A MIQP model for optimal location and sizing of dispatchable DGs in DC networks
(2020-08-27)
The allocation and dimensioning of distributed generators (DGs) in direct current (DC) power grids were addressed in this study by using a mixed-integer quadratic programming (MIQP) formulation. The MIQP model corresponded ...
Optimal Placement and Sizing of Wind Generators in AC Grids Considering Reactive Power Capability and Wind Speed Curves
(2020-04-08)
This paper presents an optimization model for the optimal placement and sizing of wind turbines, considering their reactive power capacity, wind speed, and demand curves. The optimization model is nonlinear and is focused ...
Standard passivity-based control for multi-hydro-turbine governing systems with surge tank
(Elsevier Inc., 2020)
This paper addresses the problem of control design for hydro-turbine governing systems with surge tanks from the perspective of standard passivity-based control. The dynamic model of a synchronous machine is considered in ...
Fuzzy logic methodology to study the behavior of energy transformation processes based on statistics T2and Q
(2020-10)
In the processes of energy transformation, to carry out an adequate follow-up of the process parameters represent an opportunity to propose strategies to improve the processes' performance. For this reason, it is essential ...

(2020-12-24)
This document contains the chassis design for an autonomous electric vehicle. First, a fatigue failure analysis should be done to the underside of the chassis under fluctuating loads. Subsequently, the methodology of the ...
Control by second order sliding modes for a double-fed induction generator for a wind turbine
(2020)
In recent years, the consumption of electrical energy in the world has increased, increasing the construction of power plants that operate with fossil fuels, which emit a large amount of CO2. Due to this polluting process, ...
A New Iterative Power Flow Method for AC Distribution Grids with Radial and Mesh Topologies
(2020-11-25)
This brief discusses the classical problem of power flow analysis in alternating current (ac) distribution networks through Taylor series expansion. The main advantage of this approach is that it can work with radial and ...
