摘要:

目前,新能源接入比例的持续增加,使得电网调频需求日益增长。为充分挖掘电池储能系统(BESS)在提升传统火电机组调频性能方面的应用潜力,提出一种针对长时间运行系统调频指标优化的分段式控制策略及荷电状态(SOC)维护策略。所提策略与传统差额控制策略以及机组历史综合调频性能指标k的对比分析结果显示,在全天超20 h的运行时长条件下,所提策略的综合调频性能指标依旧能达到2.0以上,明显优于火电机组单独调频的0.8以及传统差额控制策略的1.2,验证了所提控制策略的有效性,对后续的工程实践具有重要的借鉴意义。

Abstract:

At present, the increasing integration of new energy sources is leading to an increasing demand for grid frequency regulation. In order to fully explore the potential of battery energy storage system(BESS)in improving the frequency regulation performance of traditional thermal power units, a segmented control strategy and a state of charge (SOC) maintenance strategy are proposed for optimizing the frequency regulation index of long-term operating systems. The comparative analysis of the proposed strategy with the traditional differential control strategy and the historical comprehensive frequency regulation performance indicators k of the unit shows that under the condition of an operation duration of more than 20 hours throughout the day, the proposed strategy can still achieve a comprehensive frequency regulation performance indicator of 2.0 or above which is significantly better than the 0.8 for the individual frequency regulation of thermal power units and the 1.2 for the traditional differential control strategy. This verifies the effectiveness of the proposed strategy and has important reference significance for subsequent engineering practices.
