Abstract : With the significantly rising demand for alternate energy resources like renewable sources, the power demands are fulfilled at reduced expenses, and increased efficiency. Despite these alternate generation techniques, there are still considerable challenges in controlling and working Microgrids (MG’s) configured in DC and AC. Hybrid Micro-Grids (HMGs) are developed particularly for overcoming the effective power regulation difficulties encountered in standalone MGs by combining the advantages of individual AC and DC configurations. Since microgrids are equipped with power electronic interfaces, unlike the conventional system, maintaining voltage stability, frequency stability, and optimal power management is challenging and requires a different approach. This paper attempts to analyze various stability issues in existing systems and the control methods employed in prior works for a better understanding and management of HMG systems. It also presents a comparative study of related works in terms of their control techniques and achieved performance. The paper further discusses various research challenges prevailing in this field thereby providing an insight into the development of better control methods and techniques for resolving various stability issues in HMG for better management and supporting future applications.
