High impedance fault modeling and location for transmission line
(2021-04-07)
A fault in a power system generates economic losses, security problems, social problems and can even take
human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure
time ...
Nonlinear analysis and control of a reaction wheel pendulum: Lyapunov-based approach
(Elsevier B.V., 2019)
This paper presents a nonlinear analysis, control, and comparison of controllers based on the dynamical model of the reaction wheel pendulum (RWP) in a tutorial style. Classical methodologies such as proportional integral ...
Economic dispatch in DC Microgrids considering different battery technologies: A Benchmark Study
(2020-11-25)
Large penetration of variable renewable sources and electronic loads put short-term stress on microgrids. Energy storage systems account for a reliable way to mitigate these issues. However, depending on the electro-chemistry, ...
Output Voltage Regulation for DC-DC Buck Converters: A Passivity-Based PI Design
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents a global tracking passivity-based proportional-integral (PI) control for output voltage regulation of a DC-DC Buck converter. The proposed controller is based on passivity formulation since DC-DC Buck ...
A mixed-integer second-order cone model for optimal siting and sizing of dynamic reactive power compensators in distribution grids
(2022-06-20)
The problem of the optimal placement and sizing of dynamic reactive power compensators in AC distribution networks is addressed in this paper from convex optimization. The exact mixed-integer nonlinear programming (MINLP) ...
Global stabilization of a reaction wheel pendulum: A discrete-inverse optimal formulation approach via a control lyapunov function
(2020-10-26)
This paper deals with the global stabilization of the reaction wheel pendulum (RWP) in the discrete-time domain. The discrete-inverse optimal control approach via a control Lyapunov function (CLF) is employed to make the ...
Passivity-Based Control for Hydro-Turbine Governing Systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper an interconnection and damping assignment passivity-based control (IDA-PBC) applied to the hydro-Turbine governing systems (HTGS) is proposed to regulate the relative deviation of turbine speed in single ...
SCES Integration in Power Grids: A PBC Approach under abc, αβ0 and dq0 Reference Frames
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents an integration of three-phase supercapacitor energy storage (SCES) in power grids via passivity-based control (PBC) theory under different reference frames. The SCES systems have the possibility to ...
VSC with direct PI power control for frequency compensation in a microgrid: A PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2019)
The power systems with low inertia such as microgrids require advanced control strategies to improve their performance. These type of grids use voltage source converters to interconnect renewable energy sources and storage ...
Wirtinger's Calculus for the Load Flow in Power Distribution Grids
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper shows a Wirtinger's-Calculus based loadflow methodology for power distribution grids. This approach allows to obtain an algorithm which works directly on the complex domain maintaining some useful symmetries and ...
