The increasing penetration of fluctuating renewable energy sources (RES) in the power grid increases the need for ancillary services (AS), i.e. frequency reserves and voltage regulation. Traditionally, AS come from conventional power plants. If properly aggregated and controlled, however, loads can also offer AS. Possible advantages are lower cost and higher quality, sometimes even combined with a reduced environmental footprint. In this paper, we address AS provision with an aggregation of large office buildings. We investigate upper bounds on the amount of frequency reserves that can be extracted using a hierarchical control structure. Based on simulation results, we discuss the technical and economic potentials of office buildings when they participate in the Swiss frequency reserve market. Moreover, we point out challenges and open questions that are currently under investigation.
