Impedance sensitive STATCOM control for systems supported by renewable generation (2014)
Conference Proceeding
Rose, C. J., Sumner, M., Thomas, D. W., & Christopher, E. (in press). Impedance sensitive STATCOM control for systems supported by renewable generation.

Reactive power control is known to be an effective means of controlling voltage; however, for optimal performance, the system reactance must be known. Power systems with high re-newable energy penetration have been known to have voltage stability iss...

Marine power distribution system fault location using a portable injection unit (2014)
Journal Article
Jia, K., Bi, T., Liu, B., Christopher, E., Thomas, D. W., & Sumner, M. (2015). Marine power distribution system fault location using a portable injection unit. IEEE Transactions on Power Delivery, 30(2), https://doi.org/10.1109/TPWRD.2014.2364259

A portable injection unit for Active Impedance Estimation (AIE) is built and tested in a DC zonal marine power distribution system to provide useful information for system protection and restoration. The portable unit generates current “spikes” and i... Read More about Marine power distribution system fault location using a portable injection unit.

Power flow control for power and voltage management in future smart energy communities (2014)
Conference Proceeding
Fazeli, A., Sumner, M., Christopher, E., & Johnson, C. M. (2014). Power flow control for power and voltage management in future smart energy communities.

The Community Power Flow Control (CPFC) Algorithm has been proposed as a technique for managing electrical power and energy within small communities. The CPFC manages the resources in the community (DSM, energy storage, RES) in order to control the c...

Intelligent impedance based fault-location for zonal power systems (2014)
Conference Proceeding
Rose, C. J., Thomas, D. W., Sumner, M., Christopher, E., & Lopez Arevalo, S. (2014). Intelligent impedance based fault-location for zonal power systems.

A laboratory based demonstrator has been constructed to study the Active Impedance Estimation (AIE) technique as a means of locating faults on a power system. The demonstrator has been used to verify results from simulation experimentally. The AIE sy... Read More about Intelligent impedance based fault-location for zonal power systems.

Advanced DC zonal marine power system protection (2014)
Journal Article
Jia, K., Christopher, E., Thomas, D. W., & Sumner, M. (2014). Advanced DC zonal marine power system protection. IET Generation, Transmission and Distribution, 8(2), https://doi.org/10.1049/iet-gtd.2013.0139

A new Active Impedance Estimation (AIE) based protection strategy which is suitable for utilization in a DC zonal marine power distribution system is presented. This method uses two triangular current "spikes" injections for system impedance estimati... Read More about Advanced DC zonal marine power system protection.
