Linear Power Flow Analysis and Applications
In the accelerated environments of today’s
electric energy markets, fast analyses of power flows are a must.
Emerging real-time and day-ahead markets require that analysis of
infrastructure capacity be performed in a compressed timeframe.
In this context, approximate but fast and consistent power flow
solutions are preferred over accurate but unwieldy ones. Hence, the
increasing popularity of linear approximations to the power
flow. The reason for widespread use may have to do with the
fact that linear methods are much easier to apply, are not
subject to convergence issues, and require less data.
In this introductory course, learn about the
technology of linear power flows and apply them to real-world
practical problems. Use this technology in applications such
as anticipatory analysis of pricing and demand signals,
transactional analysis of power interchange and delivery,
transmission loading relief and feasibility analysis.
In addition, learn about the limitations to these methods and the
pitfalls to watch out for when applying these methods. Come away
with a working knowledge of the technology of linear power flows.
The course is oriented to be of most benefit to
- Transmission Operators
- Reliability Operators
- Generator Operators
- Market Operators
- Operations and Planning Engineers
To ensure the quality and timeliness of our courses, Pterra asks
participants to provide feedback and to rate each course. This allows
to adjust to the changing needs of the industry. Assessment
ratings are made on a scale of 5 with highest being 5.0. Ratings
are applied to individual topics, individual speakers and instructors,
and aspects of course presentation such as materials, notes and interaction.
The training is presented in a classroom format, using lectures,
hands-on exercises and review tests. In the lectures,
concepts, methods and techniques for each learning objective are
presented, with provision for Q&A sessions to address specific
questions. The exercises provide for a basis to apply
the concepts in real-world simulation software, and interpret the
results from a physical standpoint. The test reviews
determine if there is sufficient retention of the course material to
support the award of CE credits.
The course is presented over
three days with two sessions per day. Each session comprises of 3
classroom hours. Participants receive bound Course Notes
which contain a copy of the material presented in the lectures,
including supplementary material for reference, description of the
exercises and answer sheets for the exercises.
The exercises are presented with an overview and explanation of
the sample system and provided data, a list of questions and
space for the participants to enter responses, comments and
Computers will be provided for course
participants. Participants who wish to bring their own laptops with
their own licensed analytical
software may do so. Pterra's instructors can provide coaching for most

The course will be held at Pterra's Training Facility in Albany, New
York, located 5 minutes from Albany International Airport on Wolf
Road. Over 20 hotels and restaurants within 10 minutes make this
an accessible location. Also, the location is within a day's
driving distance from anywhere in the Northeast US and eastern Canada.
The course is also available for presentation at sponsored venues.
