Enhancement of power system security level using FACTS controllers and emerging energy storage technologies
(Nova Science Publishers, 2010)
Energy security is jointly with economy one of the most important requirements during the operation of the electric power system (EPS). However, many large blackouts happened worldwide in the last decade with serious ...
Multiple resonant controllers strategy to achieve fault ride-through and high performance output voltage in UPS applications
(The Institution of Engineering and Technology, 2018-11-13)
A control strategy to achieve fault ride-through capability and to provide high performance of the output voltage of a single-phase uninterruptible power supply (UPS) inverter is proposed in this study. This strategy ...
Thyristor-based flexible ac transmission system for controlling the vanadium redox flow battery
(Inst Engineering Technology-iet, 2013-05)
The vanadium redox flow battery (VRB) is a large stationary energy storage system; which presents high-speed response and overload capacity characteristics. The VRB produces a dc voltage between two terminals; so a power ...

Advanced fuzzy-logic-based context-driven control for HVAC management systems in buildings
(Institute of Electrical and Electronics Engineers Inc., 2020-01-01)
Control in HVAC (heating, ventilation and air-conditioning) systems of buildings is not trivial, and its design is considered challenging due to the complexity in the analysis of the dynamics of its nonlinear characteristics ...
Non-zero set-point affine feedback control of impulsive systems with application to biomedical processes
(Taylor & Francis Ltd, 2018-11)
Linear impulsive systems have been extensively studied in the last decades, mainly in the field of biomedical research. However, a proper characterisation of the equilibria of such a systems - when they are out of the ...
Evaluation of the design effects of different agropastoral systems on the diversity and density of spiders
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2017)
Sustainable agro-ecological design is challenging when the goal is self-regulation of the system. The objective of this study was to evaluate if the agropastoral design system affects the spider community, as spiders are ...
Stabilisation of grid assistance for a renewable hydrogen generation system by min-projection strategy
(Institution of Engineering and Technology, 2016-01)
Control of grid assistance is proposed in this study for a renewable hydrogen generation system of simple and robust structure. Here, the grid connection serves the dual purpose of minimising the effect of wind power ...
Time-optimal control fields for quantum systems with multiple avoided crossings
(American Physical Society, 2015-10)
We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optimal ...
Combined control of a distribution static synchronous compensator/flywheel energy storage system for wind energy applications
(Institution of Engineering and Technology, 2012-06)
The integration of wind power generation in power systems is steadily increasing around the world. This incorporation can bring problems onto the dynamics of power systems owing to the lack of controllability over the wind ...
