This paper introduces a new transformerless converter topology for Multiphase-Based Wind Energy Conversion Systems (WECSs). In this topology, a twelve-phase induction generator is integrated to the grid using dual Nine-Switch Converters (NSCs) connected in series forming a high voltage cascaded dc-link. For this generator phase number, this topology reduces the total number of semiconductor devices...
Due to the large increase in number of installed high power renewable energy generating systems such as wind energy power plants, one of the important evolving requirement is riding through the fault at low or zero voltage. In this paper, static synchronous series compensator is employed in power systems with high penetration of renewable energy units to achieve low voltage ride through capability...
Renewable energy sources, such as offshore wind farms, require high voltage gains in order to interface with power transmission networks. These conversions are normally made using bulky, complex, and costly transformers and high-voltage ac-dc converters with unnecessary bidirectional power flow capability. Multiple modules of single-switch single-inductor dc-dc converters can reach high gains without...
