摘要
针对目前自动发电控制AGC(AutomaticGenerationControl)领域平衡控制较难实现的问题,提出了基于日电量平衡的自动发电控制策略。首先,设定功率偏差、电量百分数以及速度权重因子,在满足调节目标值区域控制偏差ACE(AreaControlError)的基础上,使投入AGC控制的发电机组实际运行总发电量与计划总电量接近平衡,保持实际的每日24h有功负荷曲线与计划负荷曲线尽量一致。利用速度权重因子修正发电量,在满足响应速度的同时实施动态优化调节。利用江苏电网实际运行数据进行了仿真,结果表明,该策略能够很好地完成ACE调节目标,达到了实现日电量平衡控制的理想效果。
Aiming at balance control difficulty,an AGC（Automatic Generation Control） strategy based on the balance of daily electric energy is put forward. After the power error,power charge percentage and speed weighting factor are set,the actual total generated energy controlled by automatic generation system is kept nearly equal to the planned total energy while the ACE（Area Control Error） is satisfied, as well as the actual 24-hour active power load curve to the planned one. The generated energy is corrected by velocity weighting factor to conduct dynamic regulation while the response speed is reached. Simulation is carried out with the practical operation data of Jiangsu power grid. Results show that the proposed strategy achieves the ACE regulation objective and realizes daily electric energy balance.
