A fuzzy-based power system reliability evaluation

Fuzzy‐based frequency security evaluation of wind‐integrated power systems

“…Fuzzy logic is introduced to emulate language-based decision making [24,25]. Until now, it has been used for the reliability assessment procedure, describing the probability of the system states to reduce the simulation burden during the assessment [26][27][28][29]. The fuzzy sets are thereby used to represent the system states' probability, such as load distribution or wind speed probability.…”

“…Therefore, the technique that can effectively calculate probabilistic distributions with less computational expense is considered. High proficiency and accuracy may be achieved in analytical methodologies by programming with different algorithms, either complicated or simple (Propst 1995, Abdelaziz 1999. The analytical method calculates the reliability indices of power system composites based on mathematical models and solutions (Hailei et al 2008, Ning et al 2006, Chen et al 1995, Billington and Allan 1996, and can significantly reduce the calculation time for large-scale power systems (Zhang and Lee 2004).…”

A hybrid methodology for restructuring decision of a manufacturing system: A case study

“…In this study, they have modelled the imprecision of the performance evaluation process as fuzzy numbers by means of linguistic terms. Besides, they have presented a performance evaluation study of 10 bus companies to illustrate the approach proposed, Abdelaziz [22] has suggested a fuzzy version for evaluating the reliability of complex power systems. In the proposed algorithm, Abdelaziz has used fuzzy set theory to evaluate the coefficients of different terms in reliability expression.…”
