摘要
碳捕集电厂与风电协调配合是实现电力系统低碳化的重要手段,由于碳捕集电厂能耗高且风电存在反调峰特性导致负荷高峰时段二者存在低碳配合问题。针对上述问题,首先,在源侧引入碳捕集电厂综合灵活运行方式,在荷侧考虑需求响应,分别论述源荷两侧的低碳机理及其局限性,并探讨两种手段低碳特性互补的调度优势,由此给出源荷互补的电力系统低碳实现机制;其次,在考虑系统不确定性的前提下,构建以电力系统综合成本最优为目标的低碳经济调度模型;最后,在含碳捕集电厂的改进IEEE-39节点系统中进行仿真验证,结果证明该文所提调度方法能够有效结合源荷两侧资源进行优化,提高系统风电消纳能力与运行效益的同时实现低碳排放的目标。
The coordination of carbon capture power plant and wind power is an important means to achieve low-carbon power system,but due to the high energy consumption of carbon capture power plants and the anti peak regulation characteristics of wind power,there are contradictions in the low-carbon coordination of the two in the peak load period.In view of the above problems,firstly,the integrated flexible operation mode of carbon capture power plant was introduced in the power supply side,and the demand response was considered in the load side.The low-carbon mechanism and its limitations on both sides of the source and load were analyzed respectively,and the dispatching advantages of the two methods with complementary low-carbon characteristics were discussed.Thus,the low-carbon realization mechanism of power system with complementary of source side and load side was proposed.Secondly,under the premise of considering the uncertainty of the system,a low-carbon economic dispatch model was constructed to optimize the comprehensive cost of power system.Finally,the simulation was carried out in the modified IEEE-39 node power system with carbon capture power plant.The results showed that the proposed scheduling method could effectively combine the resources on both sides of the power supply and load to improve the wind power consumption capacity and operation benefit of the system,and achieve the goal of low carbon emissions.
