The goal of this research is to develop an optimization strategy using metaheuristic algorithms for component sizing of a SFCBES for a passenger train in India.
The Department of Energy of the US aims to increase the lifetime of fuel cells from 10,000 h in 2022 to 40,000 h in 2030 and ultimately 80,000 h [42]. As FCs are used in most of the commercial hydrogen train projects (as discussed in Section 4), we will focus on fuel cell electric trains.
In this study, we consider three platforms for decarbonisation, a battery electric locomotive (BEL), battery electric tender (BET) and a hydrogen electric tender (HET) (Fig. 2).Also shown in Fig. 2 are the usable energy capacities of these platforms (MWh), based on current commercial technology and future technologies expected to be …

The use of combined heat and power (CHP) systems has recently increased due to their high combined efficiency and low emissions. Using CHP systems in behind-the-meter applications, however, can introduce some challenges. Firstly, the CHP system must operate in load-following mode to prevent power export to the grid. …
Battery Energy Storage System (BESS) is capable of providing a contingency FCAS response using one of two methods: OFB), or its frequency control deadband (whichever is narrower); orVia a switching controller, where a step change in active power is triggered when the local frequency exceeds the Frequenc.

These are 16,000 rpm flywheels and the implied energy density is only 9.6 W h/kg. The flywheels have integral driving motors and inverters housed in a cylindrical cage approximately 1.06 m in diameter and 2.08 m high. In this application, 20 units are employed with aggregated ratings of 2 MW and 500 kW h.
The paper deals with the thermal management problem of an industrial battery energy storage system (BESS). To meet the demands of maintaining battery temperature in a suitable thermal range and ensure economical operation, we formulate the model predictive controller (MPC) using a linear model of BESS obtained from real-time data. Since the …

Energy storages for the flywheel and battery ESSs are 500 kWh and 5000 kWh, respectively. Traction performance, fuel consumption, and emissions were compared for the three simulated trains. The results show that, compared with the diesel train, the diesel-flywheel and diesel-battery trains were 13.26% and 9.20% slower in speed, …
These developments are propelling the market for battery energy storage systems (BESS). Battery storage is an essential enabler of renewable-energy generation, helping alternatives make a steady contribution to the world''s energy needs despite the inherently intermittent character of the underlying sources. The flexibility BESS provides …
