计及处罚费率的AGC机组调配经济性研究

Research on AGC of units allotment considering penalty rates

随着电力运营体制改革的不断深入和电力市场的逐渐形成,维持电力系统的经济可靠运行显得越来越重要,研究的重点也逐步转向了对辅助服务的有效获取和定价。通过对AGC机组的调配问题的研究,介绍了一种考虑到联络线偏差的确定AGC容量需求的框架和在目前的电力市场机制下针对不同需要来处理调节分配的方法。最后引入算例,通过与常规方法的比较,验证了该模型的正确性和有效性。

With the power industry of China is going to establish a market-based operational mechanism, it is more important to maintain system security an reliability while economically efficient transactions are accommodated in the power system. Meanwhile, restructuring has sharpened the appetite of generation owners for more efficient operation achieved by submitting auxiliary services as well as energy component. From the research of the deployment of AGC unit, a framework to determine AGC capacity requirement and to deal with regulation dispatch under uncertain demand in a competitive electricity market is presented in this paper. Furthermore, the numerical example is employed to validate correctness and effectiveness of the proposed algorithm, and the result based on this algorithm is compared with that based on conventional algorithm.
