Compensation techniques

Definition

Compensation techniques refer to various methods used in power systems to improve stability and performance by balancing load and generation while minimizing disturbances. These techniques are essential in maintaining system reliability, especially during fluctuations or faults, ensuring that the system can quickly return to a stable operating condition. They include approaches such as automatic voltage regulation, phase shifting transformers, and reactive power support.
