A Three-Phase Open Hardware Design for Power Quality Solutions

Abstract

Distribution System State Estimation has great potential in the integration process of renewable energies, energy storage and active participation of the customers. The international state of the art pilot projects showed that there are many use cases, such as indication of operational limit violations and enhancing strategic development and asset management by useful in-depth information about the electrical behaviour of the system. However, the concept of state estimation at the distribution level is still a developing research area due to the structural differences of the network structure and parameters from the transmission applications which is also discussed in detail. Based on the value proposition identified through the literature review, simulation studies are carried out on distribution test system with different scenarios based on renewable penetration levels and measurement data availability. The main contribution of this research is a conceptual overview of the possible application of distribution system state estimation and validation of the operation on a case study, which could serve as a foundation for testing the proposed viable use-cases.
