Abstract: A paradigm shift has to be realized in future energy systems with high shares of renewable energy sources. The electrical demand has to react to the fluctuating electricity generation of renewables. To this end, flexible electrical loads like electric heating devices and electric vehicles are necessary in combination with optimization approaches. In this paper, we develop a novel privacy-preserving approach for decentralized optimization to exploit load flexibility in residential areas. This approach, which is based on a set of schedules, is referred to as SEPACO-IDA. Compared to the approaches from the literature for decentralized optimization, SEPACO-IDA leads to improvements of between 0.8% and 13.3% regarding the surplus energy and the peak load. Furthermore, this paper illustrates the suboptimal results for uncoordinated decentralized optimization and thus the need for coordination approaches. Another contribution of this paper is the development and evaluation of two methods for distributing a central wind power profile to the local optimization problem of different buildings in a residential area (Equal Distribution and Score-Rank-Proportional Distribution). These wind profile assignment methods are combined with different decentralized optimization approaches. The results reveal the dependency of the best wind profile assignment method on the used decentralized optimization approach.
