    摘要:

    针对省级控制区在电网调峰或事故处置等特殊时段存在备用不足的问题,提出省级控制区灵活组合控制的架构和策略。区域电网调控中心按照相邻区域备用共享等原则统筹决策,灵活选择省级控制区参与联合控制。首先基于现有各省级控制区边界模型和区域控制偏差(ACE)计算模式,区域电网自动发电控制计算各子控制区ACE后通过叠加快速得到组合控制区的ACE。然后结合省调实时上送的备用等信息,并考虑最低预留备用、频率偏差系数、实际可调等因素对组合控制区的ACE进行优化分配,经过省间(内)断面安全校验后下发给省级控制区执行。实现了打破省间壁垒实现控制区间备用的实时共享和事故下的紧急支援,减少控制区间的反向无谓调节。通过实际运行验证了控制策略的有效性。

    Abstract:

    To solve the problem of inadequate reserve of provincial control areas during special periods such as peak load regulation or accident disposal, the structure and strategy of flexible combination control for provincial areas is proposed. Regional power grid dispatch center flexibly selects provincial control areas to participate in joint control according to the principles such as reserve sharing in adjacent areas. Firstly, based on the existing boundary model of provincial control areas and area control error(ACE)calculation mode, automatic generation control(AGC)in regional power grid calculates the ACE of each sub-control area and then quickly obtain the ACE of the combined control area by superposition. Secondly, based on the uploaded information such as real-time reserve of provincial grid and considering factors of minimum reserve, frequency deviation coefficient and actual adjustable reserve, ACE of the combined control areas is distributed optimizedly to provincial grids for execution after grid security check of provincial(inter-provincial)sections. The goal of breaking the provincial barriers for reserve sharing and emergency support in case of accidents is achieved while reducing the unnecessary reverse regulation of control areas. The effectiveness of the control strategy is verified through the actual operation.
