Should substations include battery storage?

By incorporating battery storage, substations can ensure a continuous and reliable power supply, even during emergencies. Maintenance programs must be expanded to include electrical substation maintenance routines specific to energy storage interfaces. Visit our Substation Maintenance training course.

What are battery storage power stations?

Battery storage power stations are usually composed of batteries, power conversion systems (inverters), control systems and monitoring equipment. There are a variety of battery types used, including lithium-ion, lead-acid, flow cell batteries, and others, depending on factors such as energy density, cycle life, and cost.

What is an energy storage system?

An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

How much power would a 7 line substation use a day?

Peak demand on the 7 Line is approximately 26 MW for 2 hours, twice per day. A 25% reduction in demand would require a total of 26 MWh of storage recharged overnight. Control would be based on power draw at each individual substation. Figure 11. Power Demand at the Roosevelt Avenue and 78th Street Substation During a Weekday
