where R0 is the line resistance between the train and the last station (X/km); R00 is the grid resistance between the train and the next station (X/km); k is the resistive coefficient, the value is set to 0.019 X/km; d is the distance between the start and next stations; x(t) is the distance between the train and start station.

Substation transforms voltage from high to low or from low to high as necessary. Substation also dispatches electric power from generating stations to the consumption center. Electric power may flow through several substations between the generating plant and the consumer, and the voltage may be changed in several steps.

Furthermore, renewable energy generation stations (REGSs), energy storage stations (ESSs) and railway 10-kV power distribution systems The power supply distance of the traction substation in the system usually increases to 100–160 km (the distance between two traction substations). Therefore, the number of TSSs decreased

1. Introduction. Implementing modern smart grids necessitates deploying energy storage systems. These systems are capable of storing energy for delivery at a later time when needed [1] pending on the type and application, the period between the charging and discharging of these devices may vary from a few seconds to even some

The Fox Hills energy storage system, which is located next to our substation in the Rosebank neighborhood of Staten Island, furthers our clean-energy goals by storing 7.5 MW / 30 MWh of energy, including from renewable sources, such as solar and wind. That''s the equivalent of powering approximately 3,000 homes for 4 hours.

The electricity supply chain consists of three primary segments: generation, where electricity is produced; transmission, which moves power over long distances via high-voltage power lines; and distribution, which moves power over shorter distances to end users (homes, businesses, industrial sites, etc.) via lower voltage lines.

The impact of the increasing number of renewable energy power plants may cause the power grid to face an effect or change the flow pattern of power systems, for example, the reverse power, power
