6 FAQs about [Allowable discharge power of energy storage]
What is a battery energy storage system?
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Can energy capacity and discharge power capacity be varied independently?
In our exploration of the LDES design space it was assumed that the three scaling dimensions, that is, energy capacity, discharge power capacity and charge power capacity, can be varied independently, even though all three degrees of freedom are not possible for certain technologies.
What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
What is the optimal storage discharge duration?
Finally, in cases with the greatest displacement of firm generation and the greatest system cost declines due to LDES, optimal storage discharge durations fall between 100 and 650 h (~4−27 d).
What are the performance parameters of energy storage capacity?
Our findings show that energy storage capacity cost and discharge efficiency are the most important performance parameters. Charge/discharge capacity cost and charge efficiency play secondary roles. Energy capacity costs must be ≤US$20 kWh –1 to reduce electricity costs by ≥10%.
What is the allowable range of a battery SoC?
In the demonstration project, the allowable range of the battery SOC is usually set between 20% and 80%. Under this mode, the depth of discharge of the energy storage system is generally within 60%. Figure 10 shows the test result for tracking reactive power plan by using BESS. The blue curve is target and the red curve is actual reactive power.
