In this paper, optimized controller design for multiple distributed generators (DGs) based microgrid network is discussed, where IEEE 1547 standards are followed for primary photovoltaic DG. According to standards, the primary photovoltaic/auxiliary battery energy storage system is integrated through voltage source converter's feedback controller, with operational modes: active reactive (P − Q) power control for grid synchronized operation and voltage frequency (V-f) droop control for islanded microgrid. To overcome the inadequacy of conventional controller tuning in a multiple DGs-based weak microgrid architecture, a new mutation based improved firefly algorithm is proposed in this paper. The worst stability operation is considered for voltage source converter's P-Q and V-f coordination during insufficiency in battery energy storage system management. The effectiveness of the proposed technique is validated on MATLAB Editor/ Simulink platform. Further, a hardware-in-loop test bench validation is achieved by TMS320 C6713 based DSP Starter Kit and embedded MATLAB coder.
