考虑报价监管的动态调峰辅助服务市场竞价机制设计

Design of Dynamic Peak Regulation Ancillary Service Market Bidding Mechanism Considering Quotation Supervision

随着东北地区调峰辅助服务市场化交易的深入推进,现行调峰辅助服务市场机制的缺陷日益凸显,其中机组调峰积极性不高和调峰价格虚高的问题亟待解决。针对机组调峰积极性不高的问题,建立跟随负荷波动的浮动调峰基准以保障机组的调峰收益。同时,针对调峰价格异常的现象,通过分析机组的调峰成本以及机组利润最大化的一阶条件,推导出机组的调峰报价公式,进而制定利于市场监管的报价规则。最后,建立调峰辅助服务市场双层竞价调度模型以及市场结算方法,形成动态调峰辅助服务市场竞价机制。基于辽宁省电网实际运行数据的算例,证明该文提出的动态调峰辅助服务市场竞价机制可以有效提高机组的调峰积极性,并使市场价格合理化。

With the further advancement of market-oriented transactions of the peak regulation ancillary service in Northeast China,the shortcomings of the current peak regulation ancillary service market mechanism have become increasingly prominent.Among them,the problems of low peak regulation enthusiasm of units and the false high peak ancillary prices need to be resolved urgently.Aiming at the problem of the low peak regulation enthusiasm of units,a floating peak regulation benchmark that follows load fluctuations was established to protect the units'peak regulation revenue.At the same time,in terms of the phenomenon of abnormal peak regulation prices,the peak regulation quotation formula of units was derived by analyzing the peak regulation costs of units and the first order condition for maximizing the profit of the units,and then the quotation rules that are conducive to market supervision were formulated.Finally,the bi-level bidding scheduling model and market settlement method were established to form dynamic peak regulation ancillary service market bidding mechanism in this paper.Based on the example of actual operation data of Liaoning power grid,it is verified that the dynamic peak regulation ancillary service market bidding mechanism proposed in this paper can effectively increase the peak regulation enthusiasm of units and rationalize the market price.
