考虑碳交易的风光储场站参与电力现货市场报价策略与调控方法

Bidding Strategy and Regulation Method for the Unified Wind/Photovoltaic/Energy Storage Power Stations in Electricity Spot Market Considering Carbon Trading

随着我国“双碳”目标的提出,大规模风光储场站的建设已经成为了电力减排的有效途径。然而,风光储之间的耦合性难以刻画,碳交易对风光储出力的影响不明确,如何合理报量报价来实现现货市场收益最大等问题已经成为制约大规模风光储发展的关键问题。为此,该文首先设计考虑碳交易影响的电力现货市场机制;然后,基于风光储之间的耦合效应,提出场站的最优报价策略与协同调控方法,并考虑风光出力不确定性,构建风光储场站参与报量报价的双层模型,以实现其收益的最大化;最后,利用IEEE-14节点系统的算例证明方法的有效性。算例结果表明该文框架与模型能够优化风光储场站报价,丰富储能套利手段,在提升场站收益的同时降低系统碳排放。

With the proposal of the"Dual Carbon"target,the construction of the large-scale wind/photovoltaic/energy storage power station(WPS)has become an effective way to reduce carbon emissions.However,the coupling among wind,photovoltaic and energy storage is difficult to describe,and the impact of carbon trading on the output of WPS is unclear.Therefore,how to design a reasonable bidding strategy for maximum interests in the electricity spot market has become a key issue in the development of large-scale WPS.First,in order to solve the aforementioned problems,the electricity spot market mechanism is designed considering the impact of carbon trading.Secondly,under the coupling effects in WPS,an optimal bidding strategy and a co-regulation method of WPS are proposed.To realize the maximization of WPS’s interests,a bi-level bidding model is constructed,where the uncertainty of renewable power is considered.Finally,case studies based on the IEEE 14-bus system indicate the efficiency of the proposed methods.The results show that the model in this paper can optimize the WPS’s bidding strategies and broaden the arbitrage behaviors of energy storage.In addition,the model is also conducive to boosting WPS power station’s interests and reducing the system carbon emissions.
