This variable defines the hpy_emonth end month for the constraint. Also applies to demand response units. (Month) Peaking units with hours per year (thermalhpy) operating constraints can narrow down the period of available operation. This variable defines the hpy_smonth start month for the constraint. Also applies to demand response units. (Month) Indicates the load responsive demand curve for a specific demand Load_responsive_demand_id response resource. This is used for modeling price responsive resources that provide more or less output during higher load periods. The default setting for the random draws using the Load_responsive_demand_random load_responsive_demand curve is performed on a daily basis. To perform these draws hourly, the load_responsive_demand_random should be Y. Represents the maximum number of times the Demand Response resource can be called in a single day. Differs from hours because the Max_dispatch_per_day resource can be called for consecutive hours, which is counted as only one dispatch.
