| 摘 要： | 当新能源分布式发电并网后,新能源发电的随机性与分布式发电与负荷的空间关系会对电力系统的潮流、电能质量和运行可靠性造成影响。本文旨在研究将新能源发电与一个典型村镇配电网连接后,对电压、潮流和对有载调压变压器等电力设备运行的影响。并结合村镇配电网的运行特点,对分布式发电接入造成的影响进行分析,探讨了减少发电机输出约束需求的解决方案。其次,通过SIMULINK模拟了可再生发电系统(光伏阵列)与村镇配电网系统,分析了新能源分布式发电对村镇配电网的影响。

| Abstract: | After connecting distributed renewable generation to power grid,intermittent characteristic and connecting location of it will lead to effects on power flow,power quality and operation reliability.This essay aims to investigate the effects of connecting renewable generation to typical rural power network on voltage,power flows and operation of network equipment such as transformers with On-Line Tap Changers(OLTCs).After literature review of impact of increased renewable generation capacity in distributions grids,simulation of OLTC-equipped system with renewable generation(PV array)to analyse the impact of variable renewable generation in distributions grids was implemented. |
