A new expert system based control tool for power systems with large integration of PVs and wind power plants

International audienceIn the present paper, an advanced control system for the optimal operation and management of medium size power systems with large penetration from renewable power sources (wind and photovoltaics) is presented. This control system is aimed to assist the power system operators in their management tasks, by proposing optimal actions to them for the economic and secure management of the power system. The control system is composed of various modules performing functions such as short-term forecasting of both load and of the renewable sources, economic dispatch of the power units and online dynamic security assessment. The pilot control system is being installed and evaluated on the Greek island of Lemnos
