Guiding electricity distribution system investments to improve service quality: A European study

The transformation process for a more cost-effective electricity sector has also brought radical changes to distribution networks. In Europe, fundamental differences between distribution system operators (DSOs) might jeopardise the process by increasing present technological gaps. In this work, we identify those technological features having an higher impact on the quality of the supplied service. By focusing on the duration of electricity interruptions indicator, we provide statistical models that identify feasible technological options to improve DSOs performances. Our analysis is based on a subset of the non-confidential DSO Observatory project dataset counting almost 100 unbundled DSOs.
