Variable Renewable Integration: Power System Flexibility and Operating Under Uncertainty

Aidan Tuohy, Electric Power Research Institute

Friday, April 18, 2014, 3:30pm

Spanos Auditorium

This seminar is part of the Jones Seminars on Science, Technology, and Society series.

As the penetration of variable renewable generation sources such as wind and solar continues to increase, integrating these resources into the power system in a reliable and cost effective manner will become increasingly important. This presentation will describe the major impacts of wind and solar PV on power system operations and planning. Experience to date and studies will be used to demonstrate how these manifest themselves on various systems, both in terms of cost and reliability. Solutions to more effectively integrate variable renewables will be outlined, including technologies such as demand response and storage and new operational and planning techniques. Current R&D in this area will be described, with focus on system flexibility assessment, impact of behind the meter distributed generation, the use of forecasting, and stochastic techniques to optimize power system operations.

About the Speaker

Dr. Aidan Tuohy is a project manager/technical leader at the Electric Power Research Institute, where he has worked since 2010. At EPRI, he is the technical lead for the research program on bulk system integration of variable generation, and innovation scout for Distributed Energy Resource integration. His research interests include power system flexibility assessment methods, the impact of distributed renewables on bulk system planning and operations, assessment of the use of storage and demand response to integrate variable generation, and the integration of variable generation forecasting into operation. He received his Ph.D. from the Electricity Research Centre at University College Dublin, Ireland in 2009, and his B.E. from University College Cork in 2005. Prior to working with EPRI he was a consultant to the International Energy Agency, as well as providing consultancy to various Irish and international power industry companies.
