A novel two-stage distributed structure for reactive power control

Blog Article

In this paper, a new two-stage approach has been presented for the reactive power control of power systems.In the first stage, the transmission network is divided into several parts using a partitioning 7 Piece Counter Dining Set approach based on graph concept.In the second stage, a hierarchical distributed framework based on a System of Systems (SoS) concept has been proposed for optimal reactive power dispatch.

In this structure, every section of the grid is controlled by a smart agent.Agents are interconnected and exchange the required data via a telecommunication network.In this paper, the amounts of active and reactive power exchanged between agents are considered as boundary and common parameters.

Our proposed method is implemented on the IEEE 118-bus network connected to 7 active power distribution networks.The results are compared to the ones obtained from a distributed method based on an Incident Command System (ICS) and a centralized control method.It turns out that the proposed method outperforms the other Breast two competing methods.
