Distributed Frequency Reserve Provision of an Aggregation of Buildings

Master Thesis, SS16 (10527)

In order to maintain a constant frequency in a power grid, the amount of energy produced and consumed must be balanced at all times. One option to achieve this balance is by adjusting the power intake of large electricity consumers. The idea is that these consumers, e.g., office or residential buildings, offer a ’frequency reserve’ in the form of controllable power consumption. The grid operator can then request these reserves when needed. This work centers around the optimization-based decision by consumers on how much frequency reserve can be provided. In particular, we investigate the case where many consumers, e.g., an aggregation of buildings, collaborate to provide reserves together. We place a special focus on how to solve the resulting large-scale optimization programs in a distributed fashion, using the alternating direction method of multipliers (ADMM). We show that for the reserve provision problem the ADMM procedure has very beneficial properties, such as good scalability with the number of participating buildings and retaining feasibility. We also investigate how technical quantities from within the ADMM iteration, guaranteed feasibility, can be used to distribute the financial profit from reserve provision among the participants in the provision problem.
