Loss Minimization in Medium Voltage Distribution Grids by Optimal Management of Energy Storage Devices

This paper presents an algorithm for optimal operating of energy storage devices in medium voltage distribution grids. Losses minimization in such grids has always been of paramount importance for power system planners and, in literature, a number of approaches were proposed. In this paper a novel method for losses minimization of power distribution grids by means of genetic algorithm is presented. This method is based on the definition of optimal management strategy of energy storage devices. The optimal placement of the storage device was assessed by comparing the losses reduction when the storage device was installed at different busbars. The efficiency of the proposed algorithm was studied through simulations of several case studies on a CIGRÉ medium voltage test grid
