6 FAQs about [Average charging and discharging efficiency of energy storage power stations]

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.

Does volatility of energy prices affect energy storage parameters?

For the analysis of energy storage parameters, a methodology was adopted assuming that the volatility of energy prices in a year in particular years results in slight changes in the optimal parameters of the energy storage.

How do you calculate battery efficiency?

Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.

What is the extension of arbitrage in power systems without electricity markets?

Another extension of arbitrage in power systems without electricity markets is load-leveling. With load-levelling, system opera-tors charge batteries during periods of excess generation and discharge batteries during periods of excess demand to more eficiently coordinate the dispatch of generating resources.

When should a battery be charged and discharged?

Often a battery is charged whenever resources are available and discharged whenever load occurs without going through a complete charge/discharge cycle, so a long analysis period (e.g., 1 year) may be needed to capture when the battery is completely discharged (to minimum set point) and completely charged.

How do I record charge and discharge data from a Bess meter?

3.1.2 Record of Charge and Discharge Data from BESS Meter. In order to be assessed, the BESS system must be equipped with a meter measuring charge into the battery and a meter measuring discharge out of the battery, or a single meter that can record both.
