BEopt Demand Response and Stochastic Schedules between versions
Versions 2.2 - 2.8 had demand response options. In version 3.0.1 it no longer shows 'demand response', but 'stochastic' is now a schedule option for: plug loads, hot water fixtures, clothes W/D, dishwasher, cooking range, lighting. Can anyone give more information or documentation on the Stochastic schedule option in the latest version of BEopt?
We found this 2022 Building Energy Modeling Enhancements report: "Stochastic modeling of loads is also necessary to rigorously quantify load flexibility and demand response potential (Mims Frick et al. 2019). As of 2018, NREL residential modeling used pre-generated stochastic event schedules for hot water draws, clothes washer power draw, and dishwasher power draw, as well as bathroom, kitchen, and clothes dryer exhaust ventilation. This is because event schedules can be important for modeling the effect of clustered draw events on heat pump water heaters and for modeling the interaction between exhaust ventilation events and natural air infiltration. However, we concluded that there was great potential and need to apply stochastic load modeling more comprehensively in the EnergyPlus/OpenStudio residential modeling platform across many other residential end-use categories."
