与市场机制相协调的发电交易与调度的节能减排方法

The Method About Energy Saving and Emission Reduction of Power Generation Transaction Dispatch Conformed to Market Mechanism

提出了一种与电力市场机制相协调的发电交易和调度的节能减排调度方法。该方法通过容量合同交易实现机组的高低能耗置换的同时,也给高能耗机组提供了回收成本的可能性;以变动成本表征能耗大小,通过变动成本报价与污染物排放确定机组的竞价上网排序;通过合理的结算规则使机组自发地参与容量合同交易和节能发电调度,实现电力节能减排以及资源优化配置的目标。工程应用模拟分析表明,在同一时段内,该方法减少了发电能耗与污染物排放(特别是SO2和CO2排放),同时稳定了发电侧的上网电价,具有很强的实用价值。

A method about energy saving and emission reduction of power generation transaction dispatch that conforms to the market mechanism is presented in this paper. Through capacity contract trade, this method not only achieves exchange for energy consumption, but also provides the possibility of cost recovery for low efficiency unit. Pricing of variant-cost reflects the energy consumption and the power generation amount is decided by the comprehensive compositor of energy consumption and emission. This method makes the units to participate in energy saving dispatching and capacity contract transaction spontaneously through reasonable settlement method, so as to realize the goal of grid energy saving and emission reduction at the same time. Simulation analysis verifies that the method not only reduces energy consumption of generation and contamination-emission （especially SO2 and CO2 emission） , but also stabilizes pool purchase price. Therefore this model possesses high practical value.
