“…Thus, it is vital to estimate the battery degradation for the operation and maintenance of BESS stations. This degradation process depends on multiple factors, such as C-rate, DoD, SoC, SoC, temperature, humidity and charging state transitions (Wang et al, 2016). In this study, an aging modeling for each battery container is established to calculate its capacity degradation considering several influential parameters of SoC, DoD, temperature and state transitions.…”

A grid-scale battery energy storage station usually contains multiple battery containers and corresponding electric links. Each link and battery container could become a controllable subsystem when receiving network operators' orders. Battery containers will perform differently after long-term use, especially considering a mixed utilization of new and recycled batteries. Currently the storage inflow/outflow power is distributed equally among containers. The existing power allocation and control strategy in battery energy storage stations mainly focus on batteries' capacity constraint, rather than their performance, temperature, and aging conditions. This paper proposed a novel power allocation approach for multiple battery containers in a battery energy storage station considering batteries' state of charge, temperature, and potential aging caused. This method established the mathematical modeling between battery aging with state of charge, depth of discharge, operating temperature and charging state transition times, thus the potential battery aging can be accurately calculated. The battery aging is used as the optimization objective to ensure the total battery aging occurred in all containers is minimized when executing every power dispatch order. A methodological framework is conducted based on a pure-simulation case study to evaluate the potential benefits and aging risks of different power allocation strategies. The simulation results showed this novel method helps to balance the aging, temperature, and state of charge between battery containers, leading to a more reliable, and secure operation of battery energy storage station.

“…Figure 2 shows the number of cycles versus DOD for a nickel manganese cobalt oxide (NMC) battery, a commonly used storage chemistry for small-scale behind-the-meter applications. The figure is based on references [13,14] where a least square fitting method was applied to test data. Cycle life versus depth of discharge (DOD) for a nickel manganese cobalt oxide (NMC) battery, based on data from [13,14].…”

“…However, a battery is not always operated using regular cycles. This is especially true for behind-the-meter applications, where the battery operation is largely dependent on signals received from outer factors such as the energy price, power demand, and local power production [13]. It is therefore necessary to build a cyclic degradation model which reflects the irregular behavior of the battery.…”

The cost of peak power for end-users subject to a demand charge may be substantial, expecting to increase further with the vast growth of power-demanding devices. In cases where load-shifting is not a viable option for cost reduction, battery storage systems used for peak shaving purposes are emerging as a promising solution. In this paper, the economic benefits of implementing battery storage into an existing grid-connected photovoltaic system for a medium-scale swimming facility is studied. The objective is to minimize the total cost of electricity for the facility, including the cost of energy and peak power demand, while ensuring the longevity of the battery. An optimization model based on multi-integer linear programming is built, and simulated using a one-year time horizon in GAMS and Matlab. The main results reveal that installing a battery storage system is economically attractive today, with net savings on the total system cost of 0.64% yearly. The cost of peak power is reduced by 13.9%, and the savings from peak shaving operation alone is enough to compensate for the yearly cost of the battery. Moreover, the battery ensures additional revenue by performing price arbitrage operations. When simulating the system for an assumed 2030 scenario, the battery is found to be more profitable with a yearly net savings of 4.15%.

Growing penetration of wind power challenges to power system security, since the conventional generators may not have sufficient capacity to compensate wind power fluctuation plus the reverse peak regulation. In this paper, the high-capacity pumped-storage and fast-response battery-storage are coordinated to compensate the variation of both wind power and load, aiming at shifting peak load, responding to wind power ramping, reducing the curtailment of wind and stabilizing the output of thermal units. A practical framework is designed for optimizing the operation of the hybrid system consisting of the wind, pumped-storage, and battery storage, which can take full advantages of pumped-storage and battery-storage. The detailed mathematical formulations of the pumpedstorage and battery-storage are built. Three cases are studied to demonstrate the advantages of the proposed coordination method.
