The microgrid concept was proposed as a way to facilitate the integration of distributed renewable energy resources. However, due to the use of distributed energy resources (DERs) microgrids face new protection challenges that need resolved. One of those challenges is that traditional protection methods, such as overcurrent protection, cannot be used mainly because of low fault currents, bi-directionality...
This paper addresses the protection of a high voltage direct current (HVDC) transmission system, utilizing the modular multilevel converter (MMC) topology in addition to incorporating a hybrid transmission corridor (transmission line including overhead line and cable sections). A solution is proposed for identifying the section within which a dc fault is located for the purpose of maintaining power...
Identifying the exact fault location within a HVDC system is critical in order to perform rapid system restoration for enhanced system reliability and operation. A method is proposed to locate faults using transient system data generated by the fault with system measurements at the HVDC converter terminals. The proposed method can locate temporary and permanent faults on a hybrid HVDC-VSC system,...
The potential to harness offshore wind power and transmit that energy to shore is of widespread interest in the electric power and energy industry sector, as well as within U.S. government agencies such as the Department of Energy. Studies are currently being conducted to find optimal placement of offshore wind turbines along the perimeter of the United States coast lines, and evaluations of current...
