摘要
从电力系统安全运行的角度出发,利用购买碳排放权成本指标,研究了碳价波动引起碳捕集电厂出力变化的问题。根据经济学的需求价格弹性原理来反映碳价与碳捕集水平之间的关系,并引入α-超分位数理论来度量碳捕集电厂出力的不确定性,以日前节能环保为目标,构建了碳捕集电厂的电力系统日前环保调度模型。IEEE30节点系统算例表明,采用α-超分位数约束的含碳捕集系统日前环保调度,可在不同置信水平和不同碳捕集电厂碳排放量的α-超分位数约束下,获取侧重环保性或经济性的系统各时段最优调度方案。
According to the safe operation in power system, the change of carbon capture power plant output caused by the flucamtion of carbon price is researched by cost index of the purchase of carbon emission fights. The relationship between carbon price and the level of cadxm capture is reflected by using price elasticity of demand theory in economics, α-superquantile theory is introduced to quantify the uncertain output of carbon capture power plant, Taking day-ahead energyg and environment-protective as objective, the model of daily environmental protection dispatch in cadxm capture power plant integrated system is conslructeck The example on IEEE30 system show that under different confidence levels and different αuantile constraints of carbon emissions, the proposed model can achieve optimal dispatching results in each period that emphasize on environment or economy.
