针对多因素下多种备用资源的优化配置问题,提出基于外部成本内置法的备用市场竞价模型。以需求响应为机会成本,同时考虑容量事故的不确定性,采用风险管理方法建立发电侧备用需求曲线,实现需求侧与发电侧两类备用资源的协调。量化分析发电侧备用可靠性与碳排放因素的边际外部成本,并将该成本内置到发电侧备用的内部成本报价中,以所得边际综合成本作为竞价依据,进一步实现了发电侧备用资源的内部协调。最后,通过供需理论得到备用最优点。算例仿真结果证明所提方法能够从社会角度实现备用资源的优化配置,具有可靠性与碳减排激励作用。
Aiming at the optimal allocation of multiple spare resources under multiple factors, a reserve market bidding model based on the external cost built-in method was proposed. Taking the demand response as the opportunity cost and taking into account the uncertainty of the capacity accident, the risk management method is adopted to establish the generator-side standby demand curve, and the two types of standby resources on the demand side and the power generation side are coordinated. Quantitatively analyze the marginal external costs of the reserve-side reliability and carbon emission factors on the power generation side, and build this cost into the reserve-based internal cost quotations on the power generation side. Using the resulting marginal comprehensive cost as a basis for bidding, the internal coordination of standby resources in the power generation side is further realized. . Finally, the best advantage of backup is provided through supply and demand theory. The example simulation results show that the proposed method can optimize the allocation of spare resources from a social perspective, and has the effect of reliability and carbon emission reduction.
