Power grid is a very large scale and highly non-linear dynamical system, and its stable and reliable operation poses a great challenge to scientists and engineers. As a complex dynamic network has a tendency of catastrophic failure, sophisticated analysis and control are required. In an interview with NSR, Professor Yusheng Xue, member of the Chinese Academy of Engineering, Honorary President of China's State Grid Electric Power Research Institute, talked about the economic impact, technical challenges, and future development of power grid in China.
In this technical note, we propose a practicable quantized sampled velocity data coupling protocol for synchronization of a set of harmonic oscillators. The coupling protocol is designed in a quantized way via interconnecting the velocities encoded by a uniform quantizer with a zooming parameter in either a fixed or an adjustable form over a directed communication network. We establish sufficient conditions for the networked harmonic oscillators to converge to a bounded neighborhood of the synchronized orbits with a fixed zooming parameter. We ensure the oscillators to achieve synchronization by designing the quantized coupling protocol with an adjustable zooming parameter. Finally, we show two numerical examples to illustrate the effectiveness of the proposed coupling protocol.
