Distributed OPF Solution via Sensitivity-Based Decomposition
Analysis
This paper addresses the computational challenges of large-scale Optimal Power Flow (OPF) problems, crucial for efficient power system operation. It proposes a novel decomposition method using a sensitivity-based formulation and ADMM, enabling distributed solutions. The key contribution is a method to compute system-wide sensitivities without sharing local parameters, promoting scalability and limiting data sharing. The paper's significance lies in its potential to improve the efficiency and flexibility of OPF solutions, particularly for large and complex power systems.
