A Discrete-Continuous PSO for the Optimal Integration of D-STATCOMs into Electrical Distribution Systems by Considering Annual Power Loss and Investment Costs
(2022-07-14)
Currently, with the quick increase in global population, the energetic crisis, the environmental problematic, and the development of the power electronic devices generated the need to include new technologies for supporting ...
LQR-Based adaptive virtual inertia for grid integration of wind energy conversion system based on synchronverter model
(2021-03-06)
This paper proposes adaptive virtual inertia for the synchronverter model implemented in a wind turbine generator system integrated into the grid through a back-to-back converter. A linear dynamic system is developed for ...
Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach
(2021-09-24)
The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck ...
Trade-Off Asymmetric Profile for Extended-Depth-of-Focus Ocular Lens
(2022-02-19)
We explore the possibility of extending the depth of focus of an imaging lens with an
asymmetric quartic phase-mask, while keeping the aberration within a relatively low level. This can be intended, for instance, for ...
A Framework for Water Security Data Gathering Strategies
(2022-09)
At the international level, the term “water security” (WS) has gained increasing attention in recent decades. At the operational level, WS is assessed using tools that define the concept using a variety of dimensions and ...
A mixed-integer convex approximation for optimal load redistribution in bipolar DC networks with multiple constant power terminals
(2022)
This paper proposes a mixed-integer convex model for optimal load-balancing in bipolar DC networks while considering multiple constant power terminals. The proposed convex model combines the Branch and Cut method with ...
A method for evaluating the quality service of a user unit in a water service company in Colombia
(2020)
This research study proposes a method to evaluate the quality of service of a user service unit in a water service company in Colombia. Based on the theoretical foundation associated with the quality of service and the Six ...
