The framework is applied to IEEE 33-bus and 69-bus standard test systems. The framework uses the advanced grey-wolf optimization (AGWO) developed to deal with mixed-integer nonlinear programming problems and the forward-backward sweep power flow method to determine the optimal control parameters defined for the problem. This study shows that the proposed framework enables the allocation and operation of DG and MBESS units to eliminate all voltage violations. Moreover, a clear roadmap is proposed for the size and location of DG units in the system and guidelines for the monthly location of MBESS. © 2023 IEEE.eninfo:eu-repo/semantics/closedAccessDG PenetrationMobile Battery Energy Storage SystemOptimizationSeasonal Battery AllocationVoltage ViolationsConference Object36837310.1109/EI259745.2023.105126762-s2.0-85194142119N/AN/A
