Subject: [OASIS Issue Tracker] (ENERGYINTEROP-702) Representing Inflexibility

     [ https://issues.oasis-open.org/browse/ENERGYINTEROP-702?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

William Cox updated ENERGYINTEROP-702:
    Fix Version/s: ctsWD17
WD17 Sections 8.4 and 9.4 describe use of supply/demand curves in CTS. The extensible Resource Designator enumeration offers additional resource hence products.

Different market clearing methods are exposed through Market Characteristics - see Section 8.4.

> Transactive energy systems should be able to represent both their flexibility and inflexibility. Failure to do so will create exceptions and will rely on assumptionsâlike the existence of a predetermined market position or baseline. Consider, for example, a transactive system design that must communicate not only its available flexibility, but also its existing baseline apart from such flexibility. Regrettably, the number of objects having no flexibility is typically much greater than the number offering flexibility. Also consider the growth of renewable energy resources, which contribute virtually no flexibility to be controlled by prices but are becoming an important component of global electricity supply.
> Figure 2 demonstrates alternative representations of inflexible supply and demand. Unlike the binary flexibility discussed in Section 1, inflexible supply or demand possess no meaningful strike price. Inflexibility implies that the quantity would be the same regardless of price. One way to extend CTS to represent inflexibility would be to populate the strike price with a value (e.g., â or NULL) that would clearly indicate inflexibility. If this number or symbol is used consistently, it 
> would be easy to identify and aggregate inflexible supply and demand
