Abstract: The present study describes and analyses a set of quasi-static railway power systems models and simulations considering on-board and off-board energy storage systems but also reversible and non-reversible substations and regenerative braking trains.
Why do we need Advanced SubStation technology?
Development of advanced substation technologies that enable new functionalities, new topologies, and enhanced control of power flow and voltage can increase the grids reliability, resiliency, efficiency, flexibility, and security.
Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.
Why is a substation important?
Demonstrating sufficient selectivity, sensitivity, speed, safety, and reliability will be critical to gaining acceptance by networks operators. Generally, the equipment within a substation has a significant impact on the architecture and design of protection systems.
On the path toward grid modernization are opportunities to improve the performance of substation components and to rethink the design of these critical nodes of the system. SSPS, a substation or “grid node” with the strategic integration of high-voltage power electronic converters, can provide system benefits and support evolution of the grid.
What are the most popular energy storage systems?
This paper presents a comprehensive review of the most popular energy storage systems including electrical energy storage systems, electrochemical energy storage systems, mechanical energy storage systems, thermal energy storage systems, and chemical energy storage systems.
Are substation applications valuable?
Advances in substation application will require heavy involvement from utilities to ensure that the target applications are valuable to the industry. However, the value of these applications will vary by region because of the multifaceted diversity in the U.S. electric power system.
