Including ampere measurements in generalized state estimators
(Elsevier, 2005)
Conventional state estimators (SEs) cannot take advantage of all available measurements, like currents flowing through circuit breakers and individual external injections. Current measurements are frequent at the lower ...

Steady-state model for the three-leg shunt-series ac-link power flow controller
(IET (Institution of Engineering and Technology), 2015)
Shunt-series ac links constitute a class of so-called vector switching converters, capable of controlling power flows by synthesising an adjustable series voltage. A novel steady-state model for the recently introduced ...

Assessment of conductor thermal models for grid studies
(The Institution of Engineering & Technology, 2007)
: Existing EMS applications resort to static network models built upon constant resistances whose values are specified beforehand. However, the steady-state thermal balance of overhead conductors requires that ohmic ...

A new technique for short-term reliability assessment of transmission and distribution networks
(IEEE Xplore, 2006)
This paper proposes a new methodology for shortterm (24 hours) reliability assessment of transmission and distribution networks, including detailed substations models. Substations are first considered as single electrical ...

Distributed consensus-based secondary control of multi-terminal DC railway systems
(Elsevier, 2023-06)
Electrification of the transportation sector is one of the main pillars of the future decarbonized society. In this context, high-speed railway corridors are expected to reduce as much as possible their environmental impact ...

Substation Automation. Local Aids to the Power Distribution Network Control
(International Federation of Automatic Control, 1986)
This paper presents an automatism for electrical distribution substation control. Its objective is to perform a local contribution to the whole power system control. It has been implemented using a low-cost eight bit ...

A Hybrid Procedure Including Subtransmission Systems and Substations for Reliability Assessment
(IEEE Xplore Digital Library, 2013)
A new procedure focused on reliability analysis of subtransmission systems supported by the state enumeration technique is presented. This new methodology is conducted in three stages. First, a classical state enumeration ...

Integrated simulation of electromechanical and thermal dynamics of voltage source converters
(Elsevier, 2024-01)
This paper proposes a simplified yet accurate enough thermal model of Voltage Source Converters (VSC), aimed at circumventing the high computational cost of existing models, which prevents their use in electromechanical ...

A Comparison Between Kalman Filters and STDFT for Harmonic Estimation in Power Systems
(World Scientific and Engineering Academy and Society (WSEAS), 2005)
This paper presents a comparison between Kalman filter and the running DFT for the computation of harmonics in power systems applications. The performance of both filters is compared for events like voltage dips or those ...

The Spanish Experience: Squeezing Line Ampacities Through Dynamic Line Rating
(Institute of Electrical and Electronics Engineers, 2023-01)
Dynamic Line Rating (DLR), also known in some instances as real-time thermal rating , is becoming a key component of modern energy management systems for transmission system operators (TSOs) or independent system operators ...
