Advanced Virtual Impedance for Power‐Sharing Improvement in Microgrids Using Different SOGI Methods: A Comparative Study

open access: yesEnergy Technology, EarlyView.
Advanced virtual impedance control integrating multiple second‐order generalized integrator (SOGI) variants—SOGI, ESOGI, MSOGI, and DSOGI—enhances power and harmonic sharing accuracy in islanded microgrids. The comparative study quantifies performance–complexity trade‐offs, demonstrating up to 65% total harmonic distortion (THD) reduction and improved ...

Improving the Characteristics of the Direct FOC Strategy in DFIG‐Based Wind Turbine Systems Using FOIDD and FOPD Controllers

open access: yesEnergy Science &Engineering, EarlyView.
This study presents a new control strategy for doubly fed induction generator (DFIG) wind turbine systems to overcome the limitations of traditional direct field control using proportional‐integral (DFOC‐PI) regulators, which are sensitive to coefficient changes and lead to low power quality.

Jitter model and signal processing techniques for pulse width modulation optical recording [PDF]

open access: yes
A jitter model and signal processing techniques are discussed for data recovery in Pulse Width Modulation (PWM) optical recording. In PWM, information is stored through modulating sizes of sequential marks alternating in magnetic polarization or in ...

High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

open access: yesEnergy Science &Engineering, EarlyView.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Off‐Grid Solar Systems: An Experimental Work and Systematic Techno‐Economic Analysis

open access: yesEnergy Science &Engineering, EarlyView.
In the study mentioned above, experimental monitoring and economic evaluation of two off‐grid PV systems were conducted using a low‐cost data logger. The results suggest that basic DC systems are economically feasible compared to grid power, but that AC systems require further cost‐cutting to achieve financial viability.
