Abstract: Network loss caused by the power generation right trade and impact on the system based on DC power flow equation are calculated. The method takes into account each power flow state, and better conforms to the practical situation of generation right trade. By analyzing the mechanism and process of generation right trade, a trading power allocation curve is fitted using cubic spline interpolation. This avoids the drawback of average allocation of trading power within the trading hours under the daily generation right trade mode. The curve can be adjusted by trading power, and can replace the average allocation method. The proposed method is verified by an IEEE13 node example.

Key words: cubic spline interpolation, network loss, short-term generation right trade, trading power
