Abstract

Enhanced economic dispatch control of the wide area Interconnected Power System (the IPS) with effective interchange power flow balancing is presented. The algebraic expressions valid for online computations of the best gain values for the automated generation control (AGC) have been specified to provide suboptimal control processing for the area, or regional electric power system (EPS). Relevant operational conditions for secondary frequency and power control system were determined to compensate electric power flow imbalances in certain control areas (regional EPS) of the considered IPS. To apply the best AGC gain tunings, relevant numerical values of current power imbalances should be used for computations and proposed algebraic expressions are to be embedded seamlessly into the AGC algorithms of the SCADA-based multifunctional digital automated control system, which is already operated now to provide consistent controllable support for the normal processing inside the IPS. The AGC controllers of the SCADA-based system should be tuned periodically according to the proposed approach and the gain values updated properly.

互联能源系统中交换潮流的强化控制

提出了一种基于有效交换潮流均衡的广域互联电力系统经济调度控制方法。为提供区域或区域电力系统(EPS)的次优控制处理，给出了在线计算自动发电控制(AGC)最佳增益值的有效代数表达式。确定了二次频率和功率控制系统的相关运行条件，以补偿所考虑的IPS的某些控制区域(区域EPS)的潮流不平衡。为了实现最佳的AGC增益调谐，应使用当前功率不平衡的相关数值进行计算，并将所提出的代数表达式无缝嵌入到基于scada的多功能数字自动化控制系统的AGC算法中，该系统现已运行，为IPS内部的正常处理提供一致的可控支持。基于scada系统的AGC控制器应根据所提出的方法进行周期性调谐，并适当更新增益值。
