This paper presents a feedback/feed-forward control strategy to improve the voltage balancing of modular multilevel converters (MMCs) under unbalanced grid conditions. The inclusion of a feed-forward compensation improves ...

Currently, a worldwide tendency of decentralization of electric energy production (called Distributed Generation) is observed, where small generators – sometimes composed by synchronous machines – are connected mainly ...

A new control strategy for static compensators (STATCOMs) operating under unbalanced voltages and currents is presented in this paper. The proposed strategy adopts a state observer (software sensor) to estimate ac voltages ...

A new adaptive control strategy, intended to improve the ride-through capability of HVDC systems under unbalanced network conditions and parameter uncertainties, is introduced. The proposed strategy resorts to a model ...

In modern industries, transducers and measurement systems have been largely applied for equipment monitoring. In this context, three-phase induction motors (TIMs) are the main focus of predictive maintenance due to their ...

This thesis addresses the main issues regarding the operation of full power converters wind turbines connected to the grid under balanced and unbalanced voltage sags. In the past, the grid codes allowed wind turbines to ...

This paper investigates the major similarities and discrepancies of three important current decompositions proposed for the interpretation of unbalanced and/or non linear three-phase four-wire circuits. The considered ...
