Here, a new energy management strategy based on a multi-agent structure is presented by introducing hybrid control of AC micro-grid (MG), where current harmonics compensation is also considered. This energy management strategy is based on Mealy machine in a multi-agent system (MAS), which is implemented by generating coordination signals and sending them to the renewable energy sources (RES). In RES, maximum power point tracking (MPPT) or reverse of Hill-climbing (RHC) is used based on these received coordination signals to limit the exchange power between the MG and the grid. Also, the multi-agent structure of shunt active power filters (SAPFs) and passive filters have been studied in power MGs. The comparison of MG current harmonic compensation by these filters by fast Fourier transform (FFT) algorithm has been investigated in the proposed network. The simulation results show that the proposed energy management system (EMS) with proper management of MG different agents has been able to have a suitable performance for hybrid distributed generation (DG) systems. Also, the SAPF with better and more appropriate harmonic compensation than the SC-RC-LCL passive filter can eliminate the harmonic pollution of MG and be used with high performance in hybrid DG systems.
