Due to the pollution of the traditional power generation resources and environmental problems, development of power generation resources has become a major problem in today's world. Because of this reason and economic reasons for fossil fuels, the electricity industry designers and policy-makers are to provide solutions to improve the current situation and to reduce destructive environmental effects. In the meantime, the use of renewable resources such as wind and solar power plants has been a priority of many governments and companies. Because of the uncertainty of the renewable energy resources and their dependence on weather conditions, their influence is along with some problems... 

Well-Being reliability indices (Health, Margin and Risk), provide a comprehensive measure to assess the adequacy of composite power systems. Conventional reliability information about power system operation only considered health and risk states, which were not often adequate criteria in both power system planning and operation. Well-being approach for power system generation adequacy evaluation incorporates deterministic criteria in a probabilistic framework, and provides system operating information in addition to risk assessment and can be evaluated using analytical techniques. The most important part of this approach is the algorithm for calculating the probability of the states....
