Clustering power system approach with smart distribution network controller

Abstract

The ongoing trend to sustainable energy supply based on renewable energies is coming along with new challenges in network control. Especially in the low voltage distribution networks, new control structures are required, since they have been considered as a passive system in regards of network control. As a feasible solution for structuring power networks the Clustering Power System Approach (CPSA) has been introduced, in order to allow adequate control architecture. This paper focuses on a new network control application for clustered power systems, being suitable for directed manipulation of power flows in low voltage networks. The core component is a smart inverter system in combination with a battery storage, which will be placed into the connection lines between interacting clusters. The network control application is introduced in this paper and initial results of the capabilities of the smart inverter system, especially at asymmetrical grid conditions, are presented.
