The Demand Response Flexibility Forecasting and Optimization (DRFFO) is a module developed in collaboration between ETRA I+D and CERTH. It constitutes a powerful dynamic and integrated tool for real-time building automated monitoring and control, allowing the forecasting of a building’s energy flexibility, based on extracted profiles and current contextual conditions, while further being able to coordinate operation of building’s assets in the optimal comfort and energy efficient manner.

The module’s operation is divided in seven submodules:

• Forecasting calculator: Responsible for the forecasting of the building energy consumption and production.
• Building simulator: Able to perform simulations for every operational state of the building.
• KPI’s calculator: Evaluates all operational states based on specific KPIs.
• Optimal state selection: Based on the KPIs evaluation, the optimal operational state of the building is selected and applied.
• Flexibility calculator: The flexibility (both lower and upper) of the building will be estimated.
• District simulation: Based on the buildings’ simulation, the overall district behaviour simulation is going to be performed by this module.
• Demand response strategies: Manages and coordinates the different demand response strategies among the buildings in the district.
