An advanced control system for wind/diesel power systems

International audience; In this paper an advanced control system for the optimal operation and management of medium-sized autonomous wind-diesel power systems is presented. This control system minimises the production costs through an on-line optimal scheduling of the power units, which takes into account the technical constraints of the diesel-units, as well as short-term forecasts of the load and the renewable resources. The power system security is maximised through on-line security assessment modules, which enable the power system to withstand sudden changes in the production of the renewable sources. The control system was evaluated using data from the island of Lemnos, where it has been installed and operates since January 1995.
