Preliminary Program

13:00 – 14:00


14:00 – 15:00

Lecture 1 (45 min.)
Lessons Learned from Grid Integration of VRE: Resource Adequacy and System Balancing
Debra Lew (Debra Lew LLC, USA)

Variable renewable energy resources create challenges for utilities to meet resource adequacy requirements because VRE may not be coincident with system peak demand and VRE output during system peak periods varies inter-annually. We discuss how methods for determining resource adequacy may need to be modified to consider high penetrations of VRE. High penetrations of VRE can contribute significant variability and uncertainty to the system operators’ responsibility of balancing the system. In this lecture, we cover many mitigation options for system balancing and considerations that each utility must undertake to determine what makes the most sense for their system.

Discussion (15 min)

15:00 – 16:00

Lecture 2 (45 min.)
Lessons Learned from Grid Integration of VRE:  Frequency Control and System Stability

Nicholas Miller (HickoryLedge, USA)

The dynamic performance of interconnected power systems, especially the transient response to grid disturbances, is substantially changed by the substitution of inverter-based variable renewable resources (IBVRE) for traditional synchronous generation. Ability to maintain frequency control following loss of major generation units or interconnectors is strongly influenced by reduced synchronous inertia and rapidly responding IBVRE. Transient stability, particularly first swing stability between importing and exporting systems can be radically altered by IBVRE. This lecture will explore lessons learned in large-scale integration studies, including opportunities to improve utilization of transmission infrastructure beyond levels possible today with predominantly synchronous generation.

Discussion (15 min)

16:00 – 16:30

Coffee Break

16:30 – 17:30

Lecture 3 (45 min.)
Lessons learned from Grid Integration of VRE in Ireland and Northern Ireland
Achieving the highest levels of wind integration. It’s what you think that is true that ain’t that holds you back!
Jonathan O’Sullivan (EirGrid, Ireland)

Ireland and Northern Ireland have integrated over 30% annual of electricity consumption already. They are planning on meeting almost 70% wind integration annually by 2030.

The presentation will highlight some of the key areas completed and being proposed that are seen as critical to its success. However these issues are against the foundations of every market and power system conventional operations.

Discussion (15 min)

17:30 – 18:30

Lecture 4 (45 min.)
Lessons learned from Grid Integration of VRE: Activities in 20 Countries
Thomas Ackermann (Energynautics, Germany)

Thomas Ackermann will share his experiences of 25 years of world-wide work in the area of grid integration of renewables and electric vehicles. The presentation will give an overview of challenges and lessons learned.

Discussion (15 min)
