NERC/NAGF/ESIG Battery Storage, Hybrid Resources, Frequency Response and Grid Services Workshop

Battery Storage, Hybrid Resources, Frequency Response and Grid Services Workshop Agenda

Orientation, Welcome and Overview (Allen Schriver/NAGF, Mark Ahlstrom/ESIG)

Opening Keynote: Storage and other drivers of grid transformation
Elizabeth Salerno, Technical Advisor to FERC Commissioner Glick

Panel 1: Technical capabilities of battery energy storage systems 

― Battery and inverter technologies
― Services storage can provide (energy, peak shaving, PFR, FFR, regulation, etc.)
― Reactive capabilities of battery energy storage systems (including while charging)
― Economics of provision (efficiency, degradation, implications on PPAs and offers)
― Batteries in hybrid systems – DC-coupled versus AC-coupled, does it affect the above?

Energy Storage Overview and Market Drivers, Jeff Plew, NextEra Energy
Storage in Hybrid Systems, Chris Larsen, Dynapower
Unlocking the transition to a low-carbon, reliable electrical system with hybrid storage solutions, Arvind Tiwari & Jason MacDowell, GE

Panel 2: Hybrid projects: motivations, drivers and challenges

― Driving factors behind hybrid projects – in regulated and market regions
― DC-coupled versus AC-coupled – drivers and implications for integrating into existing power systems (e.g., visibility, controllability, forecasting, dispatch, evaluation)
― Arguments for a hybrid resource model and treatment as a unified resource type
― Hybrids versus renewables – differences in approaches for offering ancillary services
― Implications for hybrid capabilities, offers and higher-level grid services

Unlocking Solar’s Full Potential, Mahesh Morjaria, First Solar
Defining and Solving For Grid Needs, Ray Hohenstein, Fluence
Hybrid Resources as Power Plants: Simplifying Markets and Grid Operations, Mark Ahlstrom, ESIG/NextEra Energy

Panel 3: Planning, interconnection and modeling with storage and hybrids

― Modeling – DC/AC coupling, charging as negative gen vs load, etc.
― Communications, controls and protection
― Interconnection requirements/expected performance of storage when charging
― Interconnection studies for “service less than nameplate” interconnections
― BES-connected storage and hybrid resources
― Distribution-connected storage, hybrids, aggregated DERs and load patterns
