摘　　要：在南方区域电力系统中采用控制性能标准(CPS)对区域内省级电力系统的自动发电控制(AGC)系统运行性能进行评价,并制定了相应的经济考核方法。以该方法为基础,在CPS计算公式中加入容量系数,把CPS考核方法推广到发电机组,并将省级的考核电量分解到相关电厂,以促进其改善运行性能。这种方法与现有CPS考核方法的思路一致,且侧重于机组较长时间段的调节性能,避免直接对机组动态性能指标如调节速率和调节精度的测定,方法简单,容易实现。In China Southern Power Grid, the well-developed control performance standard （CPS） is employed to assess the automatic generation control （AGC） operation performance of the dispatching centers at the provincial level, and on this basis an economic penalty mechanism is established. Given this background, by adding a capacity coefficient to the GPS formulas, the CPS assessment method is extended to accommodate generation units, and a new approach for assessing the AGC operation performance of generation units is developed. The penalty for each provincial dispatching center, in the form of electricity amount, is then allocated to the generation units based on the assessment outcomes, and as a result, this could provide an efficient incentive for those units to improve their operation performance. The proposed approach is consistent with the existing CPS assessment framework, and its emphasis is placed on the long-term regulation operation performance of the generation units. In this way, the AGC dynamic operation indices, such as the regulation rates and regulation accuracy, are not required, and hence the method could be implemented easily in actual power systems.
