Abstract


Rapid reduction of non-renewable sources of energy is driving development toward sustainability. Increased integration of distributed generation units, including renewable sources of energy and energy storage systems (ESS), has simulated research in new techniques of power generation. At the same time, integration of these distributed generation units in the conventional power generation setup has become challenging. To counteract these challenges, AC microgrid (ACMG). The Concept of AC microgrid Introduced (ACMG). To counteract these challenges, the concept of DC microgrid (DCMG) has been introduced. In attempting to determine and explain the available options for developing and constructing a microgrid, this paper conducts a thorough analysis of all these parameters for AC and DC microgrids. Protections, power converters, fiscal assessment, and abundance are a few of the topics and problems covered in the implementation and development. DCMG incorporates several power converters at the source-side and the load-side. There are certain stability issues related to these power converters that need to be investigated to ensure the overall stability of the DCMG and ACMG. This paper deals with the design of a simulation platform of a buck converter at the source side of the DCMG and ACMG. Such a simulation platform will be beneficial to study the stability of the DCMG and ACMG. The paper also shows the stability analysis of the developed simulation platform and calculation of its sensitivity function for robustness.
