Optimal redundancy of radial distribution networks by criteria of reliability and information uncertainty

The model is based on the criteria of cost-effectiveness and information uncertainty. The created model has a fundamental difference from the current classical economic-mathematical models. It is proposed to use the mathematical expressions of the information entropy determination of two states of the system: operable and non-operable as the constraints. These expressions are the constraints imposed in the task that creates an optimal radial network with redundancy. Expressions are constructed as all the elements reserving each other are similar, i.e. they have the same performance. The given example shows how to calculate the information entropy where a constraint is a problem solution, as well as the possibility of both applications of probabilities and numerical values for the information entropy determination is proved.
