Circulating Current Minimization and load sharing control of the DC Microgrid based on Optimal Droop parameters
The DC microgrids are getting popular as an effective means to integrate various renewable energy sources. The droop control is effectively utilized in order to minimize circulating current among sources of microgrid. The unbalanced cable line impedance is the main cause to enhance circulating current. In this paper, the circulating current among source converter is minimized based on optimal droop parameters. The trade-off between effective load sharing and bus voltage regulation of DC micro grid is mitigated for a range of loading condition of unequal cable line parameters. The optimal droop parameters are calculated based on Grey Wolf Optimization (GWO) technique of the system. The performance analysis of the microgrid is verified by real-time simulator in the dSPACE 1202 platform.
