What is it about?

The electrical system is a system of interconnected components that allows generation, transmission, and conversion of electrical power to serve the actuators, pumps, drives, starters, electronic equipment, etc. (all electrical loads). This journal proposes an optimization problem in order to find out the scheme of interconnection and the necessary number and type of components in order to have a functional electrical system. There are some mathematical constraints that allows a certain degree of reliability depending on the initial requirements of the designer.

Why is it important?

This proposal shows that an electrical system can be defined at a functional level by solving an optimization problem. The advantage of this approach is that it can get closer to a final implementation by successive refinements, i.e. increasing the level of functionality with respect to the previous synthesis. For example, in the first two steps the outcome is an architecture of an electrical system where converters functionality is depicted as voltage level converter; in the next refinement, converters topology can be defined holding the same functionality it had in the previous steps, but introducing new dynamics as it approaches to a physical implementation.

This article has been an effort to provide mathematical tools that can be used in optimization packages and commercial solvers for the development of disruptive and innovative solutions for aerospace technology. This approach reduces the amount of effort in producing an architecture, which is usually assessed with a significant amount of resources and requires an advanced level of expertise in reactive synthesis.
