Model of adequacy optimization of electric power systems under market conditions

... system node and equilibrium price of electricity according to Cournot model. For the next stage failures of power generating equipment and transmission lines are simulated. We also estimate of electricity shortage in a current hour on the second stage. Reliability indexes and profits of generating companies are formed after a whole cycle of computations. Values of a profit are depended on reliability of electricity supply. Simulation of random values is carried out by the Monte Carlo method. © 2018 ...

Impact of deicing agents on heat network corrosion

... infrastructure. The main objectives of this research were to assess the impact of the deicing agent on initiation and acceleration of corrosion of the heat network equipment (pipelines, nonmobile and sliding bearings), the effect of this corrosion on reliability of heat supply to consumers, and to determine the economic damage caused by the decline in service life of pipelines. In addition, the study identified additional circumstances of the detrimental effect of deicing agents on the heat network ...
