Abstract: The topology of an electric network heavily influences power system operations, power flows, short circuit currents and certain reliability aspects. While meshing increases reliability, it also increases the short circuit power, which can bea problem especially in highly meshed grids. Bus bar switchingis often employed by the system operator for preventive andcorrective actions, as it is a quasi-free control action. Theintroduction of binary variables, representative of the state ofthe circuit breakers, in the optimization description allows for bus bar switching resulting in the adaptation of the topologyof a grid. The goal of this paper is to present an algorithmthat is able to propose a topology that complies with the ShortCircuit Constraints (SCC) whilst respecting the Power FlowConstraints (PFC). Both are adapted in such a way that they allow binary switching actions. The mathematical descriptionof the optimization problem is a Mixed Integer Non Convex Quadratic Constraint Program (MINCQCP) and is implemented in AMPL using the Couenne solver. The paper concludes with two tests that show the functionality of the approach.
