考虑碳排放成本的备用市场竞价模型

A reserve market bidding model considering carbon emission costs

以电力低碳化发展趋势为背景,以备用资源优化配置为目的,提出了能够体现碳减排因素的备用市场竞价模型。该模型建立机组备用需求曲线,以考虑容量事故随机性特性和实现多种备用资源的协调配置;应用外部性内在化理论,将边际碳排放成本内置到机组备用报价中,以得到的边际综合成本作为竞价依据,从而反映机组碳排放特性的影响。最后采用供给与需求理论方法获得备用决策最优点。对该竞价方法与传统竞价方法进行了比较,比较结果证明该方法可以找到最优的备用配置点,同时具有碳减排激励作用。该方法兼顾了备用服务的市场化运营与碳减排要求,算例结果也验证了这一点。

On the background of low carbon trends of electric power sector, a reserve market bidding model considering camon emission reduction is presented. A reserve demand curve is built firstly, which can consider the uncertainty of contingencies and coordinate the allocation of multiple reserve resources. Internalization of externalities theory is applied and according to which the marginal carbon emissions cost is internalized into the bids to get the marginal overall cost to reflect the affects of carbon emission. Last, supply and demand theory is used to obtain the decision point. The differences of the presented method is compared with the traditional method, results show that the former can realize optimal allocation of reserve resources, and also has incentives to the reduction of carbon emission. Case study demonstrates the presented method can balance both marketing operation of reserve service and carbon emission reduction requirements.
