The intermittent nature of wind poses significant problems to generation companies that wish to keep a close watch on the performance of their wind mills. A regular data mining process on historical measures becomes mandatory to analyze the behavior of each turbine, especially during periods of normal operation – that is when working regularly but with a possible loss of generation...
A data-mining-based prediction model is built to monitor the performance of a blade pitch. Two blade pitch faults, blade angle asymmetry, and blade angle implausibility were analyzed to determine the associations between them and the components/subassemblies of the wind turbine. Five data-mining algorithms have been studied to evaluate the quality of the models for prediction of blade faults. The...
Micro-siting of wind turbines is a key technology for wind farm configuration. In this paper, Weibull function is used to describe the probability of wind speed distribution and turbine speed-power curve is employed to estimate turbine power generation. The improved wind and turbine models are formulated into an optimal control framework in terms of minimizing the cost per unit energy of the wind...
This paper presents an optimization approach, harmony search algorithm (HS), to solve the economic dispatch (ED) problem in the power system integrating wind energy conversion system (WECS). Three optimization techniques, genetic algorithm (GA), interior point methods (ITP) and HS are applied to solve ED when system connecting and disconnecting to WECS. The results show that HS can give the better...
An efficient hybrid distributed genetic algorithm is proposed to determine the proper number and locations of wind turbines in large wind farms. The objective of this optimal process is to find a solution that maximizes the annual profit obtained from a wind farm. It is well-known that genetic algorithms are good for global searches, but are weak for local searches. To improve the performance of finding...
The operation of a radial distribution network in an islanded mode has become significant due to an increase in the integration of renewable sources to the utility network. In this project, a computational tool is presented to design the sizes of the distributed resources for an autonomous micro-grid operation of a radial distributor. The technique employs GA optimization, considers the variation...
