ABSTRACT: Power system stability
control is a challenging task in power generation, transmission and
distributions based applications and in many fields. Multi-machine power
compensation control can achieve system stabilization within a prescribed time
in conventional controller. However, limited time control cannot guarantee the
system convergence within particular time independent on the initial condition,
which makes illegal application into the practical system if the initial
condition is unknown in advance. The proposed Multi-Machine Power System
Compensation (MMPSC) control overcomes the issues in existing systems and
limited time stability controller. Due to this attractive solution,
multi-machine power compensation control stability has found applications in
uniform exact differentiator design for the multi-agent system. The proposed
multi-machine power compensation control reduces damping oscillation and
improves the power system stability control. The main objective of proposed
controller is to improve the stability of MMPSC limited time system
stabilization independent of the initial state and ensure fast convergence both
far away from and at a close range of the power monitoring system. This feature
can reduce the loss caused by unwanted oscillation and avoid voltage collapse.
To overcome the linearity problem of terminal mode control, saturation function
is introduced to limit the amplitude of power input. In comparison with the
existing results on stability control, the proposed MMPSC applies a simpler
method to overcome stability problem and achieves higher
efficiency.
