Research on the Strategy of Integrating Photovoltaic Energy
In order to meet the needs of railway green electricity, this paper adopts photovoltaic power generation instead of traditional thermal power generation. This p
At the same time, this paper analyzed the application of photovoltaic storage system in new rail transit traction power supply, explored its technical advantages and implementation solutions, and ensured that the system can operate stably for a long time under photovoltaic and load fluctuations.
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.
From this, we can know that in any region of China, the grid connection of photovoltaic power generation and rail transit power supply system is feasible. Even more, it has great development space. Literature, respectively take Shenzhen Metro Line 6 and Guangzhou Metro Yuzhu depot as examples.
However, due to the randomness and uncertainty of photovoltaic power generation, the direct access of photovoltaic power generation to rail transit power supply system will bring a certain impact on rail transit power supply system. It will directly affect the power quality and the stability of the grid.
