Development of a 'smart' power network for the AUV hybrid power generation and distribution system.

A hybrid system for generating and distributing electricity for a multi-speed autonomous underwater vehicle is considered. Due to the wide range of electricity consumption, the task of controlling the parameters of the power grid arises. The complexity of the task lies in the constant change in the composition of consumers and the current they consume. Due to the novelty of the development of a multi-speed apparatus and the use of a hybrid system for the generation and distribution of electricity, the problem was not considered earlier in this formulation. To solve the problem of connecting consumers to power sources, it was presented in the form of a weighted directed graph, and the problem of connecting consumers to conductors was formalized as finding the shortest path in the graph. The paper proposes algorithms for controlling the connection / disconnection of consumers from the elements of the electrical network and the dynamic switching of consumers between current conductors, depending on the speed mode of the apparatus, based on the use of an algorithm based on Dijkstra's algorithm. The results of numerical experiments made it possible to estimate the energy consumption in the most unstable, most energy-intensive parts of the trajectory. This made it possible, in turn, to test the developed power grid control algorithms and make sure that the algorithmic decisions made were correct. [ABSTRACT FROM AUTHOR]
