基于功率矩的小容量分布式电源并网选址研究

摘要

针对在配电网馈线末端接入小容量分布式电源（DG）来改善电压水平的情形，提出了一种基于功率矩的小容量DG并网选址方法，并给出了DG选址的判据。该判据可以在改善电压水平前提下，充分地降低线路损耗，发挥DG的最大效益。通过实际算例分析与仿真，验证了该方法的可行性。%Aiming at the situation of improving voltage level by small capacity distributed generation （DG） connected to distribution network feedback line end, this paper raised a kind of small capacity DG siting method based on power torque, giving the criterion of DG siting. On the basis of improving voltage level, the criterion can fully reduce circuit losses to give play to max efficiency of DG. Via actual algorithm analysis and simulation, the feasibility of the method was verified.
