Talk Title: "Treating Uncertainty in Electricity Markets by Defining Ramp Capability Products"
Series: Epstein Institute Seminar Series
Abstract: Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) use Security Constrained Unit Commitment (SCUC) and Security Constrained Economic Dispatch (SCED) models to operate their electricity markets and power systems. In the Real-Time market, the ISO typically forecasts the system requirements (e.g. five minute loads, operating reserve requirements) and system capability (e.g. a generatorâs maximum output available and ramp rate, transmission constraints) for upcoming dispatch intervals over a dispatch horizon. It uses SCUC and SCED to find a least-cost commitment and dispatch that satisfies the power balance, transmission flow limits, and resource limits in each dispatch interval over the planning horizon.
SCUC and SCED do not account for uncertainties in forecasts of load or resource capability. They will dispatch the system to achieve least cost over the dispatch horizon for a single forecast. As a result, the dispatch may not maintain any flexibility for the RTO to adjust the dispatch to respond to changes in forecasts as time progresses over the dispatch horizon. This can result in transmission violations or shortages of energy or reserves when forecasts change along with price spikes. To avoid this, the RTO will need controllable resources for which the RTO can alter power output to meet varying needs. With increases in the proportion of generation from intermittent renewable resources and increases in the flexibility of interchange scheduling (e.g., 15 minute scheduling intervals), it is likely that the variability the RTO will face will increase in the future, taxing the ramp response of controllable resources and increasing the frequency of short-term scarcity events due to shortages of rampable capacity.

Biography: Paul Gribik joined PG&E in 2012 where he works on market design and analysis issues. Prior to that, he was at Midwest Independent Transmission System Operator where he was a Senior Director. He joined MISO in 2003 as Director of Financial Transmission Rights. He developed the processes that were used to allocate FTRs to market participants and organized the group that runs the MISOâs FTR markets. He later started the Market Development and Analysis Group at MISO and led the group in developing a variety of market processes and in analyzing market outcomes. Most recently, he led their efforts to develop the Extended LMP methodology that allows commitment related costs to be included in LMPs, ramping flexibility products, and a zonal reserve procurement methodology that incorporates transmission constraints.
Prior to joining MISO, Paul was a consultant from 1989 to 2003. He worked on developing electricity markets and on evaluating market processes and software. He also assisted electric utilities and independent power producers with their planning and operations problems both in areas with RTOs and without RTOs.
Paul received a BS in Electrical Engineering, a MS in Industrial Administration and a PhD in Operations Research from Carnegie-Mellon University.
