摘要
分布式发电的并网位置对配电网的电压稳定有着重要的影响,基于连续潮流法和模态分析并以安全电压范围内减少无功损耗为原则,研究分布式发电不同并网位置对电压变化的影响。连续潮流法可快速准确地找出电压崩溃点,模态分析能确定系统稳定的薄弱区域及相应元件的参与程度,且通过结合连续潮流法和模态分析来选择分布式发电的最佳并网位置,由IEEE 33节点系统测试结果表明新算法确定分布式发电的并网位置的可行性。
The layout of distributed generation has important influence upon voltage stability in distribution network. Based on continuation power flow method and modal analysis method, and taking reducing the reactive losses within the scope of the safety voltage as the principle, the influence upon voltage change from the different position of distributed generation is researched. The continuation power flow method can accurately and quickly obtain voltage collapse point, and the modal analysis can accurately find out the weak area of the system and the participation degree of the corresponding components. And the optimum interconnection position of distributed generation is chosen based on continuation power flow method and modal analysis. IEEE 33 node system test results show that the new algorithm of the layout of distributed generation is feasible.
