ELECTRIC POWER SYSTEM STABILIZATION CONTROL APPARATUS AND METHOD THEREOF

摘要

The present invention relates to a system and method for controlling fluctuations in a power distribution system. The system includes a system information input unit that takes in system information and a system state determining unit that determines states of the system. A component operation state determination unit is provided that determines operation states of system stabilizing components. A control plan deciding unit decides a control plan of the system in consideration of operation states of the system and the system stabilizing components. In deciding the control plan, a swing mode analysing unit firstly analyzes the swing mode at each location of the system on the basis of waveforms of time domain response simulations. A control allotment setting unit then determines control allotment for each of the system stabilizing components based on the mode analysis and a control parameter setting unit control sets the control parameters of each of the system stabilizing components. If plural control plans are obtained, the optimal one is selected based on eigenvalues of the dynamics of the system or by evaluating time domain system responses by simulation method. The decided control plan is output to the system stabilizing components by a control plan output unit.
