Evaluating the Role of Power Electronics in Enhancing Renewable Energy and Smart Grid Performance: A Review

The review article demonstrates the importance of power electronics in propelling the increase of renewables and increasing the efficiency of contemporary electrical grids. In particular, it highlights the need for bidirectional converters for effective energy management in vehicle-to-grid (V2G) systems with two-way power transfer. The paper examines the series of complications offered by the significantly large integration of power electronic converter-interfaced renewables, such as those related to system steadiness, power quality, and resignation bottlenecks. Also, it recognizes a mix of new technologies, such as wide bandgap (WBG) semiconductors like silicon carbide (SiC) and gallium nitride (GaN), that deliver superior performance compared to traditional siliconbased devices. The review paper also covers the current trends in power electronics, control strategies, and energy storage systems using electric vehicles/hybrid systems. A comprehensive overview of the field has been presented by discussing the dynamic interaction between technological advancement and regulation frameworks, which outlines a broad view of sustainable energy systems in terms of power electronics. Furthermore, it highlights once more the importance of breaking down other barriers so that the much-needed transitions to low-carbon/highrenewable energy grids can take place and an affordable and reliable yet also sustainable and resilient future can be ensured.
