Sine-cosine optimization approach applied to the parametric estimation in single-phase transformers by considering voltage and current measures
(2021-05-25)
In this article, a combinatorial optimization approach for estimating the electrical parameters in single-phase distribution transformers by considering voltage
and current measures is presented. A nonlinear programming ...
Recursive Convex Model for Optimal Power Flow Solution in Monopolar DC Networks
(2022-10-05)
This paper presents a new optimal power flow (OPF) formulation for monopolar DC networks using a recursive convex representation. The hyperbolic relation between the voltages and power at each constant power terminal ...

This research analyzed productivity in the formation of citizen skills in engineering education. The population (57,520 students) included 92 Colombian undergraduate engineering degree programs (industrial, mechanical, ...
Full State Feedback of DC-Motor Position and Speed Control Using LQR and Kalman Filter
(2022)
DC motors are used in various industrial, robotic and motion control applications, and generally angular position and speed are used as the main control variables. This paper presents the design of an LQR controller with ...
Electricity retail market and accountability-based strategic bidding model with short-term energy storage considering the uncertainty of consumer demand response
(2022)
Electricity retailers participate in electricity markets as intermediaries between wholesale and retail markets. They acquire energy on the wholesale side by participating in next-day markets and the pool of power. On the ...
Adaptive Sensorless PI+Passivity-Based Control of a Boost Converter Supplying an Unknown CPL
(2022)
This paper presents an adaptive control to stabilize the output voltage of a DC–DC boost converter that feeds an unknown constant power load (CPL). The proposed controller employs passivity-based control (PBC), which assigns ...
