摘要:

为提升虚拟电厂(virtual power plant,VPP)参与电力市场的经济性与调控协调性,提出一种基于分层分区调控的虚拟电厂市场多时间尺度竞价策略。首先,定义虚拟机组作为调度与交易统一建模单元,依据电网拓扑结构与过载风险构建分区聚合策略,进一步构建其外特性表征模型以反映虚拟电厂可调节能力。其次,建立涵盖日前与实时市场的多时间尺度竞价模型,并利用库恩-塔克(Karush-Kuhn-Tucker,KKT)条件将其转化为单层优化问题以降低求解复杂度。最后,通过算例验证所提模型的有效性。结果表明,该策略可在保障网络安全与隐私保护的基础上,有效降低建模维度;可实现VPP在多时间尺度市场中的协调竞价,与采用固定报价和仅考虑日前市场相比,VPP收益分别提升了15.8%和17.2%,增强了VPP的市场适应能力与收益水平。

Abstract:

To enhance the economic efficiency and coordination capability of virtual power plant (VPP) in electricity markets, this paper proposes a multi-timescale bidding strategy based on hierarchical and zonal regulation. Firstly, virtual power units are defined as unified modeling units for dispatch and trading. A zonal aggregation strategy is developed based on grid topology and overload risk, and external characteristic models of virtual power units are constructed to represent the regulation capability of VPP. Secondly, a multi-timescale bidding model covering both day-ahead and real-time markets is established, and the bi-level optimization problem is transformed into a single-level model via Karush-Kuhn-Tucker (KKT) conditions to reduce computational complexity. Finally, case studies are conducted to validate the effectiveness of the proposed model. Results demonstrate that the proposed strategy can effectively reduce modeling complexity while ensuring network security and privacy protection. It enables VPP to coordinate bidding in multi-time scale markets, with VPP revenue increasing by 15.8% and 17.2% compared to fixed bidding and the day-ahead market, respectively, thus enhancing its market adaptability and profitability.
