| 摘要: |
| 提出了一种评估储能支撑分布式光伏接入价值的方法，分别针对有储能和无储能接入2种情况，以适应大规模分布式光伏接入所采取的技术措施总成本最优为目标，利用年度8 760 h潮流计算和智能优化方法，优化确定2种情况下的最优技术措施组合及其相应的成本，从而通过对比2种情况下的技术措施成本构成进而进行储能价值评估。案例分析显示，储能可以减少高比例分布式光伏接入带来的电网改造成本和限电损失，但实际应用中需加以优化；现有投资成本条件下，仅考虑电量价值，储能自身尚不具备经济性；推动储能快速起步需要计及其带来的电力价值。 |

| Abstract: |
| A method for assessing the value of energy storage in supporting the large-scale integration of distributed PVs is proposed，which applies the annual 8 760-hour power-flow calculation and intelligent optimization method with the minimum total cost of all technical measures for the large-scale integration of distributed PVs as its objective to determine the optimal combination of technical measures and its relevant total cost for two conditions：with and without the energy storage. The value of energy storage is assessed by the comparison of total cost. Results of case analysis show that，the application of energy storage can reduce the cost of power network reinforcement and the power curtailment loss due to the highly proportional integration of distributed PVs，but its application to actual power grid needs to be optimized；if only its electricity value is considered，the application of energy storage does not have the economic benefit in the condition of present investment cost；its power value should be counted in for promoting its application. |
