摘要

本文提出了一种采用超导磁能储能的两区互联水热系统的AGC改进方案。还考虑了发电速率约束。采用积分平方误差技术获得积分增益设置的最优值。分析表明,在存在中小企业单位的情况下,动态响应得到了相当大的改善。通过对无GRC和有GRC的机组动态性能的比较和分析,发现了有GRC的机组在抑制频率和区域间连接功率偏离标称值后的阶跃负荷扰动方面的优越性能。

AGC of a hydrothermal system with SMES unit
In this paper, the AGC improvement of a two area interconnected hydrothermal system along with a Superconducting Magnetic Energy Storage is proposed. Generation Rate Constraints are also considered. Integral Squared Error technique is used to obtain the optimum values of the integral gain settings. Analysis reveals that the dynamic responses are considerably improved in the presence of the SMES unit. A comparison and analysis of the dynamic performances without and with SMES unit in the presence of GRC brings out the superior performance of the SMES unit in suppressing the frequency and inter-area tie-power deviations from their nominal values followed by a step load perturbation.
