Hybrid energy management system for microgrid applications

The paper presents the application of DSP processor for energy management system (EMS) of non-renewable energy and renewable energy sources intended for grid connected applications. The hybrid supplies like wind power, solar power, fuel cell is the clean energy source with zero emission of hazardous gas. It is used in the portable power generation, stationary power generation and power for transportation. The storage devices like battery or ultra-capacitor is connected parallel to store the energy and to improve the transient response. The combination of hybrid energy and storage devices are considered for better charging and discharging with better life time of the battery and ultra-capacitor. The presented scheme explain the generation of pulse width modulation (PWM) gated pulse signals using the TMS320F28335 DSP digital signal controller with MATLAB/Simulink and Code composer studio (CCS). The plant for hybrid energy and storage devices based energy generation is intended for grid connected applications implemented in the dSPACE 1104 R&D Controller board for real time simulation and output of the system.
