Overview Battery energy storage systems (BESS) use rechargeable battery technology, normally lithium ion (Li-ion) to store energy. The energy is stored in chemical form and converted into electricity to meet electrical demand.
The BESS has a rated power of 20 MW and a rated capacity of 40 MWh. It is assumed that the initial state of charge (SOC) of the storage power plant is 0.4, with upper and lower operating SOC limits of 0.95 and 0.05, respectively. The charging and discharging efficiency of the storage power plant is uniformly set at 0.95.
The BESS can bid 30 MW and 119 MWh of its capacity directly into the market for energy arbitrage, while the rest is withheld for maintaining grid frequency during unexpected outages until other, slower generators can be brought online (AEMO 2018).
In the quest for a resilient and efficient power grid, Battery Energy Storage Systems (BESS) have emerged as a transformative solution. This technical article explores the diverse applications of BESS within the grid, highlighting the critical technical considerations that enable these systems to enhance overall grid performance and reliability.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
