The flexible traction power supply system (FTPSS) eliminates neutral zones (NZs) but leads to increased complexity in power flow (PF) coordinated control among multiple traction substation (TS). To address the challenges, a power dispatch methodology based on TS clusters for FTPSS is proposed, involving decentralized local phase angle control within each TS cluster. The methodology consists of three stages. In the first stage, the TS cluster is transformed into an equivalent model with a fixed topology, allowing the power dispatch problem to be formulated as a set of numerical equations. In the second stage, utilizing the feasible phase angle domain (FPAD) calculation method, active and reactive power circulation (RPC) is either entirely suppressed or precisely constrained within specified tolerances. In the third stage, reference phase angles (RPAs) are determined based on the specified power dispatching mode. All stages are addressed using a unified trust region with dogleg path numerical optimization algorithm, which completely eliminates online PF calculations. Simulation studies demonstrate that the proposed method enables PF management under various dispatching modes for traction loads and regenerative braking energy with low computational delay, while also effectively suppressing power circulation, thus enhancing the flexibility and real-time performance of TS power coordination dispatch within FTPSS.
