WIRAB webinar on Primary Frequency Response

The Western Interconnection Regional Advisory Body (WIRAB) hosted a one-hour webinar – led by Debra Lew and Nick Miller of GE Energy – on primary frequency response (PFR) of generators within the Western Electricity Coordinating Council (WECC) region.

The key concern with PFR is that currently variable energy resources (VERs), specifically wind and photovoltaics (PVs), are not required to provide PFR. PFR is critical to maintain reliability of the interconnection in the event of a contingency. Wind and PV are the fasting growing resources, and with increasing Renewable Portfolio Standards (RPS) requirements in many states this will lead to continued growth. Because wind and PV have very low marginal cost, they tend to displace other generation that may have been providing PFR.

The webinar covered how different types of generators provide PFR, lessons learned from previous studies of VER penetration and PFR, and generator control settings. GE Energy delivered a draft report on PFR to WIRAB members on April 4, 2016. The webinar addressed the information and findings provided in the report.
