摘要

The modern power systems include a larger number of more dispersed and smaller power generating sources, which are slowly replacing larger and more concentrated power sources. The objective of this paper is to analyse the replacement of nuclear power plant with wind power plants to compare both cases from the viewpoints of power system reliability. The load diagram and the variability of the power plants, whose power depend on the environmental parameters with the time is considered. This paper is focused on the loss of load expectation. The upgraded method considers plant power as a function of the time instead of its nominal power. Initial real power system model consists of twelve power plants including one nuclear power plant. This plant is then replaced by three wind power plants with their total power five times larger than the power of the nuclear power plant. A comparison of reliability in terms of comparing the loss of load expectation is performed using the real weather data for one calendar year. The results show that the replacement of the nuclear power plant with several wind power plants with wind power capacity five times larger than the nuclear power capacity causes a decrease of the power system reliability.
