Advanced DMS to manage active distribution networks

The paper presents an advanced distribution management system capable to manage an active distribution network economically and safely. The DMS optimizes the power flows in the network, regulates the voltage profiles, acting on reactive flows and tap changers in substation, minimizes the energy losses, reconfigures the network, exploits storage devices and responsive loads in an integrated way. The optimization algorithm finds the optimal combination of such operation options to minimize system costs without causing violations of the technical constraints. The system costs include the energy losses, the cost of generation curtailment, the cost of reactive power, the cost of load shedding, and the cost of storages. The proposed method has been applied on a model test network to verify the validity of the approach.
