Abstract :
The main goal of active distribution network operation is the minimization of system cost given by the sum of the costs of energy losses, curtailed energy, reactive support, shed energy, and storage operation. The paper focuses on the use of Distributed Energy Storage, showing that suitable OPF algorithms embedded in the Distribution Management System increase the hosting capacity of distribution system without jeopardizing reliability and minimizing the operation costs. Costs and benefits of energy storage are compared with other no-network solutions and the impact on the efficiency of power delivery is deeply discussed with reference to a small real world case study.
