Distributed generation, clustering power systems, hierarchical control strategy, decoupling power system
Recently, large numbers of new decentralized energy conversion systems (ECSs) in combination with renewable energy sources (RESs) have been integrated into the conventional grid to build up sustainable energy supply systems. Moreover, a large number of intelligent infrastructures are installed into the power systems in order to build up “smart grid”. However, the increased grid integration of these sources leads to significant structural changes for grid automation and control. Nevertheless, sufficient available strategies for active grid integration of the distributed generation (DG) units and their participation in grid control are still unavailable. Therefore, this paper introduces a multi level clustering power systems concept for the distributed generation. The approach of multi level clustering power systems is giving an opportunity to establish an advance control function down to local level. According to this bright vision, the future power systems can be built up from bottom up approach, which is flexibility and modularity for DG integration in conventional grids. In order to figure out the clustering power systems concept, the required functionalities, the grid integration based on hierarchical control strategy, decoupling power systems, are taken into account in this paper. Furthermore, cases study shows how multi level clustering power systems are function and application.
