Abstract
Distributed Generation is employed to enhance power stability. However, large integration of DGs can have adverse effect on power quality (PQ) such as voltage stability and harmonic pollution. Thus, jeopardizing the grid stability. Policies such as IEEE 1547 and 519 grid code standards (std) have been formulated to regulate and harmonize DG operations. Whilst IEEE std 1547 forbid DGs to partake in voltage regulation, IEEE 519 on the other hand limits the current drawn to a total demand distortion (TDD) not exceeding 5%. This policy will inevitably result in voltage instability and harmonic contamination if the DG power output surges. Although these policies help to mitigate the negative impact of DGs, there is no single solution that is most appropriate for a particular jurisdiction in addressing them. Therefore, to secure the future of the electric grid, there is a need to revisit the grid codes standards regulating DG operation.
