Summary: This paper presents a study on the DC fault transient of a meshed DC grid integrated with high-temperature superconducting (HTS) HVDC cables for offshore wind power integration. A four-terminal meshed DC grid model with a +/-100 kV DC voltage rating is developed, and DC circuit breakers (DCCBs) are employed to manage DC cable faults. Through fault scenario studies with different fault locations and protection delays, it is found that the faults on the faulted cable do not affect the functioning of other healthy cables and that the long delay of DC fault protection does not result in excessive fault current and the quenching of healthy cables. Extensive simulations in PSCAD/EMTDC software validate the research findings.

Summary: Modern power systems with power electronic converters require precise control of current injections. Conventional grid codes fail to provide optimized voltage support during faults. This paper analyzes the grid voltage support operation and proposes improvements to maintain the grid voltage close to the nominal value. Two alternative grid codes are proposed, which inject only reactive power but achieve near-optimal results.

Summary: The emergence of power electronics has led to the widespread adoption of dc grids, which are known for their improved performance and efficiency. However, fault isolation poses a significant challenge for dc grids due to the absence of current zero-crossing. This article introduces a novel silicon-controlled-rectifier-based bidirectional dc solid-state circuit breaker that not only isolates faulty sections but also provides soft reclosing capability to reduce stress on the breaker and current feeding components, with negligible heat loss by surge suppression devices during reclosing. The effect of component values on circuit-level considerations is analyzed through derived equations, and simulation and scaled-down experimental results are presented to verify the breaker's operation under various conditions.

Summary: A hybrid modulation strategy is proposed in this paper to mitigate the inherent problem of current distortion at zero crossings in three level Vienna rectifier. By injecting a calculated minimal amount of reactive current along with zero sequence, the risk of overmodulation at higher modulation indices is avoided, significantly reducing the reactive current compared to existing solutions. With this method, the Vienna rectifier can operate in a wide range of power factors without compromising the quality of the source currents.
