The paper presents the modelling and simulation of the power flow control strategy of a single-phase AC-DC Hybrid Micro-Grid (HMG). The proposed system topology for HMG contains two AC and DC zones delimitated by a bidirectional interlinking converter (BIC) in a full-bridge IGBT structure which is a regular H-Bridge inverter/rectifier. The switching pattern of BIC is provided from two power control loops and one voltage loop (Vdc) based on the DQ transformation theory. This control strategy allows, in a controlled matter, the transfer of both active and reactive power between the HMG and the public AC Grid. The fuzzy logic controller based on the fuzzy set theory provides a useful tool for converting the linguistic control from the heuristic or mathematical strategies; complex processes can be controlled in many situations effectively. But the most important and difficult point is how to obtain the proper control rules for a given system in the matter of fuzzy logic. In this paper, power factor correction is corrected to demand value by using a fuzzy logic controller under load changing for the electric power control system containing current unbalance i.e. load asymmetry. In the control system, reference reactive power value is determined by Fuzzy at various times of day as load changes with rising or falling trends.
