考虑调频绩效机制下储能在多市场中的最优投标策略研究

Optimal Bidding Strategy of Energy Storage in Power Market with Performance-Based Regulation Mechanism

辅助服务对于保证电力系统的安全稳定运行至关重要。随着具有间歇性和波动性的可再生能源的比例不断增大,电网的调峰调频需求和压力不断增加。储能具有快速响应调节能力,是优质的调频资源。基于绩效的调频市场机制可以为储能提供经济激励,合理补偿其成本,调动储能提供调频的积极性。建立了在基于绩效的调频市场机制下储能的日前多市场最优投标决策模型。该模型可以指导储能优化资源配置,在能量与辅助服务市场收益之间进行权衡,实现利润的最大化;还可以作为估计储能收益潜力的工具,进而引导储能的投资决策。最后通过算例分析验证了所建模型的有效性。

Auxiliary services are essential to the reliable operation of power systems. As the penetration of：intermittent and variable renewable energy increases, the requirements of reserve and regulation in power grid rise correspondingly. Energy storage is a high-quality regulation resourcs, because of its fast ramping and responding capability. Performance- based regulation mechanism can provide economic incentive for energy storage and reasonable compensation： for its cost, which can arouse the enthusiasm of energy storage. This paper constructs the optimal bidding strategy model for energy storage in current power market with considering performance-based regulation mechanism, which can guide the optimal resource allocation of energy storage, and help make a trade-off for energy storage between revenues from energy markets and auxiliary service markets to achieve the maximization of profits. The proposed model can also help estimate the profit potential of energy Storage, and in turn help its investment decision. The validity of the proposed model is verified by example analysis.
