Switching-Cycle Control For The Modular Multi-Level Converter
This new control approach provides an operation mode on which the module capacitor ripple of the modular multilevel converter (MMC) can be reduced to roughly 10% of conventional design. This means that the capacitance value of the converter can be reduced to 10% of original design if meeting the same design criteria. The capacitor rated current is ...

Islanding Detection Using Phase-Locked-Loop Small-Signal Instability For Three-Phase Power Inverters
A simple and effective anti-islanding detection is required to meet IEEE standard 1547 for every distributed generation unit. Many research papers and patents work on this issue, and there exists lots of solutions. All the existing solutions suffer the complicated design and lots of implementation procesess. Some of them tend to destabilize the gri...

Stability Analysis Suite (STASU) for DC and Three-Phase AC Electrical Power Systems
A comprehensive analysis toolset is developed for addressing the system stability at alternating-current (AC) and direct-current (DC) electrical interfaces from test and simulation results of small-signal dq and DC impedances. The software tool also includes Graphical User Interfaces (GUI) to facilitate fast and flexible data visualization and anal...
