摘要:
为提升高比例新能源电力系统备用充裕性和实现大规模新能源高效消纳,将备用资源来源拓展至源网荷储,从调节方向、参与方式等方面量化源网荷储灵活调节资源可提供的运行备用水平。进而,根据“常规时段同步机组承担、特殊时段多类型资源分摊”的调控思路,提出了源网荷储协调参与的运行备用容量分配策略,构建了纳入多类型异质资源的备用分布优化模型,实现各类型备用资源在“全网-同类资源-机组/场站”的逐级精细化分配。基于某省级电网开展算例测试,与现有运行备用分配准则进行比较,验证了所提策略的有效性。

Abstract:
To improve the reserve adequacy for high percentage of new energy power system and realize efficient consumption of large-scale new energy, the reserve resources are expanded to source-network-load-storage resources, and the operating reserve level provided by the source-network-load-storage flexible regulation resources is quantified in terms of the regulating direction, participation mode, et al. Furthermore, based on the regulation idea of “synchronous unit undertaking in normal periods and multi-type resource apportioning in special periods”,the operating reserve capacity allocation strategy involving coordinated participation of source-network-load-storage resources is proposed and a reserve distribution optimization model incorporating multiple types of heterogeneous resources is constructed, which realizes the level-by-level fine allocation of various reserve resources in the “whole network-similar resources-units/stations”. Based on the example of a provincial power grid for case study and analysis, the effectiveness of the proposed strategy is verified by comparing it with the existing operating reserve allocation criteria.
Key words:  operating reserve  source-network-load-storage  allocation strategy  reserve optimization  new energy accommodation
