Renewable bid allocation - no FCAS
Summary
The allocation logic aims to maximise value in a similar way to how Traders intuitive and dynamically bid renewable plant. That is, Traders price volume depending on the expected price and the expected price trajectory for every dispatch interval.
Importantly Traders use their skill to set key parameters in pdBidr. These are four priceband values and two trader parameters called Trader Price Max (TPmax) and Trader Price Min (TPmin). The Trader Parameters, SRMC (or turn down value) and forecast prices determine which pricebands volume will be allocated. along with determine
pdBidr allocates all volume to one of the following pricebands based on
Inputs
Information | Source | Description |
|---|---|---|
SRMC+ | Solver (any upstream process would do however the solver already calculates this liability). If FCAS liability is excluded then the source is the Trader Parameters. | This is intended to represent the static SRMC plus the Raise Contingency FCAS liability (which is usually very small). Note that the addition of the FCAS liability can be disabled if required. If it is disabled then this constant can be thought of as TraderPriceMiddle, much like TPmin and TPmax |
FRRP | User selected price forecast source | The forecast energy price |
TraderPriceMinimum and TraderPriceMaximum (TPmin and TPmax) | Trader parameters | The upper and lower pricebands that are meant to span the flat area of the supply curve that represents the bulk of the SRMC of the regions renewable plant. |
Constraint_status | MMS.dispatch_local_price | Constraint_status is equal to 1 if local_price_adjustment is positive and represents the unit is at risk of being constrained OFF, 0 means there are no binding constraints for that unit and -1 means that the local_price_adjustment is negative and represents the unit is at risk of being constrained ON. As of the time of writing we consider it best to enter the constraint_status as a static trader parameter. |
max_capacity (MC) | MMS.dudetail | The volume to allocate in the chosen priceband. |
