节点功率分配原则对此研究

Comparison of sharing principle of node power

对节点复功率分配原则和原有的比例分配原则进行了深入的对比分析,推导出了原有的按比例分配原则成立的充分必要条件,讨论了复功率分配原则可能出现的反向潮流问题,对2种节点功率分配原则进行了相对误差分析。分析表明原有的比例分配原则仅在某些特定条件下成立,按其进行潮流追踪可能会造成较大误差,潮流追踪应当以节点复功率分配原则为基础。为利用潮流追踪算法解决电力市场中的输电费用和网损分配等问题提供了理论依据。

An in-depth contrast to complex power sharing principle and original proportional sharing principle of node power was carried on, the sufficient and necessary conditions for original proportional sharing principle were theoretically proved. Then, the possible counter-flow was discussed and the error between two kinds of node power sharing principles was analyzed. It is proved that original proportional sharing principle is correct only under some specified conditions, based on which great error may be caused, thus power flow tracing should base on complex power sharing principle. The study provides the theoretical foundation to solve the allocation problems of transmission fees and transmission loss in electricity market.
