Optimal operation planning of distribution systems considering security constraints

The paper concerns the development of new approaches to the optimal operation planning of radial distribution networks. In particular the model described attempts to configure the medium voltage networks radially for low losses, while meeting constraints on security (reliability), currents and voltages. The model appears to be a very useful tool for planning the normal operating configuration of the distribution system and for reconfiguring radial feeder systems during either emergency or planned outages.
