Abstract

In this research work economic operation of power system and its incremental cost management has been maintained through identical distributed generation. At first, configuration of Hybrid (Alternating current/direct current) AC/DC Micro grid (MG)DC sub-grid (SG) is designed and then a droop control method based on incremental cost is implemented for synchronization of sub-grid’s DC bus voltage & AC bus frequency to equalize incremental cost. However, droop method causes deviations in dc bus voltages and AC bus fervency. Secondly, distributed fuzzy logic control architecture with incremental cost-based droops is proposed and implemented which allows uncertainly distributed generations communicate with their neighbor ones thus reducing communication weights and enhances the uncertain system performance. Due to existence of fuzzy logic controller in proposed architecture the transient behavior of the system voltage and frequency is reduced and reaches to steady state in minimal time. Moreover, the incremental cost of all distributed generations is equalized.  To show the efficiency of planned control strategy using a platform called MATLAB/Simulink to verify results.
