Unit Commitment with Primary Frequency Control Requirements for Low-Inertia Systems
(2018)
As we move towards power systems with less inertia, frequency excursions from under-frequency contingencies become more extreme and require scheduling more spinning reserves. This paper proposes an algorithm to include ...
Planeamiento de la expansión de sistemas de transmisión considerando contingencias y demanda incierta
(2009-06-01)
This paper presents a methodology and a mathematical model to solve the expansion planning problem that takes into account the effect of contingencies in the planning stage, and considers the demand as a stochastic variable ...
Sensitivity analysis by neural networks applied to power systems transient stability
(Elsevier B.V., 2007-05-01)
This work presents a procedure for transient stability analysis and preventive control of electric power systems, which is formulated by a multilayer feedforward neural network. The neural network training is realized by ...

Transmission expansion planning by using DC and AC models and particle swarm optimization
(2012-12-01)
The Transmission Expansion Planning (TEP) entails to determine all the changes needed in the electric transmission system infrastructure in order to allow the balance between the projected demand and the power supply, at ...

Optimization of Spinning Reserve in Stand-alone Wind-Diesel Power Systems
(IntechOpen, 2010)
Spinning reserve carried on synchronized units is the most effective resource available to the system operators for managing unforeseen power unbalances, such as demand fluctuations and the sudden loss of generation ...
