The abstract is following

: The computation of power systems is highly complex due to its large-scaled, nonlinear, and nonconvex nature. In this talk, an artificial intelligence is introduced for capture the complexity of electric power industry under deregulated electricity markets. Secondly, the grid integration of nonconventional renewable energy resources is discussed in terms of reducing the large-scale of grids without sacrificing the structure of transmission networks. Lastly, the operation tool of the electric power industry, optimal power flow (OPF), is formulated and the complex nature is discussed. Due to the large scale and the large impact of electric power industry on the modern society, it would be ideal to seek for the global solution. However, the high complexity of the problem makes it practically impossible to achieve the solution. In this talk, I will introduce the state-of-art research achievement to efficiently find the global solution, the not-yet addressed problems, and the approach to attack the problems.
