Assessing the capability of Swiss office buildings to provide secondary frequency reserves


D. Geiter

Semester Thesis, SS17

It has been shown that large buildings with high inertia are capable of providing ancillary services. But the full potential of such buildings has not yet been exploited. The importance of finding new ways to provide ancillary services only increases with the high amount of renewable resources nowadays. Unpredictable energy generation as well as energy consumption requires frequency reserves to keep the grid frequency at its nominal value. The goal of this work is to investigate on the energy storing capabilities and thermal inertia of such large buildings and estimate their abilities to provide secondary frequency reserves.
To understand the thermal behaviour of a building and its states, we perform excitation setups of different lengths to determine thermal inertia and the efficiency at storing energy. The setups include different waiting times after excitation and zero-mean excitation to assess the energy efficiency. As a guideline for the excitation times we determine the main frequencies of a demand-response signal.
Since we are interested in the building providing secondary frequency reserves, such an experiment is performed in the last section. We simulate a realistic setting with the application of a demand-response signal and study the impact on the comfort constraints inside the building. Furthermore, a focal point in this work is the comparison of different building and construction types such as high and low weight construction.
