摘要:

为提前采取措施防范电力系统安全稳定水平下降,需要明确新能源革命对中国电力系统安全稳定性演变的影响。根据中国电力系统发展过程中电网规模的大小及其增长情况,划分了中国电力系统安全稳定性的4个发展阶段,总结了不同阶段电力系统存在的典型稳定问题,分析了各个阶段影响电力系统安全稳定性的主导因素,厘清造成安全稳定性转换的机制和原因。研究表明:新能源革命下电力系统安全稳定性与电力系统规模呈现解耦的特点,建议通过构筑电网演化模型、建立稳定水平综合评估指标,以量化和预测未来电力系统安全稳定水平变化趋势。

Abstract:

In order to take measures in advance to prevent the decline of the safety and stability level of the power system, it is necessary to clarify the impact of the new energy revolution on the evolution of the security and stability of China's power system. According to the scale and growth of the power grid in the process of China's power system development, the security and stability of China's power system is divided into four stages of development. The typical instability problems of the power system at different stages are summarized. The dominant factors affecting the security and stability of the power system at each stage are analyzed, and the mechanisms and causes for the conversion of security and stability are clarified. It is pointed out that under the new energy revolution, the security and stability of the power system appears decoupling from the scale of the power system. Proposals are made to construct a power grid evolution model and establish a comprehensive assessment indexes of stability level to quantify and predict the trend of future changes in the security and stability level of the power system.
