| 摘要: |
| 目前光伏运维周期主要由人工经验确定，成本过高，不利于光伏产业的发展，为此，提出一种考虑分布式光伏系统典型场景的最优运维周期确定方法。建立分布式光伏2种典型应用场景数学模型；以光伏可靠性模型以及光伏组件积灰模型为基础，建立运维周期模型；利用蒙特卡洛法计算不同运维周期下由发电损失成本及运维成本组成的运维总成本的概率分布。通过不同算例的模拟结果平均值确定最优运维周期，验证了所提方法的有效性和合理性。 |

| Abstract: |
| The current PV(PhotoVoltaic) operation and maintenance cycles are mainly determined by human experience, the cost is too high, and it is not conducive to the development of PV industry, for which, a determination method of optimal operation and maintenance cycles is proposed considering the typical sce-narios of distributed PV system. The mathematic models of two typical application scenarios of distributed PV are established. Based on the models of PV reliability model and PV module dust accumulation model, an operation and maintenance cycle model is established. The Monte Carlo method is used to calculate the probability distribution of total operation and maintenance cost composed by power generation loss cost and operation and maintenance cost under different operation and maintenance cycles. The optimal operation and maintenance cycles are determined by the average values of simulative results of different examples, verifying the validity and rationality of the proposed method. |
