AI Technical Summary
Existing AGC frequency regulation schemes suffer from slow response, unbalanced frequency regulation power distribution, complex mode switching, and high computational load under conditions of high proportion of new energy grid connection, making it difficult to achieve dynamic adaptation and stable control.
The cascade AGC regulation and control method is adopted. By decomposing the area control error (ACE) into frequency deviation and tie line power deviation, and combining the unit ramp rate and adjustable capacity, the frequency regulation power is dynamically calculated and weighted and allocated. The control parameters are optimized through online adaptive adjustment to achieve continuous frequency regulation without mode switching.
It improves frequency stability and the flexibility of frequency modulation resource allocation, ensures the effective utilization of rapid resources, reduces system peak frequency difference, and is suitable for real-time control of multiple frequency modulation resources.
