Solar Forecast Tools, Primary Frequency Response Topped OC Agenda

The importance of reliability to PJM and its stakeholders was threaded throughout the Operating Committee meeting on April 11, as a look at solar forecast tools and primary frequency response requirements preceded an overview of the recently published resource mix report.

Mike Bryson, vice president – Operations, reviewed the report, Evolving Resource Mix and System Reliability, and briefly discussed the related Grid 20/20 forum on April 19.

Bryson reiterated that the purpose of the report was to examine reliability impacts of the evolving fuel mix while purposefully avoiding environmental and policy issues. Bryson discussed many of the study assumptions with stakeholders and welcomes the conversation that the paper has generated.

PJM presented the information on solar forecasting as part of an update of Manual 14D: Generator Operational Requirements. The Federal Energy Regulatory Commission Order 764 requires PJM to develop tariff revisions to include additional data reporting requirements for solar power resources.

The solar forecasting includes weather data PJM can share with members for their use – generation owners for offering and scheduling and transmission owners to assist with outage coordination. PJM is working with stakeholders to benchmark accuracy and develop the new data requirements for both Manual 14D and the Tariff.

The stakeholders reviewed a PJM-proposed problem statement and issue charge related to generator primary frequency response requirements. Primary frequency response is an essential reliability product and is needed to ensure system reliability and stability in both real-time operations and during system restoration events.

The FERC issued a Notice of Proposed Rulemaking in November of 2016 on primary frequency response. It requires all new small and large generators to install and enable primary frequency response capability. The rule applies to synchronous and non-synchronous resources.

PJM provided an update on the joint stakeholder initiative between PJM and NYISO to address issues related to the Ramapo phase angle regulators.

Stakeholders also reviewed plans related to the next PJM-wide Black Start request for proposal (RFP) process. The PJM target for issuing the next five-year grid-wide process is January of 2018; it will target new black start units that will be available in 2020. PJM will schedule a one-hour review and feedback session after the May OC meeting to review lessons learned and solicit feedback on methodology and potential new requirements.
