High penetration of renewable generation will increase the requirement for both operating reserve (OR) and frequency response (FR), due to its variability, uncertainty, and limited inertia capability. Although the importance of optimal scheduling of OR has been widely studied, the scheduling of FR has not yet been fully investigated. In this context, this paper proposes a computationally efficient...
Turbine blade tip clearance of aero-engine is of great significance for its efficiency, fuel consumption, running state and detection of faults. Previous researches on operation state monitoring and faults diagnosis of aero-engine turbine vane based on the measurement of blade tip clearance only focused on one-dimensional blade tip radial clearance. But the turbine blade tip clearance manifested as...
Estimation of Distribution Algorithms (EDAs) can be viewed as the outcome of the cooperation between evolutionary computation and probabilistic graphical models. In this paper, we review some continuous EDAs based on Gaussian network model and discuss their some known problems briefly. To prevent premature convergence and repair singular covariance matrix, we propose the PCA-EDA algorithm which integrates...
