Optimal automatic generation control in a multi-area power system through combined state and control gain

Abstract EN

For optimum load frequency regulation, a combined estimate of state and feed-back gain is proposed.

One of the key research areas of power system operation is automatic generation control (AGC) or load frequency control (LFC), This technology reacts to disturbances in order to maintain system frequency.

Feedback stabilization is a well-known solution to this problem.

A control loop with LQR architecture uses parameters that are known to the system to compute the feedback gain K, and then applies power, assuming all state variables are available.

This study proposes enhancing state variables with controller gains.

As a result of system resource requirements fluctuating and the varying system parameter, the controller gains needed to regulate the system are provided.
