This research work is innovative and consists in proposing a full optimisation model based on mixed-integer non-linear programming considering the Pareto front technique. The goal is to achieve a reduction in repair times of the distribution networks components, while minimising the costs of that reduction as well as non-supplied energy costs. The optimisation model considers the distribution network technical constraints, the substation transformer taps, and it is able to choose the capacitor banks size. A case study based on a 33-bus distribution network is presented in order to illustrate in detail the application of the proposed methodology.engPareto optimisationCost reductionDistribution networksInteger programmingInvestmentNonlinear programmingPower capacitorsSubstationsTransformersjournal article10.1049/iet-gtd.2014.1196
