Abstract

In this article, a hybrid system that consists of a specified number of wind turbines and solar modules is considered. In particular, the system is modeled using weighted k-out-of-n system which is also known as a threshold system in reliability literature. The system under concern consists of $n_{1}$ identical wind turbines and $n_{2}$ identical solar modules, and each turbine and module can be in one of two states as working or failed. The probability that the entire hybrid system with $n = n_{1} + n_{2}$ components produces power at minimum level k is computed and evaluated. The importance of single-wind turbine and solar module is also calculated to measure which renewable energy component is more critical and important. Extensive numerical results that are based on real data set are presented to illustrate the model.
