Abstract
For synthesis of distributed energy supply systems, the complexity of the mathematical optimization problem is commonly reduced by time-series aggregation. Today, the accuracy of the aggregation is measured in the time-series domain, i.e., by the capability of the aggregated time-series to represent the original time-series. In this paper, we propose a method for time-series aggregation measuring the accuracy of the aggregation in the domain of the objective function: The error is evaluated between the operational expenditure resulting from calculations using the aggregated time-series and the original time-series. An adaptive procedure selects representative time-steps for the aggregated time-series. It is shown that aggregation to few time-steps is sufficient to represent the original time-series with excellent accuracy in operational expenditure. © 2016 Elsevier B.V. Show more
