| 摘 要： | 考虑电力系统调频效果和储能容量，提出一种储能参与电网一次调频的出力策略。通过超短期负荷预测曲线得到调频需求，提出了基于双层模糊控制的动态荷电状态(SOC)基准储能容量恢复策略，并给出了储能电池参与一次调频的效果评价指标与储能SOC健康度评价指标。最后，以典型区域电网为例，对所提策略在2种典型工况下进行仿真分析并与常规控制策略比较。结果表明，所提策略能够有效改善调频效果和储能SOC健康状态。

| Abstract: | Considering the frequency regulation effect and energy storage capacity of power system, an output strategy of energy storage participating in primary frequency regulation of power grid is proposed. The frequency regulation demand is obtained by the ultra-short-term load forecasting curve, and a benchmark energy storage capacity recovery strategy of dynamic state-of-charge(SOC)based on bi-level fuzzy control is proposed. Moreover, the evaluation indices including the effect of energy storage battery participating in the primary frequency regulation and the health of energy storage SOC are given. Finally, taking the typical regional power grid as an example, the proposed strategy is simulated and analyzed in two typical conditions and compared with the conventional control strategy. The results show that the proposed strategy can effectively improve the frequency regulation effect and the health of energy storage SOC. |
