PROJECT TITLE :

A Reliability Evaluation of Offshore HVDC Grid Configuration Options

ABSTRACT:

This paper details a technique for investigating the reliability of different offshore grid style choices for the association of offshore wind power to shore. The methodology uses a sequential Monte Carlo-based mostly technique that allows the investigation of realistic offshore phenomena, such as the weather dependency of component repair times. A range of case studies are examined for the association to shore of a cluster of way offshore wind farms and a value benefit analysis is performed that compares the capital prices, electrical losses, and reliability of every. There is found to be a transparent worth in choices that have inherent redundancy and alternative protection strategies, that avoid the utilization of expensive dc circuit breakers, that are shown to be potentially viable. It's also found that low likelihood, high impact faults, such as transmission branch failures, are a key driver behind overall grid reliability.
