Reliability modelling of a grid integration system with dual operational and quintuple critical systems

The current crisis of environmental pollution and depleting resources has led to a rise in the demand for renewable energy sources and systems functioning on such resources. However, their variable and unpredictable nature has challenges on its own. A grid integration system can help in maintaining and intensifying system stability and reliability by managing flexible renewable energy for future purposes. This work is based on a generic model of a grid integration system that takes into account all of its important components, both critical and non-critical. By classifying the components according to their failure properties, an analytical reliability model has been used to assess the reliability features of the whole system. The complete system has been categorized into two major systems, operational system and critical system. The system’s reliability characteristics including availability, mean-time-to-failure and sensitivity have been calculated to observe the performance of the complete system and its failure possibilities. Overall, an attempt has been made to study the significance of each component using past literature and a mathematical model based on the Markov Process property.
