Evaluation of an urban medium-voltage network by using reliability indices

The paper proposes a procedure to assess the reliability indices needed in evaluating an urban mediumvoltage network. There are several ways of determining the reliability indices describing the network in its current state as well as the potential changes caused by reinforcing the electrical installations, implementing restructuring measures or increased generation and demand in the network structure. For the calculations to be efficient the input data for the created reliability datatypes and values should be used correctly. By employing the reliability indices, an impartial comparison between various here given options is possible.
