Efficiency Comparison of DC and AC Coupling Solutions for Large-Scale PV+BESS Power Plants

Efficiency of large - scale DC - networks

DC-networks offer desirable properties for anonymous communication, but a practical implementation for large networks is challenging. Other approaches like Tor exist and are easier to use in large networks, but they do not provide strong anonymity. This thesis describes a design for a DC-network implementation that targets large networks. It does not offer new methods to counter attacks, but it...

A Novel Multilevel Ac–Dc-Ac Converters with Improved Efficiency

Multilevel inverter technology has emerged recently as a very important alternative in the area of high power medium-voltage control and also for improving the total harmonic distortion by reducing the harmonics. Generally, the poor quality of voltage and current of a conventional inverter fed induction machine is obtained due to the presence of harmonics and hence there is a significant level ...
