This article presents a bi-level optimization structure for concurrently deployment of wind base power production,i.e. Wind Turbine (WT ) with Battery Energy Storage System (BESS) in power distribution networks. An objective function has been devised by considering reverse power flow into main power grid, annual energy loss, node voltage deviation, conversion loss and effective utilization of BESS. Due to huge installation and operational charges of energy storage, the optimal accommodation of multiple WTs and one BESS is simultaneously determined aiming to minimize network power loss. A modified or Corrected Moth Search Optimization (CMSO) has been endorse to solve this problem for a medium benchmark radial distribution network. Considering its unique capabilities of exploration and exploitation for real life problems. Different test cases are investigated to demonstrate the promising abilities of devised framework. The comparison of obtain results from simulation demonstrates that suggested optimization framework significantly reduced the annual energy loss and energy brought from the main power grid, while improving DG hosting capacity of the system.
