摘要: |
针对多个三相不平衡配电网络,在不同位置接入分布式光伏,运用OpenDSS软件计算了分布式光伏接入配网后节点电压偏差及谐波电压畸变率。根据ANSI C84.1-2006稳态电压标准以及IEEE519-1992谐波标准对电压偏差和谐波电压畸变率进行约束,得出不同位置下稳态电压偏差和谐波约束下分布式光伏的最大渗透率,同时分析了线路调压器及光伏接入点短路容量与光伏渗透率的关系。研究结果表明,光伏渗透率与具体配电网的拓扑结构和线路参数相关,光伏接入点越靠近馈线首端,渗透率越大。同时考虑电压偏差和谐波约束下光伏渗透率至少能达到20%,并且使线路调压器与其下游接入的光伏发电功率协调配合也可显著提高光伏的渗透率。 |

Abstract: |
This paper interconnects distributed photovoltaic with several PV location scenarios for several unbalanced distribution system, and calculates the steady state voltage and voltage harmonic distortion with power flow program. Various levels of photovoltaic penetration are presented under the voltage constraints in the ANSI C84.1-2006 standard and the voltage harmonic distortion constraints in the IEEE519-1992 standard with several PV location scenarios. And with the simulation results of different output and different location scenarios of PV, the relationship between SVR and short circuit capacity and photovoltaic penetration is analyzed. The result of simulation shows that the penetration of photovoltaic is related with the line parameters of actual system. The closer the location of photovoltaic to the feeder source, the larger the penetration will be. For the cases considering the voltage and harmonic limits simulated, maximum photovoltaic penetration will be at least 20% of peak load, and with the coordination between SVR and the downstream PV system, the penetration of PV will be increased significantly. |
