Abstract:
|
The operation of distributed power generation
systems under grid fault conditions is a key issue for the
massive integration of renewable energy systems. Several
studies have been conducted to improve the response of such
distributed generation systems under voltage dips. In spite of
being less severe, unbalanced fault cause a great number of
disconnections, as it may produce the injection of unbalanced
currents that can easily conduct to the tripping of the
converter. In this paper a current control strategy for power
converters able to deal with these grid conditions, without
exceeding the current ratings of the converter is introduced.
Moreover, a novel flexible algorithm has been proposed in
order to regulate easily the injection of positive and negative
currents for general purpose applications. |
