| 摘要: |
| 根据典型日负荷曲线综合分析了配电网中蓄电池储能系统（BESS）在减少电网的扩建容量、削峰填谷节省总网损成本、低储高发套利、提高电网可靠性效益和减少新能源并网所需备用容量5个方面的经济价值。考虑了蓄电池储能系统的投资成本和运行维护成本，建立以年净收益为目标函数的蓄电池储能系统的最优化价值评估模型，并采用结合混合罚函数的粒子群优化算法进行求解，对蓄电池储能系统的价值进行评估。算例分析表明，目前蓄电池单位造价偏高，其经济性尚欠佳。 |

| Abstract: |
| The economic value of BESS（Battery Energy Storage System） in distribution network are comprehen-sively analyzed based on the typical daily load curve in five aspects：decrease of grid expansion capacity， reduction of total net loss cost by peak load shifting，arbitrage of energy storage，increase of grid reliability benefit，and reduction of capacity reserve for grid-connection of renewable energy resource. The optimal value assessment model of BESS，which considers the investment and maintenance costs and takes the annual net income as its objective，is established and solved by the particle swarm optimization algorithm combined with the multi-SUMT function. Case analysis shows that，due to the unit cost of battery is high at present，the economy of BESS is poor. |
