摘要
配电网中接入分布式光伏电源会带来诸多不利影响,研究配电网分布式光伏的消纳能力问题对维持配电网的安全运行至关重要。文章研究了分布式光伏电源接入对配电网电能质量、短路容量及网损的影响,以分布式光伏电源接入量最大、网损最小为目标函数,以电压偏差、电压波动及短路容量为约束条件,建立了分布式光伏消纳能力评估模型。根据所建模型特点,提出了一种改进的花授粉优化算法(Flower Pollination Algorithm,FPA),并对IEEE33节点系统及实际配电网进行求解。最后验证了所建模型的正确性及算法的有效性。
The interconnection of distributed photovoltaic(PV)power may have a number of adverse effects on traditional distribution network.It is critical of researching on integration capacity of distribution network to maintain the safe operation of distribution network.This paper studies the effects of distributed PV on power quality,short-circuit capacity of distribution network and network loss.Then,under the target of maximizing the PV integration capacity and minimizing the power losses,and the constraints of the voltage deviation,voltage fluctuation and short-circuit capacity,a distributed PV capacity evaluation model is established.At the same time,an improved flower pollination algorithm is proposed to solve the IEEE 33-node system and the actual distribution network system according to its characteristics.The results are compared with other optimization algorithms,demonstrating the validity of the propose model and the effectiveness of the algorithm.Further calculation results show that the photovoltaic inverter in leading phase operation can effectively improve the PV integration capacity.
