Purpose of review This paper reviews optimization models for integrating battery energy storage systems into the unit commitment problem in the day-ahead market. Recent Findings Recent papers have proposed to use battery energy storage systems to help with load balancing, increase system resilience, and support energy reserves. Although power system
Hydrogen batteries have the highest specific energy compared to other storage systems and have a high life cycle as well. Though hydrogen batteries are environmentally friendly and have a long life cycle, it has a high initial cost. On the other hand, flow batteries are safe as they are nonflammable and demonstrated a long battery life, and it is not dependent
Unlike traditional power plants, renewable energy from solar panels or wind turbines needs storage solutions, such as BESSs to become reliable energy sources and provide power on demand [1].The lithium-ion battery, which is used as a promising component of BESS [2] that are intended to store and release energy, has a high energy density and a long energy
