Very complex power systems have been built to satisfy increasing demand of electrical power supply. With adding large distributed generations (DG) of high capacity to the power grid endangers the normal operation of power system and might lead to outages and system collapse. With DG increases, distribution system is also becoming more like transmission system: double or multiple feed circuits having significant changes in operation; protection system becomes more complex due to changes in system behavior and power flow under short-circuit conditions.
The convention power system protection schemes, designed to detect the fault and signal circuit breaker to isolate the fault reliably and as fast as possible, but cannot prevent from the system collapse. Nowadays, the modernized networks and telecommunications infrastructure allow optimizing the existing electrical power system operation in addition to support the future innovation. The implementation of wide area special protection schemes (SPS) or remedial action scheme (RAS) which are designed to detect the system conditions that can cause instability, overload or voltage collapse can isolate faults in the direct area and/or in areas adjacent to the fault.
Biography: Meliha B. Selak is a Power System Protection & Control Planning Specialist Engineer, who is recently retired from BC Hydro – one of the largest Utilities in North America. She has an Electrical Engineering degree from the University of Sarajevo and has over 35 years of experience in various aspects of power systems engineering including power system protection, research & development (R&D), project management and consulting on international projects; creation of computer programs for power system modeling validation and design of special protection schemes and power system emergency controls; assessment of interconnection requirements of numerous distributed and transmission connected Independent Power Producers (IPP). Prior to joining BC Hydro in 2000, she worked as a research engineer in the Power System Group at the University of British Columbia on Real-Time Power System Simulator (EMTP) and Energoinvest Corporation from Sarajevo. She has written numerous technical reports and papers on the power system subjects and she is also a paper reviewer. She has been invited keynote speaker and panelist at numerous technical conferences and symposiums. Meliha is a distinguished lecturer of IEEE PES Distinguished Lecturer Program (DLP) and a registered professional engineer in the Province of British Columbia, Canada. Also, she was a member of the Power System Relay Committee (PSRC), working on IEEE guide for “Protective Relaying of Utility-Consumer Interconnections”.
Meliha is a member of the IEEE Power & Energy Society (PES) and she was serving on the PES Governing Board as the Vice President for Chapters for 5 years, and also PES Long Range Planning (LRP) Committee. Meliha received numerous awards for her service to British Columbia’s Power and Energy community through her leadership role in IEEE Vancouver Section. She is a recipient of the 2017 IEEE PES Award for leadership in power system operation and for inspiring new engineers and women in engineering. She is also recipient of the 2010 IEEE Canada Award in recognition of dedicated and distinguished service to the profession”; and 2012 IEEE PES Vancouver Outstanding Engineer Award for contribution to the engineering profession at local and global level.
