Bottom-up optimization models neglect the inclusion of investment behavior We introduce three investor types that … differ in their investment cost specifications, financing costs, and discounting. This leads to a substantially different … accounting for more differentiated picture of electricity market investment with heterogeneous investor types can provide a …

Adjustable Robust Optimization (ARO) yields, in general, better worst-case solutions than static Robust Optimization (RO). However, ARO is computationally more difficult than RO. In this paper, we derive conditions under which the worst-case objective values of ARO and RO problems are equal. We...
