Are battery energy storage systems a suitable solution for wind turbine inconsistency?

Abstract— Probabilistic and intermittent output power of wind turbines (WT) is one major inconsistency of WTs. Battery Energy Storage Systems (BESSs) are a suitable solution to mitigate this intermittency which use to smoothen the output power injected to the grid by such intermittent sources.

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.

How do I determine the size of my battery bank?

To choose a battery bank, first calculate your daily power consumption. Then, decide how many days' of backup power you would like and multiply the power consumption figure by the number of backup days. For example, for 2 days of backup: 2000 Wh/day x 2 days = 4000 Wh. Ideally, a battery bank should be able to supply power even if there's a problem with the solar panels or charge controller.

What is power capacity value?

Capacity Value ($): The monetary value of the contribution of a generator (conventional, renewable, or storage) to balancing supply and demand when generation is scarce. Operating Reserves and Ancillary Services: To maintain reliable power system operations, generation must exactly match electricity demand at all times.

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.

How do you calculate energy consumption in Wh/day?

To calculate daily energy consumption in Wh/day, multiply the power consumption in Watts (W) by the number of hours (h) the device is used. e.g. 4 x 100W lights used for 5-hours a day = 2000Wh/day.
