The objective of the SuperOPF project is to develop a framework that will provide proper allocation and valuation of resources through true co-optimization across multiple scenarios. Instead of solving a sequence of simpler and approximate sub- problems, the SuperOPF approach combines as much as possible into a single math- ematical programming framework, with a full AC network and simultaneous co- optimization across multiple scenarios with stochastic costs. This effort involves development of the problem formulations, implementation of research grade software codes, and testing of the methods and algorithms on a range of case studies to demonstrate their added value over currently available tools.
