【 摘 要 】

The future measurement systems will be multiple and incomplete collect for measurements. The proposed method could not fully utilize real-time measurements. The estimation precision of non-measured loads will be lower. The distribution analysis and calculation precision will be lower too. So this paper establishes the no-measured loads estimation model with all real-time measures. The proposed algorithm is developed based on Monte Carlo simulation technique. The power flow is carried out for simulated multi-group no-measured loads values. Then power results that are more approach real-time measures are marked. The marked simulated multi-group no-measured loads values are used to calculation expectations of no-measured loads. The no-measured wind outputs are accurately estimation by branch power direction judgment. The compared results of different algorithm verify the accuracy and practicability of the proposed algorithm.
