Transportation is one of the most important infrastructures in today's developed societies; And easy, safe, convenient, and economical transportation comes first. Intercity and suburban railways are some of the most important ones. To realize the green economy, which means to synchronize today's economic world with the environment and the use of natural resources, we are witnessing the growth of electric transportation such as electric railways. In general, railway electrification paves the way for increased productivity, reduced operating costs, increased investment utilization, reduced environmental pollution, no need to keep engines warm at standstill, increased average speed, and the possibility of using regenerative braking energy to save. In the meantime, the issue of how to electrify railway networks is debatable. The existence of extensive networks for the transmission of electrical energy from distant places to consumption centers is one of the characteristics of the current electrical networks in the world. This network configuration causes many problems and calamities, such as loss of electrical energy over long distances, as well as threatening the stability of the network. On the other hand, the existence of distribution networks that are fed only through these transmission networks always exposes these networks to blackouts and instability. One of the leading solutions to overcome these problems is the use of renewable energy resources such as solar panels, wind turbines, etc. The optimal and desirable method of connecting these resources is the concept of the microgrid.
In the present dissertation, to implement the green electric rail network and increase its reliability and stability, we will design an electric rail microgrid connected to distributed generation such as solar panels in MATLAB / Simulink environment. Given that the presence of microgrids and uncertainty in renewable sources has created new challenges in the power system, we will continue to design a control system to manage the power distribution and power supply of the railway despite changes in environmental conditions in the microgrid.
