An Intelligent Measurement and Control Device for Active Distribution Grids

This paper deals with the development of a unified system architecture that is able to provide both protection and control possibilities for the active distribution grids of the future. The paper focusses on the co-ordination of the developed protection and control algorithms on a power quality measurement device. The unified system utilizes decentralized measurements distributed across the distribution grid. Several functions are already implemented on the device. A hierarchical approach is followed by the voltage regulation algorithm. This means that in addition to a global master, there are several branches of the distribution grid and each of them has a sub-master system. When there is a trip activatied due to a fault, the trip information is communicated to the central master or the sub-master. The control algorithm at the master device neglects this part of the grid and takes necessary steps to ensure that the rest of the grid still remains protected and is under control. The algorithm is validated on a Cigré Benchmark medium voltage grid using a real-time simulator in a hardware-in-the-loop setup.
