Abstract :
Different control strategies to achieve the maximum output power from DC-DC boost converter with variable solar PV generation are presented in this paper. In order to ensure the stability of a DC microgrid, the power flow within the DC microgrid must be balanced at all times to maintain a constant dc bus voltage. A comparison between Perturb and observe (P&O), incremental conductance (INC), PID open & closed loop and dynamic evaluation control (DEC) techniques are discussed in this paper. MATLAB/SIMULINK simulation results are presented to demonstrate the comparison between control strategies.
