1. Introduction. By the end of 2020, the installed capacity of renewable energy power generation in China had reached 934 million kW, a year-on-year increase of about 17.5%, accounting for 44.8% of the total installed capacity [1].When a large number of renewable energies is connected to the grid, the inertia of the power system will be greatly reduced [2], [3].

to provide a loss breakdown by component.. The battery energy storage system achieves a round-trip efficiency of 91.1% at 180kW (1C) for a full charge / discharge cycle. 1 Introduction Grid-connected energy storage is necessary to stabilise power networks by decoupling generation and demand [1], and also reduces generator output variation, ensuring optimal efficiency [2].
It has been found that the power loss and efficiency of the ESS at rated power is 146 kW and 85% respectively. Furthermore, the mean time between failures of the ESS is 8 years and reliability remains at 73% after a year. The major cost impact observed is for battery and PCS as 58% and 16% respectively.

Tightening the SoC range to 20 to 80% extends the battery's lifetime to 5.6 years. The least stressing application is the FCR market, where the EoL is met after 18.4 years. To reduce the capacity losses, a liquid-based cooling system with a constant temperature of 25 °C is assumed for highly demanding applications.
Table 8 provides a description of the relevant literature on battery degradation factors. Additionally, battery pack degradation is dependent on the degradation of individual cells. Thus, if one cell in a battery pack degrades, it can lead to the failure of the entire battery.
