DMS impact on the technical and economical performance of the distribution systems

In the new conditions of the fast growth of decentralized generation, electric market liberalisation, and of the last numerous blackouts it is expected a dramatic change in the management and operation of the electricity grids worldwide. In distribution level the historic passive distribution network operation will vanish and a new active distribution network operation will be indispensable. On these terms beside other steps the implementation of a SCADA/DMS system and the maintenance of the relevant data is required too. In the present work the implementation impact of the Distribution Management System on the technical and economical performance of the distribution networks is investigated. Results show that even the expensive implementation of the SCADA/DMS, which provides state-of-the-art operational and technical support, the investments will be paid back in the first exploitation years.
