Abstract: The electric power system has been
experiencing a shift in its generation resource mix resulting from the
retirement of conventional base load synchronous resources and the
integration of a more diverse fleet of smaller sized resources with
varying generation characteristics. As this transformation continues,
there is a fundamental shift in the operational characteristics of the
power system as a whole and thus potential reliability implications. In
2014, the North American Electric Reliability Corporation (NERC) created
a task force on Essential Reliability Services (ERS) to identify the
necessary operating characteristics to assure reliable operations of the
North American electric grid. By 2015 frequency, voltage, and net
demand ramping variability were recognized as the three essential
building blocks of reliability. In December 2016, a paper on ERS
sufficiency guidelines include frequency response, voltage limits, and
ramping models that tend to vary by particular area and Balancing
Authority. The ERS task force also studied the potential impact of a
substantial penetration of distributed energy resources (DERs) that, in
aggregate, could impact the reliability of the BPS. This industry
presentation will focus on the measures identified by the ERS working
group, and highlight the results from analysis performed using three
years of historical data and three years of forward looking data.
Additionally, an overview of the analysis performed by DER task force
will be provided.
Bio:Dr. Nicole Segal is currently with the North
American Electric Reliability Corporation (NERC). She is an Engineer in
the Reliability Assessments department under Thomas Coleman. Dr. Segal
performs reliability assessments and system analysis. She recently began
co-leading NERC’s Essential Reliability Services Working Group. Dr.
Segal completed her PhD in Electrical Engineering and concentrated on
electric power distribution optimization, automation, and control
systems and had a research focus on the effects of integrating
renewables into the distribution grid. While pursuing her PhD, Nicole
developed and delivered automated capacitor placement software for PPL
Electric Utilities under a Department of Energy Grant. In addition to
research activities at her university, she also volunteered and
performed out-reach education to non-engineering students. Prior to her
PhD, Nicole was with PJM in Norristown Pennsylvania where she was a
Planning Engineer and managed short circuit analysis for the Generation
Interconnection Department. Nicole has her Bachelors of Science, Masters
of Science and her PhD in Electrical Engineering from Drexel
University.
