Distributed Control Method for Power Sharing in an Islanded AC/DC Microgrid System

The most essential and challenging task in an islanded AC/DC Microgrid is to achieve the proper power sharing because both AC sub-grid and DC sub-grid are present. In recent years, research in islanded AC/DC microgrid is widely emerging among researchers all around the world due to the availability of large number of distributed energy resources (DERs). The interlinking converters plays a very important role for balancing the power sharing in an islanded AC/DC microgrid system. The main aim of this paper is to achieve the proper power sharing among all the AC and DC distributed generators (DGs). This paper presents a consensus based distributed control method of interlinking converters (ILCs) for attaining a proper power sharing in an islanded AC/DC microgrid. The proposed control approach is also used to regulate the voltage of DC sub-grid and the frequency of AC sub-grid at their nominal values. In the end, MATLAB/Simulink Model is used for the implementation, analysis, and results verification of our system.
