Robust Frequency Reserve Provision through Cooperative Building Energy Management via an Energy Hub


O. Karaca

Semester Thesis, HS15 (10433)

In a power grid, demand and supply of electrical power must be balanced so that the frequency of the grid remains close to its nominal value. The grid operator achieves this stability by procuring so-called frequency reserves, that are dispatched whenever supply does not match demand. Recently, there has been a rising interest in engaging flexible loads such as large office buildings for providing frequency reserves. In this project, we extend the reserve provision problem from individual buildings to an aggregation of cooperative buildings. In particular, we assume that the buildings are cooperatively managed through an energy hub which houses energy efficient components that are shared among the buildings, and defines the interface between the buildings and the electrical grid. For this set up, we present a novel control scheme that determines the optimal size of the reserve capacity by exploiting the variability in energy prices and renewables, while guaranteeing comfort satisfaction of the individual buildings and operation constraints of the energy hub. Moreover, we study the influence of weather uncertainties on the provided reserves. Finally, we quantify the importance of each energy hub component with respect to the reserve size, and also bound the sub-optimality of affine policies that we use to render our problem computationally tractable.
