Unstructured Testing Tips 6 Types of Items MPs Should Test: DA Market Self commit during an operating day Self commit resources in the DA Market based on the MPs EIS resource plan (especially when settlements is available to see the interaction between DA Market and Real Time) Vary startup & no load costs on a resource to see the impact on clearing Vary resource prices to see impact on clearing Vary offer curve prices and slope to see impact on clearing Submit price sensitive demand bids commensurate with unit offer prices and overall P&L Submit virtual bids/offers at different pnodes, utilizing tiered offers Vary different commitment parameters and analyze results Max Daily Energy, Max Daily Starts, etc. Change Offers for Reserve Products Price Status Alan Adams

Unstructured Testing Tips 7 Types of Items MPs Should Test: RUC Vary different commitment parameters and analyze results Max Daily Energy, Max Daily Starts, Etc Change Commitment Status Reliability, Market, Outage, Self RT Market Change resource offers for limits, ramp rates during the day to observe the effects on defects Try various offers that include fixed and market offers Vary reserve offers and ramp rates on different resources to see the effects on clearing Observe behavior of units when submitting different unit status’ between the markets (ex: DA Market = Self, RT Market = Market) Alan Adams

Unstructured Testing Tips 8 Types of Items MPs Should Test: RTGEN Integration with RTGEN startup and shutdown sequence – managing control mode 1. Control mode of 0 when offline 2. Control mode of 3 when ramping to min 3. Control mode of 1 or 2 when on and dispatchable 4.

Unstructured Testing Tips 9 Types of Items MPs Should Test: Once CROW is integrated: Try to submit offers in the DA Market for resources that are outaged Once RTOSS is integrated: Enter in Dispatchable/Up to TUC transactions with very low prices to verify they clear if they are in the money Enter in Dispatchable/Up to TUC transactions with very high prices to verify they do not clear if they are out of the money Settlements: All kinds of changes and options Virtual bids vs. price –sensitive demand bid, URD, trigger other charge types Unstructured Testing Tips Unstructured Testing Tips posted on spp.org  spp.org > Integrated Marketplace > Market Trials > Structured/Unstructured Test > Integrated Marketplace Market Trials Project Documentation Folder Alan Adams
