Results on distributed state estimation for LTI systems facing communication failures
(Elsevier B.V., 2020)
We address distributed estimation of the state of a linear plant by a set of agents. The problem is cast in a setting where the communication capabilities of an agent might be deactivated from time to time, due to failures ...

Two-level optimisation and control strategy for unbalanced active distribution systems management
(Institute of Electrical and Electronics Engineers Inc., 2020)
This article proposes a new approach to the operation of unbalanced Active Distribution Sys- tems (ADS) using an economic dispatch optimisation model for Active Distribution Systems Management (ADSM). The model proposes ...

Development of cost-functions for the remuneration of new ancillary services in distribution networks
(Institute of Electrical and Electronics Engineers Inc., 2021)
The higher penetration of intermittent and volatile Distributed Renewable Energy Sources (DRES) in distribution grids is gradually replacing the bulk synchronous generators (SGs) of the transmission system, resulting in ...

A comparison of residual demand models for oligopolistic markets
(2005)
In many pool-based electricity markets two types of generating companies coexist, namely price-taking and leader companies. In this context, the optimal bidding of a leader company, and consequently the market ...

Open-Phase Fault-Tolerant Direct Torque Control Technique for Five-Phase Induction Motor Drives
(Institute of Electrical and Electronics Engineers, 2017-02)
Direct torque control (DTC) has been widely used as an alternative to traditional field-oriented control (FOC) methods for three-phase drives. The conventional DTC scheme has been successfully extended to multiphase ...

Influence of the wind variability on the calculation of dynamic line rating
(Elsevier, 2022-10)
This paper presents a novel technique to calculate the ampacity of an overhead transmission line in real time, considering the dynamic evolution of the conductor temperature. In case this method cannot be applied due to ...
