Advanced Power Control Strategies and a Homogeneous Novel Concept of AC-DC Micro Grids

Shruti Ganvir, Pratik Ghutke

Abstract


The simulation modelling and control of hybrid AC/DC micro grids are proposed in this article. The micro grid design eliminates multiple reverse switches from a Grids (AC or DC) and streamlines is independent grids. Connections to variable regenerative AC and DC sources and loads in the electrical system. Digital use of power electronic converters to connect to the utility / grid has raised questions about device safety and protection. The proposed hybrid AC/DC micro-grid system's performance can be assessed in both grid-tied and autonomous modes. Microgrids are developed using photovoltaic systems, wind turbine generators, and batteries. The AC sub-grid is correctly coordinated with the DC sub-grid, and the control mechanism is applied for converters for sensitive power transfer. This work investigates power flow control and management difficulties in ac and dc microgrids with numerous sources. The study presents a decentralised power sharing approach that eliminates the requirement for DG or microgrid communication. This hybrid microgrid architecture enables different ac or dc loads and sources to be flexibly positioned, reducing the number of required power conversion stages and hence the system cost and efficiency. The proposed power regulation strategy's performance is validated for various operating situations utilising Simulation experiments in the MATLAB / SIMULINK environment.
