Generation and demand management improvement with increased variable generation — A Midwest ISO perspective

Abstract

With increased variable generation, the power grid operator faces more challenges in operation. This report presents several methods that the RTO developed to manage the uncertainties through better management of generation and demand. The results of an internal analysis indicate that clear benefits can be achieved through these enhancements. The RTO constantly reviews its operation and makes necessary improvements to add values to society by reliably operating the system in an economic way.Index Terms--security constrained unit commitment (SCUC), security constrained economic dispatch (SCED), rampable capability, wind generation, dispatchable intermittent resources, demand response program.

Participation of Wind Power in LMP-Based Energy Markets

“…The DIR is also similar to NYISO's wind resource management program. MISO observed that the amount of curtailment had increased from 292 674 MWh in 2009 to 594 923 MWh in 2010 [24]. This curtailment was done manually, and MISO proposed that the curtailments be part of the SCED process so that they are managed more efficiently.…”
