Optimal design of electric energy distribution systems: multiobjective mathematical modelling

Electric energy distribution system design models have usually considered a single-objective function (total cost of the power system expansion) subject to some common constraints such as the power demand requirements (Kirchhoff's current law constraints) and maximum power capacity constraints of feeders and substations. Multiobjective mathematical programming models are able to include the above mentioned design aspects as well as other important aspects such as, for example, reliability evaluations (mainly in terms of service continuity), the optimal voltage profile in the network, social and environment conditions (community aesthetic values; atmospheric conditions as in areas with atmospheric pollution; geographical conditions such as rivers, lakes, roads, highways, railroads, etc. that are present in the study area; legal regulations such as codes, standards and ordinances from local or national governments) and financial considerations (allowed budgets for system expansions)
