计及故障持续时间的电力系统暂态稳定分布式控制
Transient stable distributed control of power system grid considering fault duration
摘要
Abstract
A strategy for restoring power system transient stability in a fixed time is proposed to address the issue that the duration of power system fault affects transient stability control.This strategy creates a"neighbor generator"for each generator by the power system communication topological modeling method,and uses the local information of the generator and that of its neighbor generator to design a distributed controller that acts on the disturbed system through controlling the energy storage device to restore its stable operation in a fixed time.Secondly,this control strategy tackles various practical challenges,such as the input delay of the controller,external interference,and the capacity constraint of the energy storage device.By constructing a Lyapunov function and using graph theory,a stability analysis of the strategy is developed,and then the time-bound of the stable system is derived.Finally,the controller is compared to other controllers using the New England 39-bus test system.The simulation results demonstrate the performance advantages of the controller under the restriction of low capacity energy storage device and the property of anti-interference.关键词
