Resumé

The target for the ENCOURAGE energy management system is to design and test strategies for supply and demand side energy management of a microgrid. This will be done by designing a supervisory controller to manage energy flows so that generated power in the microgrid is mainly consumed by local consumers and the power trade between the microgrid and the grid is shrunk to minimum.
Buildings’ role in providing enough flexibility to the supervisory controller is huge as they account for 41% of total final energy consumption in Europe, followed by transport (32%), industry (24%), and agriculture (2%) (ODYSSEE-MURE project, 2012). When all building loads are considered as critical there would be no opportunity to optimize both the electricity sawing and consumption cost. Optimization of building loads based on electricity price signal includes shedding, shifting or rescheduling the power consumption pattern. To this aim, loads will be characterized by specific flexibility patterns. For instance shiftable loads like HVAC systems will be characterized by the amount of energy that can be shifted in time. This would be, however, at the cost of a wider thermal tolerance that users give permission for. The wider the thermal tolerance is, the more flexibility will be provided to the supervisory controller. Load management strategies will be devised such that thermal comfort and other user-predefined preferences will be satisfied.
A dedicated language was developed to apply the supervisory controller to different houses. This language is used for implementing a glue layer between the load management controller and the middleware lager. Beside this interconnection, between the advanced top level controllers, the dedicated language also handles the curtailable load e.g. the lighting system. Here the main target is not to enhance the flexibility but to lower the energy consumption.
This deliverable reports description of load types, a strategy for energy management at building level, designated supervisory controller for the buildings load management and results of simulation studies.
