Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a method and system for energy storage system planning. Background technique [0002] With the rapid development of the economy, the power load is increasing day by day, the existing equipment capacity of the distribution network cannot meet the demand, and the peak-valley difference of the load is gradually intensified, resulting in a decrease in the utilization rate of the distribution network equipment and an increase in investment costs. More and more high-tech and digital enterprises have put forward higher requirements for power supply reliability and power quality. [0003] At present, various impact loads, nonlinear loads and asymmetric loads may cause power quality problems in distribution networks, leading to high-order harmonics, voltage flicker, voltage drops and other problems. The frequency modulation requirements of the system are becoming more ...
