Abstract (EN): This study presents a techno-economic robustness assessment over coordinated protection schemes using reclosers to leverage self-healing in distribution networks. A methodology to assess the optimal deployment of reclosers in overhead distribution networks is used to define the number and the strategic location of reclosers, in order to achieve the maximisation of the reliability improvement and the investment cost effectiveness. The methodology comprises a technical assessment over the service restoration feasibility through fault detection, isolation and restoration, and an economic assessment through a cost-benefit analysis over the equipment's life cycle. A real Portuguese distribution network is used to perform a case study comprising two scenarios of operation under contingency, a base case scenario and an additional scenario considering the presence of renewable energy sources - wind power plants. The advanced sensitivity analysis focuses on the evaluation of the optimal solution robustness to key parameters - technical and economic - such as the value of energy not supplied (ENS), the load growth rate and the value of the wind curtailment.
