How to calculate the peak-shaving energy storage capacity of a power plant

Can a battery energy storage system be used for peak shaving?

This paper presents an approach to determine the optimal capacity of battery energy storage system (BESS) for peak shaving of the electric power load in Naresuan University (NU), Phitsanulok, Thailand. The topology of the system consists of main grid, loads and the proposed BESS.

How to reduce peak load power in energy storage system?

This is done by considering the usage of energy storage system for peak shaving the peak load power. By increasing the BESS size, load peak can be efficiently reduced in the range of small BESS size (0-5 MWh). For a larger BESS size, the load peak can further be decreased but the decreasing rate is reduced.

How to save electricity cost by peak shaving?

An optimal BESS capacity for saving the electricity cost by peak shaving is calculated by first considering the date when the highest energy demand is recorded. Our results show that the optimal BESS can shave the peak load efficiently. Oversized BESS can further decrease the load peak but the reduced cost per battery capacity is not optimal.

Why do energy storage systems have peak load peaks?

ery Energy Storage System controlINTRODUCTIONElectricity customers usually have an uneven load p ofile during the day, resulting in load peaks. The power system has to be dimensioned for that peak load while duri

Can a finite energy storage reserve be used for peak shaving?

g can also provide a reduction of energy cost. This paper addresses the challenge of utilizing a finite energy stor ge reserve for peak shaving in an optimal way. The owner of the Energy Storage System (ESS) would like to bring down the maximum peak load as low as possible but at the same time ensure that the ESS is not discharged too

Does increased storage capacity affect peak shaving application?

It is an important question because the storage capacity shall be high enough to support the appropriate peak shaving operation for the coming years (or until the energy consumption exceeds the evaluated level). Therefore, it is interesting to analyze the effects of the increased consumption on the peak shaving application.
