Smart Demand Response Management of Islanded Microgrid using Voltage-Current Droop Mechanism

The reduction of power of the autonomous microgrid is proposed in this paper. The concept utilized is Conservative Voltage Reduction (CVR). The active and reactive power consumption of the microgrid decreases and a power reserve of the system increased. The voltage-current droop mechanism is used to lessen the voltage of the DG and it reduces the consumption of power on the consumer side. This reduced power is used to cater more demands. The control strategy is used to cater the greater number of loads at the time of power shortage. The DG taken in this paper is photovoltaic (PV) system and perturb & observe MPPT is used. The interleaved boost converter is used as DC-DC converter as it lessens the ripple of the output voltage and inputs current. The simulation is done on MATLAB platform and results are validated at different loading conditions and comparison has been done with P-f/Q-V mechanism.
