Abstract
A single-phase AC-DC Hybrid Micro-Grid (HMG) power flow control strategy is modeled and simulated in this paper. Two AC and two DC zones are separated by a bidirectional interlinking converter (BIC) in the full bridge IGBT structure, which is a typical H-Bridge inverter/rectifier, in the proposed HMG system topology. Based on the DQ transformation theory, the BIC's switching pattern comes from one voltage loop (Vdc) and two power control loops. The transfer of both active and reactive power between the HMG and the public AC Grid is controlled by this control strategy. Additionally, this can be accomplished in either rectifying or inverting modes by utilizing the bidirectional converter. Matlab-Simulink is used to implement and test the simulation model.
