摘要

风电输出功率具有强随机性和波动性的特点，因此风电高占比带来的输入电能波动给多区负荷频率控制带来更大挑战。计及风功率预测误差对负荷频率控制的影响，且考虑到未来开放式通信环境对区域控制误差信号传输的影响，文中提出了一种基于事件驱动通信下的鲁棒负荷频率控制策略，以保证含风电电力系统频率稳定性的同时尽可能地减少网络通信传输量。以典型含风电的两区域负荷频率控制为例进行了仿真研究，仿真结果表明，文中所提出的基于事件驱动通信的鲁棒控制器相对于常规比例-积分控制器而言，不仅能够有效保证风功率波动下的频率输出的l2增益性能，还能减少系统平稳态的通信次数，具有良好的频率控制性能。

Abstract

Wind power output has the characteristics of uncertainty and fluctuation

so the input power fluctuation caused by the wind power with high proportion brings bigger challenges to multi-area load frequency control. Considering the impact of prediction error of wind power on the load frequency control and the impact of open communication environment in the future on area control error transmission

a robust control strategy of load frequency based on event triggering communication is proposed to maintain the frequency stability of power system with wind power and reduce the network communication as much as possible. The load frequency control of a typical two-area system with wind power is taken as the simulation case. The simulation results show that compared with traditional proportional-integral controller

the robust controller based on event triggering communication can not only effectively guarantee l2 gain performance of frequency output under the fluctuation of wind power

but also reduce the communication times in the steady state

which has good frequency control performance.
