《Energy Consumption Optimization of Lithium-ion Battery Storage Power Station》

Energy consumption estimation and optimization of energy storage power stations is the key technology to improve the energy efficiency and economy of power stations. By analyzing the working characteristics and energy consumption laws of battery modules, energy storage converters, transformers and auxiliary power systems during the operation of electrochemical energy storage power stations, the energy consumption model of energy storage units and auxiliary power consumption systems is established. Based on the load ratio, the energy consumption model of energy storage power station was established, and the application verification was carried out by 100 MW-level energy storage power station on the grid side of a certain region. The data show that the average error between the energy consumption model and the real data is 0.6%, which can effectively estimate the energy efficiency level of energy storage power station. Based on this energy consumption model, the existing power station strategy can be optimized, and the data show that the power allocation strategy based on the energy consumption model can improve the energy efficiency of energy storage power station by 0.6%-10.7% under the condition of less than 50% load ratio, and effectively improve the operation economy of the power station by reducing the energy consumption of the power station.
