Boosting efficiency in state estimation of power systems by leveraging attention mechanism

Energy and AI 2024年第2期16卷 438-449页

作者： Elson Cibaku.Fernando Gama SangWoo park Indu.trial Engineering New Jersey Institute of TechnologyNewarkNJUnited States Pendu.u. Systems DenverCOUnited States

Ensu.ing stability and reliability in power systems requ.res accu.ate state estimation, which is challenging du. to the growing network size, noisy measu.ements, and nonlinear power-flow equ.tions. In this paper, we introdu.e the Graph Attention Estimation Network (GAEN) model to tackle power system state estimation (PSSE) by capitalizing on the inherent graph stru.tu.e of power grids. This approach facilitates efficient information exchange among interconnected bu.es, yielding a distribu.ed, compu.ationally efficient architectu.e that is also resilient to cyber-attacks. We develop a thorou.h approach by u.ilizing Graph Convolu.ional Neu.al Networks (GCNNs) and attention mechanism in PSSE based on Su.ervisory Control and Data Acqu.sition (SCADA) and Phasor Measu.ement u.it (PMu. measu.ements, addressing the limitations of previou. learning architectu.es. In accordance with the empirical resu.ts obtained from the experiments, the proposed method demonstrates su.erior performance and scalability compared to existing techniqu.s. Fu.thermore, the amalgamation of local topological configu.ations with nodal-level data yields a heightened efficacy in the domain of state estimation. This work marks a significant achievement in the design of advanced learning architectu.es in PSSE, contribu.ing and fostering the development of more reliable and secu.e power system operations.
