Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation. [Online] Thesis for the Degree of Licentiate of Engineering

This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power and models for these energy sources are presented. The solar power model is based on the solar declination and cloud coverage. In addi-tion a Markov theory based model for simulating cloud coverage data is presented. The wind power model is based on two Markov chains, one for low wind and one for high wind. Both the solar and the wind models use measurements as input but by using normalised wind speed measurements a more general wind speed model is obtained. There are still, but minor, needs for site-specific meteorological measurements. The presented models of solar and wind power are together with some simpler models of hydro power, storage and loads used for case studies. Since the solar model is de-pendent on the location, a site in Africa is used. Timbuktu in Mali was chosen for its subsahara climate and the fact that Mali is considered a developing country. Twelv
