An overview of inertia requirement in modern renewable energy sourced grid: challenges and way forward

Abstract As the world strives toward meeting Paris agreement target of zero carbon emission by 2050, more renewable energy generators are now being integrated into grid, this in turn is responsible for frequency instability challenges experienced new grid. The associated with modern power grid identified research. In addition, a review on virtual inertial control strategies, inertia estimation techniques system, modeling characteristics storage systems used providing support to and system operational expansion planning given. Findings study reveal that adequate essential mitigate instability, thus, considering requirement model will be key ensuring grid’s stability. Finally, direction future research has been from study, while an constant between 4 10 s recommended ensure stability
