve is a service traded in the market to counteract unpredictable changes in system conditions. The efficient market-clearing procedure relies on economic criteria while maintaining the system security by means of a proper reserve management progra ...
