Against the backdrop of the rapid development of the global new energy industry

energy storage systems have become crucial for maintaining the stable operation of power systems. Their energy conversion efficiency is directly related to energy utilization benefits

while the accuracy of high-voltage fee-controlled metering affects the fairness of electricity transactions. This paper focuses on the correlation mechanism between the energy conversion efficiency of energy storage systems and the cumulative error of high-voltage fee-controlled metering. By analyzing the research status of energy storage systems and the cumulative error of high-voltage fee-controlled metering as well as their relevant influence mechanisms

a quantitative evaluation model is constructed through theoretical derivation to clarify the quantitative relationship between the two. This study provides theoretical support for power enterprises to optimize the operation and maintenance of energy storage systems and improve metering accuracy

and also offers references for the coordinated development of the energy storage and metering industries.
