Concentrating solar power (CSP) has been advocated as a promising technology to mitigate the uncertainty in variable renewables generation due to its thermal storage capability. In deregulated markets, however, it remains an open question as to how to identify different CSP plants’ contributions to uncertainty mitigation, and incentivize their participation in joint offering with variable renewable generation. In this article, we propose a profit-sharing mechanism to incentivize the joint offering of CSP and wind power aggregation. The joint offering strategy is formulated as a two-stage stochastic optimization model, aimed at maximizing the day-ahead market revenues, considering real-time imbalance settlement. A Nash bargaining (NB)-based market mechanism is designed to allocate the surplus from the joint offering. In contrast to symmetric NB with equal bargaining power (BP), we develop a novel BP evaluation method by precisely quantifying the market contributions of different producers in the joint offering. To preserve the autonomy of each producer, a decentralized solution framework is presented. Case studies show that the joint offering of wind power and CSP aggregation can effectively mitigate real-time imbalance. The proposed profit-sharing mechanism can identify market participants’ contributions in both the day-ahead and balancing markets.

风电场聚集和太阳能集中的利益共享机制

聚光太阳能（CSP）由于其蓄热能力而被认为是缓解可变可再生能源发电不确定性的一种有前途的技术。但是，在放松管制的市场中，如何确定不同的CSP工厂对降低不确定性的贡献，以及如何激励他们参与可变可变发电的联合提供，仍然是一个悬而未决的问题。在本文中，我们提出了一种利润分享机制，以激励CSP和风力发电联合提供。联合提供策略被表述为两阶段随机优化模型，旨在考虑实时不平衡结算以最大化日间市场收入。基于纳什议价（NB）的市场机制旨在分配联合发行的盈余。与具有相同议价能力（BP）的对称NB相比，我们通过精确量化联合生产中不同生产商的市场贡献来开发一种新颖的BP评估方法。为了保持每个生产者的自主权，提出了一个分散的解决方案框架。案例研究表明，联合提供风能和CSP聚合可以有效缓解实时不平衡。拟议的利润分享机制可以确定市场参与者在日前市场和平衡市场中的贡献。案例研究表明，联合提供风能和CSP聚合可以有效缓解实时不平衡。拟议的利润分享机制可以确定市场参与者在日前市场和平衡市场中的贡献。案例研究表明，联合提供风能和CSP聚合可以有效缓解实时不平衡。拟议的利润分享机制可以确定市场参与者在日前市场和平衡市场中的贡献。
