Adaptation of Interconnection Policy for DGs to Increase Renewable Energy Integration in Mauritius

Variable renewable energy sources are taking increasingly larger parts in the local energy mix. The uncertainties induced on the Mauritian electric grid are reflected in unpredictable system wide voltage profile and frequency variations amongst others. To preserve power quality, reliability and stability measures need to be taken to mitigate impacts of these uncertainties. In this study a comparative analysis of the impact of a group of small DGs against the impact of a large DG of equivalent size is carried out. It was found that a group of small DGs dispersed in the network has lesser network losses that the equivalent sized single DG.
