Towards multiobjective optimization and control of smart grids

The rapid uptake of renewable energy sources in the electricity grid leads to a demand in load shaping and flexibility. Energy storage devices such as batteries are a key element to provide solutions to these tasks. However, typically, a trade-off between the performance-related goal of load shaping and the objective of having flexibility in store for auxiliary services, which is, for example, linked to robustness and resilience of the grid, can be observed. We propose to make use of the concept of Pareto optimality in order to resolve this issue in a multiobjective framework. In particular, we analyze the Pareto frontier and quantify the trade-off between the nonaligned objectives to properly balance them.
