Power Loss Minimization in Smart Transformer Enabled Low Voltage Islanded Meshed Hybrid Microgrid

The smart transformer (ST) offers several features in a hybrid microgrid due to the presence of both ac and dc links while providing various power flow paths. For ST based meshed microgrid, continuous operation is highly important one effective ways achieve it by minimizing line losses. This paper proposes loss minimization strategy which specific for an islanded microgrid. In such system, battery energy storage system (BESS) used maintaining low voltage (LV) bus ST. consists renewable sources, electric vehicles (EV) charging stations, storage, etc. total distribution chosen as objective function optimization problem. active references distributed generation converters charge or discharge schedules EVs are optimally controlled using genetic algorithm satisfying constraints system. Further, LV load shedding also incorporated management. activated on crossing lower critical state BESS. It final measure increase BESS time resulting prolonged Simulation experimental results verify performance proposed scheme. cases considered, compared with conventional management strategies. was observed that particular case, method incurred 1.337 kW losses, able reduce losses 1.0487 kW. shows 22% reduction method.
