就日前电力市场的竞价机制进行讨论 ,指出了当前普遍采用的分时竞价机制存在的问题。在此基础上介绍了分段竞价机制 ,并重点以包含 34台火电机组和 1 7台水电机组的实际电力系统为例 ,对这两种竞价机制进行了详细比较。计算结果说明了采用分段竞价模式的电力市场不仅符合电力运行的特点 ,使系统发电成本降低 ,而且减少了市场购电费用 ,具有更高的市场效率
Discuss the bidding mechanism in the electricity market recently, and point out the problems existing in the current time-sharing bidding mechanism. On the basis of this, the sub-bidding mechanism is introduced, and the actual power system including 34 thermal power units and 17 hydropower units is emphatically taken as an example to compare the two bidding mechanisms in detail. The calculation results show that the electricity market adopting staged bidding model not only meets the characteristics of power operation, but also reduces the cost of system power generation, reduces the electricity purchase cost in the market, and has higher market efficiency
