The future smart grid will connect the different stakeholders and participants, generating and consuming units alike, not only by the power distribution grid itself but also via communication and information networks. Through these communication links not only measurement data (Remote Metering) should be exchanged but also information like tariffs or about the grid status are thinkable. Especially possibilities for balancing the mismatches between the amount of generated energy and demanded energy are looked upon.
The recent years brought an increased interest in the research field of demand response and the structure and elements of the smart power grid. One target is to include the demand side of the power infrastructure into the dynamic process of adjusting imbalances in situations of too low or too high generation of electrical energy. In difference to former approaches not only altering the generation side of the power equation but also the demand side introduces new flexibilities into the process. Influencing the load (or generation) profile of the different nodes lead to scenarios where each and every participant is an active element inside the large power infrastructure.
Especially "new" elements like small-scaled generation units (Wind, Sun) or storage units of different kinds have very special demands on the smart power grid because of their geographical distribution and their limited flexibilities. On the other hand could the stronger integration of renewables bring a stronger decentralization of the generation units and therefore a lower dependence from single generation units.

To use the potential of active and communicating nodes in the power grid new and innovative control algorithms have to take care that all different participants of the power grid – loads, storages and generation units - are used in an optimal way. On the power grid’s side a functional unit is needed that can monitor and interpret the current status of the power grid and on the hand is able to communicate with the different units of all different kinds (load, generation, storage) and influence their actual contribution to the grid status. This unit is often called a "Smart Grid Controller". One of the main problems with this Smart Grid Controller is, that there does not exist a universal specification of its requirements and features.
The integration of the demand side for voltage and frequency control purposes in the electric power grid is one of the essential features that should be made possible by a Smart Grid Controller. The project Building to Grid analyzes the behavior and potential of buildings in such a setting in which the Smart Grid Controller represents the smart grid and influences the load behavior of the connected buildings. For Building to Grid, a controller with limited capabilities will be used, which provides a web interface used to input load control commands.
This master thesis deals with the design and implementation of this Smart Grid Controller. First of all, a suitable protocol for the controller to building communication must be found and subsequently implemented. Furthermore, the controller application and web interface have to be developed.
