Dear Matpower Community, I try to work on a network topology optimization problem where only transmission switches are the only binary variables. The objective is to conduct short-term (up to 5 hours ahead) network reconfiguration to reduce the 'congestion cost' while maintaining the N-1 contingency.
I plan to develop my own algorithm to tackle the problem, using an evolutionary algorithm that would allow me to keep the AC power flow equations in the optimization. 'Congestion cost' can be quantified using shadow price, but my understanding is that shadow price can only be calculated by the dual problem of DC OPF, so maybe I can just use the device loading to represent the congestion cost in the objective function? My question is: 1. Anyone can share insights on what test system is best for this type of problem? 2. Any inputs on this problem or how would you start? Best, Wenlei
