Methodology for Tuning MTDC Supervisory and Frequency-Response Control Systems at Terminal Level under Over-Frequency Events
(MDPI, 2020-06-01)
This paper proposes a methodology for tuning a supervisory and frequency-response outer loop control system of a multi-terminal direct current (MTDC) grid designed to transmit offshore wind energy to an onshore AC grid, ...
Circuit Breaker Failure Protection Strategy for HVDC Grids
(MDPI, 2021-07-18)
HVDC grids demand the fast and reliable operation of the protection system. The failure of any protection element should initialize a backup protection almost immediately in order to assure the system’s stability. This ...
Estimation of the Heat Loss Coefficient of Two Occupied Residential Buildings through an Average Method
(MDPI, 2020-11-02)
The existing performance gap between the design and the real energy consumption of a building could have three main origins: the occupants’ behaviour, the performance of the energy systems and the performance of the building ...
Single-ended limiting inductor voltage-ratio-derivative protection scheme for VSC-HVDC grids
(Elsevier, 2023-05)
Single-ended protection systems present the characteristics needed to fulfil the restrictive speed requirement related to high voltage direct current grids. This paper proposes a novel single-ended protection algorithm ...
Stochastic Coordinated Management of Electrical–Gas–Thermal Networks in Flexible Energy Hubs Considering Day-Ahead Energy and Ancillary Markets
(MDPI, 2023-07-07)
This paper presents an optimal operation framework for electrical, gas, and thermal networks in the presence of energy hubs (EHs), so that EHs can benefit from day-ahead ancillary and energy markets. Therefore, to consider ...
Tension and Ampacity Monitoring System for Overhead Lines
(IEEE, 2013-01-01)
Real time monitoring allows the determination of the line state and the calculation of the actual rating value. The real time monitoring systems measure sag, conductor tension, conductor temperature or weather related ...
Optimized Energy Management Strategy for Wind Plants with Storage in Energy and Reserve Markets
(IOP Publishing, 2019-05-21)
This paper addresses the joint operation of wind plants with energy storage systemsin multiple markets to increase the value of wind energy from an economic and technical point of view. The development of an optimized ...
A system approach to harnessing wind energy in a railway infrastructure
(IEEE, 2018-12-30)
This paper focuses on a system approach aimed at harnessing the wind potential in a railway infrastructure. The key aspect of the proposed system lies in using the mass of air displaced during the movement of a train along ...
Analysis of Local Measurement-Based Algorithms for Fault Detection in a Multi-Terminal HVDC Grid
(MDPI, 2019-12-17)
One of the most important challenges of developing multi-terminal (MT) high voltage direct current (HVDC) grids is the system performance under fault conditions. It must be highlighted that the operating time of the ...
Mathematical development of an average method for estimating the reduction of the Heat Loss Coefficient of an energetically retrofitted occupied office building
(Elsevier, 2019-03-07)
The performance gap between the design energy consumption of buildings and their real energy consumption has three main sources: the energy systems’ performance, the users’ behaviour and the buildings’ envelope performance. ...
