Abstract
The aim of load frequency control (LFC) is to save the frequency at the allowable limits ‎in different zones of power system operation. The advanced control system has a lot of advantages ‎over conventional integral controllers in practical applications. In this paper, LFC for a single area ‎system using a Linear Quadratic Gaussian Method (LQG) and a coefficient diagram method ‎‎(CDM) has been developed. Furthermore, an improved technique based on Multi-Verse ‎Optimizer (MVO) is applied for optimal adjustment for the LQG controller. In order to control ‎the turbine load output, the governors’ parameters must be adjusted to reduce the error rate and ‎increase confidence in the proposed system. The CDM system has been studied in theory for its ‎own transactions and data, in order to take advantage of the governor and turbine model for its ‎response and high efficiency. The division of the frequency value and all system transactions are ‎identified using the Kalman filter where they are controllers in the LQG module, this provides an ‎ideal income signal for the system. The strength and effectiveness of the model give an initial ‎impression of the extent of taking advantage of a practical system, so digital simulation must be ‎used for access to the target. The behavior of non-confidence in the performance of the system ‎has been addressed, and this has enhanced the results of simulation for a comprehensive and ‎integrated performance with (CDM + LQG). The control process was evaluated by a comparison ‎between the proposed scheme and only CDM.
