In a hybrid microgrid with AC and DC subgrids, the interlinking converter (IC) is the key element connecting the two subgrids. The performance of the interlinking converter is adversely affected by the d- and q-axis impedance interaction between the inner control loops. This interaction is highly undesirable since it adversely affects both the dynamic and the steady-state performance of the IC. Based on this, a novel feedback-based decoupling strategy is developed to overcome the cross-coupling effect in the mathematical model of the interlinking converter. This is a novel concept since the feed-forward compensation techniques are utilized to address the cross-coupling effect in prior related works, which has an inherent disadvantage of additional disturbance due to the addition of the compensating terms. In this study, a complete decoupling of the d and q axes was achieved, and the first-order transfer functions were obtained for the control loops using systematic block-reduction algebra and direct synthesis approaches. With this model, computational complexities are reduced and the inner control loops are free from impedance interaction effects, thereby achieving enhanced transient stability. Perfect decoupling of the voltage vectors is achieved by the matrix diagonalization method. Furthermore, the novelty of the proposed control is that the decoupled model is integrated with a normalization-based coordinate control strategy for effective bidirectional power transfer via the interlinking converter. Additionally, the proposed controller’s validity was tested for its performance under different transients in the MATLAB Simulink platform. The simulation results validated the proposed control strategy by showing that a faster response is ensured. A high-quality reference signal is generated due to the effective decoupling achieved. This observation was also validated by comparing the T.H.D. levels of a decoupled model’s reference power signal to one without a decoupling strategy.

The Energy management in Micro-Grid system is one of the most irrefutable issues in micro grid technology development. The Micro grid energy system consists on non-conventional resources, unit with storage energy and islanded or grid connected mode of operating loads. This tabloid presents a Micro-Grid energy management system for distributed generation connected MG with hybrid energy storage system. Hybrid energy storage system is achieved by combining the Ultra-capacitor and battery storage. The proposed energy management system in micro grid with hybrid energy storage system follows the two techniques, such as forecasting and optimization. Prediction of solar irradiance, load demand and temperature are coming under the Forecasting technique. For the economical operation in a grid connected micro grid the optimal dayahead scheduling of power generation and load demand is performed by the optimization technique. The MG will absorb or deliver the prespecified amount of power. In this method MG connected to the power grid in large numbers are integrated. The main intension of the energy management system is power balancing in the micro grid. The MATLAB/Simulink environment has been used to analyzing the effect of Energy management in micro-gird with hybrid energy storage system. The simulation results will show the effective and stoutness of the proposed energy management method.
