| 摘要: |
| 随着分布式光伏的大量并网，电压越限成为限制其大量接入的重要因素。针对光伏接入引起电压越限的情况，研究了多种调压措施对配电网光伏接纳能力的影响。首先，从电压不越限、潮流不过载等约束条件出发，建立了分布式光伏消纳模型。其次，分析了加入调压措施对分布式光伏消纳能力的影响。最后，采用试探法求解了不加调压措施前和加入调压措施后光伏的最大准入容量。以IEEE33节点配电系统为仿真算例，分析了限制各个节点光伏容量增加的原因。仿真结果表明，考虑调压措施可以有效地提高分布式光伏的消纳能力，避免电压越限的发生。 |

| Abstract: |
| With more and more photovoltaic connected to the grid, the voltage violation has become an important factor in restricting a large number of PV in distributed network. In order to solve this phenomenon, this paper studies the influence of many voltage regulation measures on distribution network PV accommodating capability. Firstly, considering constraint conditions of voltage not violation and power flow under load, it establishes a distributed PV accommodation model. Secondly, it analyzes the effect of PV accommodation after adding voltage regulation measures. Finally, it calculates the maximum grid-connected capacities before and after considering voltage regulation measures by using heuristics method. The IEEE33 bus distribution system is simulated and the restricted factors to the increase of PV capacities of each node is analyzed. The result shows that considering voltage regulation measures effectively improves the photovoltaic accommodation ability and avoids node voltage violation.
