This study delves into the integration of photovoltaic (PV) and energy storage systems (ESS) into AC railway traction power supply systems (TPSS) with Direct Feed (DF) and Autotransformer (AT) configurations. The aim is to evaluate energy performance, overhead line current distribution, and conductor temperature.
Findings reveal improved voltage drops and significant reductions in substation supply power, energy consumption, contact wire current, and temperature. Notably, a 6.5% and 9.6% reduction in supply energy is observed with PV and ESS integration for DF and AT configurations, respectively.
To address these issues, this study proposes a novel planning framework for the co-deployment of DPV and hybrid energy storage systems (HESS) within an integrated rail transit green energy system, aiming to achieve synergistic coordination among the grid, generation, storage, and rolling stock.
Notably, a 6.5% and 9.6% reduction in supply energy is observed with PV and ESS integration for DF and AT configurations, respectively. These results underscore the imperative of the integration to optimize energy management in railway systems, fostering efficient energy utilization, potential cost savings, and environmental sustainability.
