Test Specification TC7.TS02
Test Rationale
The test is to evaluate the performance of the decision-making process in the Bidding module, which outputs are final energy, price bids, and the control signals for the controllable electrical devices.

Test Design
The test considers several consecutive load and generation variations based on the forecasted modules, as wells as price bidding variations. These are needed to adequately evaluate the capability of the operation and bidding modules to cope with these conditions.
Initial system state
- Measurement of input parameters to perform a perfect forecast of RES and demand
- Measurement of electrical parameters
- The imbalance should be under 5%.
- Optimal setpoints to the devices
Evolution of system state and test signals
- Technical constraints (e.g., voltage level, losses, loading, unbalance) are verified as a result of the continuous connection of several controllable electrical devices.
- Correction of the prosumers’ bids based on their power consumption and generation forecast, as well as the fitting parameters of their devices’ models
Other parameters
N/A
Temporal resolution
From several minutes to an hour
Source of uncertainty
Environmental conditions, consumers’ demand, EVs arrivals, the accuracy of measured signals, communication delay, RES and demand forecasting
Suspension criteria / Stopping criteria
Violation of the technical operating levels of the grid, i.e., voltage, losses, and thermal capacity A significant price deviation due to loss of communication
