Stabilized Power Management in the Microgrid Using Unified Delta Controller

摘要

The idea of reducing the transmission losses and encouraging the pollution free energy generation has increased the demand for microgrid systems throughout the world in the recent years. However, optimal utilization of sources along with overcoming the stability related issues in the MG system are to be taken care of. To address these issues, the state of art has presented various power management strategies and complex control techniques. In this regard, this paper aims to propose a novel delta based Controller for power management in the MG system comprising solar, wind battery along with DC and AC loads. Further, the proposed controller is also responsible for monitoring power stability and regulates DC and AC bus voltages in the MG system. This paper also proposes a transformer based MLI (TBMLI) whose secondary produces HVs and LVs simultaneously. The analysis of the TBMLI has been presented. The proposed δ-Controller has been validated for source and load intermittencies in the MATLAB/Simulink environment.
