摘要

The computational complexity of existing planning method for HV distribution network is big, which is only for off-line analysis and can not be applied to online calculation. With the change of system operating condition, the economy and stability of HV distribution network still have great improvement space. In order to improve the calculation speed of HV distribution network planning, and make it can be applied to on-line calculation of actual system, this paper presents the local power plant output redistribution scheme based on the sensitivity analysis, and verifies the effectiveness of the proposed method by a practical system. According to this analysis, it shows that the reasonable adjustment of the local power plant output distribution can effectively reduce the network loss index, voltage deviation and voltage stability L index, and improve the voltage stability, power quality and economy of HV distribution network.
