  4. Abstract:
  5. In future smart grids, energy storage systems (EESs) are expected to play an indispensable role in balancing continuous load changes arising from customers' life-style as well as varying output of intermittent energy resources. This, however, needs significant investment that should be justified prior to their implementation. This paper presents a model to find the optimal capacity for ESSs in distribution systems. The model aims at maximizing system owner profit by reducing total electricity procurement costs. The model is formulated as a mixed integer non-linear programming problem. Due to the complexity and large size of the problem, a decouplebased method is proposed wherein optimal charge/discharge pattern of ESSs is obtained via a quadratic programming (QP) model. The method is applied to the IEEE 33-bus network and simulation results are thoroughly discussed. © 2015 IEEE
