【摘要】：为了发展一种适用于我国电力市场的输电定价方法,对国外输电定价方法进行了深入研究。英国输电过网费的定价方法是对全网统一计算,没有考虑区域联络线的影响。美国PJM输电所有者内部采用邮票法分摊输电成本,没有起到引导输电布局的功能。我国有很多跨区输电线路,不同区域间的经济水平和电网结构差异也很大。因此,针对我国电网的实际特点,深入研究分区输电定价机制。将区域联络线等效为发电机或者负荷,实现区域的解耦,在区域内用英国方法计算与位置相关的费用,利用修正邮票法计算与位置无关的费用,通过潮流跟踪方法收回区域联络线等效后的费用。算例结果分析表明,所提分区输电定价方法能合理分摊输电成本,为分区定价提供了思路,可为电网规划提供指导信息。
[Abstract]:In order to develop a transmission pricing method suitable for China's electricity market, the foreign transmission pricing methods are deeply studied. The impact of regional tie-line is not taken into account. PJM transmission owners in the United States use stamp method to share transmission costs, which does not play a role in guiding the distribution of transmission. There are many transregional transmission lines in China. The economic level and network structure of different regions are also very different. Therefore, in view of the actual characteristics of China's power grid, the regional transmission pricing mechanism is studied in depth. The regional tie-line is equivalent to generator or load. In order to realize the decoupling of the region, the British method is used to calculate the location-related costs, and the modified stamp method is used to calculate the location-independent costs. The equivalent cost of the regional tie-line is recovered by the method of power flow tracking. The result of the example shows that the proposed method can apportion the transmission cost reasonably and provide a way of thinking for the district pricing. It can provide guidance information for power network planning.
