This chapter focuses on the analysis and assessment of multiple technical benefits of BESS in improving daily network operations of distribution systems. While this kind of analysis needs to be based on modelling and simulation of distribution networks including BESS, the time-series power flow (TSPF) simulations are also required at first in the development of dispatch schedule for BESS and at later stages to assess the efficacy of the scheduling algorithm over longer periods including different case scenarios. Moving up from requirements of modelling to multi-objective optimization.
