The relevance of the study is due to the development herein of a model for reliability
optimization of stand-alone power systems with wind turbines and electrochemical power storage
devices, with special emphasis within this model put on the specifics of power equipment operation.
The key feature of the model developed is that it enables us to factor in the requirements to be met by
the equipment as arising from the considerations of dynamic stability of the stand-alone system. When
simulating battery storage operating modes, the charge-discharge limits as well as the remaining
charge in the storage are taken into account. Thus, the reduction of the total number of considered
mixes of the equipment being commissioned is achieved, the computational efficiency of the reliability
optimization method is increased, while the validity of modeling results is improved. Development
of methods for optimization of reliability of stand-alone electric power systems with wind turbine
installations and electrochemical power storage devices while meeting requirements for electrodynamic
stability. A stand-alone power system that is assumed to be located in the coastal area of Lake Baikal
in the Kabansky State Nature Reserve, Republic of Buryatia, Russia, serves as the object of the study.
Calculations are based on multiple simulation of modes of operation of the electric power system
by means of the Monte Carlo method. The values of random variables are modeled as per specified
laws of distribution and fault rate indicators of power equipment. Modeling of power generation at
wind turbines is based on a detailed analysis of real-life weather data (average hourly wind speed,
air density and humidity). The method of reliability optimization of stand-alone power systems with
wind turbines and electrochemical energy storage devices was developed so as to take into account the
requirements to be met by electric power equipment in terms of dynamic stability. The optimization
criterion is the minimum expected value of the cost of produced electricity. Power redundanct and
energy storage devices are used as means of reliability assurance. The results of calculations attest to the fact that for the natural and climatic zone under consideration, the use of vertical axis wind turbines
in a stand-alone power system proves more efficient than the use of horizontal axis wind turbinesΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ ΠΎΠ±ΡΡΠ»ΠΎΠ²Π»Π΅Π½Π° ΡΠ°Π·ΡΠ°Π±ΠΎΡΠΊΠΎΠΉ Π² Π΄Π°Π½Π½ΠΎΠΉ ΡΠ°Π±ΠΎΡΠ΅ ΠΌΠΎΠ΄Π΅Π»ΠΈ
