A Survey on State Estimation Techniques and Challenges in Smart Distribution Systems
For researchers and utility engineers, this paper consolidates existing DSSE knowledge but offers no new results or comparisons.
This survey reviews distribution system state estimation (DSSE), covering problem formulation, pseudo-measurements, meter placement, topology, renewable impacts, and cybersecurity, providing insights into achievements and future directions.
This paper presents a review of the literature on State Estimation (SE) in power systems. While covering some works related to SE in transmission systems, the main focus of this paper is Distribution System State Estimation (DSSE). The paper discusses a few critical topics of DSSE, including mathematical problem formulation, application of pseudo-measurements, metering instrument placement, network topology issues, impacts of renewable penetration, and cyber-security. Both conventional and modern data-driven and probabilistic techniques have been reviewed. This paper can provide researchers and utility engineers with insights into the technical achievements, barriers, and future research directions of DSSE.
