In order to assess the operation performance of second-use battery energy storage system, a comprehensive assessment method was proposed based on the analytic hierarchy process, in which the operation benefits and electrical characteristics were considered simultaneously. A quantitative assessment frame was constructed, where the amount and fluctuation of exchanging power between the active distribution network and the main grid were utilized to quantify the operation benefits and the voltage fluctuation, three-phase imbalance factor and harmonic current of grid-connection point were utilized to quantify the electrical characteristics. The weights of indices at the same level were obtained by the analytic hierarchy process and the comprehensive index value was calculated by the weighted summing of quantitative index values. 15 kW/30 (kW·h) prototype of second-use battery energy storage system was developed based on the dynamic reconstructing strategy and applied to the ten-day on-line test, from which the field data were obtained and used to validate the effectiveness of the proposed method. The case study results indicated that the second-use battery energy storage system had satisfactory electrical characteristics and could decrease the exchanging power, smooth the power fluctuation and improve the renewable energy accommodation.
