“…Many technoeconomic studies consider battery degradation only through fixed upper and lower bounds for SOC and a limit on C-rate. 23,24 From a financialeconomic perspective such limits unnecessarily disallow potentially profitable operations. Ignoring other degradation mechanisms, typically leads to high resting SOC level and deep cycles, which are both harmful to battery life.…”

Batteries are crucial to manage the rising share of intermittent energy sources and variability in demand. Most technoeconomic models in the literature oversimplify battery degradation representation. Accounting properly for battery degradation allows for better cost tradeoffs and optimal battery usage, especially in dynamic settings. We propose a highly accurate and scalable formulation for battery degradation that considers the combined impact of cycle depth (CD) and state of charge on calendar and cycle aging. This includes a novel way to track charge‐discharge cycles. We test the consequences of battery degradation in a stylized price arbitrage model on battery operation and solution times. When ignoring battery degradation, ex post calculations reveal hidden degradation costs that exceed revenues and hence turn seemingly profitable trades into losing trades. Considering battery degradation leads to smaller CDs and lower average states of charge. Overall, we show that a much‐improved representation of battery degradation is possible at modest computational cost, allowing better decisions and higher profits.

“…Wind turbines and solar farm dynamic models have been developed and used in power system stability analyses in References 1‐4 to guarantee the power systems' stability during the small‐signal disturbances and load deviations. However, the unique nature of the battery energy storage system (BESS) in both active and reactive power injection/absorption into the power system highlights BESSs promising role in future power grids in both transmission 5‐7 and distribution levels, 8‐11 especially in the presence of renewables such as wind and solar farms. In general, small‐time constants, fast response, and high energy density create a large spectrum of potential applications for BESSs in power systems 12,13 .…”

Unmanaged renewables integration into the power system will raise the possibility of small‐signal instability due to higher load deviations in the transmission lines. In power grids with a higher penetration level of the renewables, the load deviation can cause interarea oscillation in the grid. Meanwhile, large‐scale battery energy storage systems are promising solutions to enhance power system stability by smoothening the load profile and their fast response. To damp the interarea oscillations without compromising the voltage stability, we need to consider the battery's dynamic model in d−q axis. The battery's dynamic model in d−q axis allows us to integrate the battery into the power system and simulate both the battery's active and reactive power injection/absorption. In this paper, we model the battery energy storage on d−q axis. Then, the battery model is augmented into the two‐area four‐machine power system. An optimum hybrid controller using linear quadratic regulator techniques is designed to damp generators' frequency deviations. The results show that the interarea oscillations are damped without losing the voltage stability of the system.
