This paper presents modelling and simulation of an autonomous DC microgrid in Matlab Simulink environment. The proposed microgrid system consists of a wind turbine, solar PV array and DC loads. The wind turbine is interfaced to the microgrid with a rectifier and a buck converter which are controlled to maintain a constant DC bus voltage. While the PV array is connected via a boost converter which extracts maximum power from the circuit. The microgrid system also consists of a centralized Battery Energy Storage System (BESS) which is connected via a bidirectional buck-boost converter. The overall stability of the microgrid is maintained by the control action of the BESS. Finally, simulation study of the microgrid with the proposed control methodologies is carried out for various operating conditions.
