Improvement in the computational efficiency of a technique for assessing the reliability of electric power systems based on the Monte Carlo method

Krupenev D., Boyarkin D., Iakubovskii D. Improvement in the computational efficiency of a technique for assessing the reliability of electric power systems based on the Monte Carlo method // Reliability Engineering and System Safety. Vol.204. ID: 107171. 2020. DOI: 10.1016/j.ress.2020.107171 The reliability of energy systems is assessed to control their operation and expansion. An effective method for reliability assessment is the Monte Carlo method. This process, however, is often time-consuming...

Optimization of adequacy of electric power systems in market conditions

... electric power system under market conditions, which involve confrontation of various interests of market participants. This feature makes unsuitable of traditional methods for optimization of the reliability of electric power system. We carry out the reliability analysis of the variants of development of electric power system based on of the Monte Carlo method. We calculate the profit of generating companies by the obtained reliability indexes, which characterize some variant of electric power system ...
