Modeling GEB appliances

[joseph-robertson]

To be able to model load shifting of appliances.

Approach 1

Add the following arguments to the BuildResidentialScheduleFile measure:

• [ ] schedules_peak_period (optional; str). Must be between 1 and 12 hours. Default '15 - 18'.
• [ ] schedules_peak_period_delay (optional; int). Default 0.
• [ ] schedules_peak_period_xxx (optional; bool). Default false. Choices for xxx are: cooking_range, dishwasher, clothes_washer, clothes_dryer. Others?

Based on the previous inputs, stochastic schedule values falling within the peak window are shifted to after (offset by delay) the end of the peak window.

Other details/questions:

• If shift would cause any stacking of events, do not shift (shouldn't happen often).
• Applies to appliances consuming any fuel type.
• Should we support defining a different delay value for each appliance?

Approach 2

Perhaps we follow the approach for vacancy and power outage periods. For example, create a new schedules_peak_period argument in BuildResidentialHPXML (along with weekday/weekend and delay arguments?) that populate the HPXML like so:

      <PeakPeriods>
        <PeakPeriod>
          <BeginHour>15</BeginHour>
          <EndHour>18</EndHour>
          <Weekdays>true</Weekdays>
          <Weekends>false</Weekends>
          <Delays>
            <Dishwasher>0</Dishwasher>
            <ClothesWasher>2</ClothesWasher>
          </Delays>
        </PeakPeriod>
      </PeakPeriods>

Then we could support (1) multiple peak periods per day, (2) application to all schedule types (not just stochastically generated), and (3) defining a different delay value for each appliance.

Suggestions/thoughts:

• Begin/end dates for supporting different parts of the year
• Approach 2 > 1 in terms of supporting smooth schedules
• Does this fall outside the realm of OS-HPXML?
  • Should it be a separate "GEB" measure that occurs after (downstream of) OS-HPXML measures (think "comfort model" for power outages)?
  • Vacancy and power outage might have tighter connection to OS-HPXML, and so should be integrated
  • BCL integration
  • Investigate current capabilities/measures on BCL
  • Talk to David for more info around repos, testing, etc.
