Optimal Allocation of Energy Storage Systems for Load Management in Distributed Renewable Generations

Abstract

In  recent  years,  the  concept  of  smart  grids  hasbrought  major  development  in  distributed  systems.  Therefore,the  overall  grid  efficiency  can  be  enhanced  with  intended  inte-gration  of  several  different  types  of  renewable  energy  sourcesin   distribution   systems   and   further   target   highest   reliabilityand  reduced  system  losses  with  great  operational  flexibility.  Inthis  paper,  we  address  optimal  allocation  of  storage  devices  forachieving proper and feasible satisfactory load management. Theallocation strategy consists of AC- optimal power flow (AC-OPF)for  suitable  storage  placement  with  the  objective  to  optimizethe   installation   cost,   energy   balance   and   system   losses.   Theproposed methodology is tested for various scenarios of renewableintegrated, IEEE 24-bus standard test network. Hence, the overallsystem  benefits  is  observed  to  be maximized.
