Optimization of Technological Systems by Redundancy of the Main Structural Elements

The purpose of this paper is to offer a different approach to the optimization of a modernized power supply system with renewable energy sources (RES) at a predetermined level of reliability of ≥ 0.98 by using redundancy. The article examines two redundancy options based on the significance of the respective structural components in the power supply system. While the second structural element is more significant in the other variant, the first structural element is more significant in the first variant. The two main components of the power system under consideration each have a probability of failure-free operation of 0.8 and 0.4, respectively. When designing the entire power system, a methodology is used to determine the necessary number of backup components that will allow maintaining the specified level of reliability.
