Optimizing Operations of Sodium Sulfur (NAS) Large-scale Battery Storage

Battery storage is critical for the continued growth of renewable energy sources (RES) deployment. as it mitigates RE systems intermittency. Optimal energy management and operations of the storage is important to ensure profitable utilization of the battery assets. This paper presents the optimal operations profile of sodium sulfur (NAS) battery storage (BESS), coupled with a 13 MW PV Plant in Dubai, considering different operational modes and variable wholesale tariff rates. The aim is to increase the profit by controlling BESS based on different tariff rates and solar plant production. A linear optimization algorithm is developed and applied using MATLAB. The results show the profit of the system has increased by 0.27% while the grid penalties were not avoided.
