Modeling the Reliability of Electric Power of an Energy Hub Considering Critical Situation

With the development of energy converters and storages، the issue of multi-carrier energy hubs has been considered. At these hubs، various forms of energy such as electricity، gas and heat can be converted to one another through the converters. Given the substitution possibility of different forms of energy، reduce the cost and increase reliability of power supply system، which are the main advantage of energy hubs. In this paper، an energy hub including multiple sensitive loads is considered and reliability of its energy systems is modeled using Markov Chain and sequential Monte Carlo. In the proposed model، a method is presented for modeling failure rates in critical situations. The proposed model can be employed in planning studies to evaluate the adequacy of power supply system and using it، the appropriate capacity of each of the system components can be evaluated. Finally، simulation results of the proposed model on a test system are presented.
