6 FAQs about [Power system energy storage parameters]
What are the performance characteristics of a storage system?
K. Webb ESE 471 9 Efficiency Another important performance characteristic is efficiency The percentage of energy put into storage that can later be extracted for use All storage systems suffer from losses Losses as energy flows into storage Losses as energy is extracted from storage K. Webb ESE 471 10 Round-Trip Efficiency
What are the merits of energy storage systems?
Two primary figures of merit for energy storage systems: Specific energy Specific power Often a tradeoff between the two Different storage technologies best suited to different applications depending on power/energy requirements Storage technologies can be compared graphically on a Ragone plot Specific energy vs. specific power
What are the efficiencies of energy storage systems?
Here are some round-trip efficiencies of various energy storage systems: These numbers mean the following. For example, out of 1 MWh of energy spent to pump water up to the hydro storage, only 0.7-0.8 MWh will be available to use after the water is released to run the turbine and generator to produce electric power.
What type of energy is stored in different domains?
Energy stored in many different domains Input and output energy is electrical Three-phase AC power Conversion is required between the storage domain and the electrical domain Transformer Power conversion system (PCS) K. Webb ESE 471 27 System Configurations – Mechanical Mechanical storage Pumped hydro, flywheels, compressed air
What is power power?
Power Poweris an important metric for a storage system Rate at which energy can be stored or extracted for use Charge/discharge rate Limited by loss mechanisms Specific power Power available from a storage device per unit mass
What is a fully discharged power supply (SoC)?
The amount of energy stored in a device as a percentage of its total energy capacity Fully discharged: SoC = 0% Fully charged: SoC = 100% Depth of discharge (DoD) The amount of energy that has been removed from a device as a percentage of the total energy capacity K. Webb ESE 471 6 Capacity
