Autonomous Renewable Energy Systems

MN Van Voorden, SO Ani, DON Obikwelu


This paper presents new ways of generating electricity from renewable energy sources and the development of the needed infrastructure for the next generation. The problems of having many renewable sources such as wind and solar generating units in a power system are uncontrollable fluctuations in power generation and the difficulty in forecasting the power generation capability of these sources due to their stochastic nature. Therefore, autonomous electricity systems with a high penetration of renewable energy sources are studied. A renewable energy laboratory DENlab is realized to analyse the autonomous application of renewable energy sources to a system of ten households (50 kVA). To have an opportunity to integrate other renewable sources with ease, a weak grid, grid-connected or a parallel operating situation can be created with small adaptations.
