Multi-level hierarchical control strategy for smart grid using clustering concept

Recently, the distributed generation (DG) based on renewable energy sources (RESs) is quickly penetrating and integrating into the power systems. Moreover, a large number of intelligent infrastructures are installed into the power systems in order to establish a future power system, called smart grid. However, the increased grid integration of these sources leads to significant structural changes for grid automation and control. Nevertheless, there are still no sufficient available strategies for active grid integration of the distributed generation units and their participation in grid control. A new flexible cluster control concept of the power system is required to ensure stable and secure operation. This paper introduces a multi-level hierarchical control strategy for efficient grid control for the distributed generation units. This proposed control strategy provides availability and reliability for future power systems.
