一、引言随着国民经济的发展和国家劳动制度的改革，人们的消费结构和用电需求也发生了相应的调整，体现在电力系统中则比较明显的是电力负荷的变化。这同时也给电网带来了一些问题，尤其是国民经济的发展直接造成峰谷差的增大和各种不确定负荷的增多，给电网的调峰、调频造成 I.

It is obvious that changes in the power load are reflected in the power system. At the same time, it also brings some problems to the power grid. In particular, the development of the national economy directly leads to an increase in the peak-to-valley difference and an increase in various uncertain loads, causing peaking and frequency modulation in the power grid.
