摘要/Abstract

摘要：

煤电行业二氧化碳排放量占比最多，首先被纳入了全国性碳市场，而碳排放成本又对煤电现货市场结算电价造成一定程度的影响。基于此，构建了现货市场下不考虑碳排放成本的煤电机组竞价调度模型，并进行了模拟分析；继而构建了考虑碳排放成本的煤电机组竞价模型；再以广东省为例，模拟了煤电机组在“有无风光出力”“不同碳市场”情景下煤电机组现货市场报价及出清情况的变化。结果显示，随着碳市场的逐步完善，碳价和配额总量进一步收紧，煤电机组报价逐渐升高，现货市场结算电价也随之提高，夏季有风有光情景下轻度、中度、重度碳市场的平均出清电价分别为0.1607元/(kW·h)、0.1863元/(kW·h)、0.2461元/(kW·h)，较未引入碳市场时分别增加了0.18%、16.14%、53.41%。

Abstract:

The coal power industry has generated the largest proportion of carbon dioxide emissions, which makes itself the first entity to be introduced into the national carbon market, while carbon emission costs will also have certain impacts on the settlement of electricity prices in the coal power spot market. Hence, this paper constructs a bidding scheduling model for coal-fired power units in the spot market and conducts simulation analysis with and without considering the cost of carbon emissions respectively. Finally by taking the power market of Guangdong Province as the study case, the changes in the spot market bidding and clearance of coal power units are simulated under the scenarios of so-called "with vs. without wind power output" and "different carbon markets". The results show that with the gradual improvement of the carbon market, the price and total quota amount of carbon are further tightened, and the bid price of coal-fired power units increases gradually, so does the settlement electricity price in the spot market. The average electricity clearing prices in the light, moderate, and heavy carbon markets in the summer with wind and light are 0.1607 CNY/(kW·h), 0.1863 CNY/(kW·h), and 0.2461 CNY/(kW·h), respectively, up by 0.18%, 16.14%, and 53.41% compared to the scenarios when the carbon market is not introduced.
