9. Conclusion

All articles on voltage quality and [D 4 264] may suggest that a solution can be found, either to reduce the number of disturbances that inevitably affect networks, or to mitigate their effects on a customer. Unfortunately, electricity networks in developed countries, which supply all the homes and industries in a region or a country, are "attacked" by natural phenomena or those linked to human activity. The laws governing the distribution of these phenomena cannot be reproduced, nor are they bounded.

As a result, it is impossible to determine an "optimum", in the mathematical sense of the term, as we are unable to capture the constraints, even statistically. At most, the constraints we can cover are those "within human memory", and the probability of occurrence of "exceptional" cases is not entirely zero.
