An approach to calculate the wind farm penetration capacity based on chance constrained programming combining with transient check was presented. A novel model for programming penetration of wind farm under indeterminacy operating mode was presented. Constraint condition consisted of conventional generator output limits, system spinning reserve, transmission lines capability, nodal voltage, sys...

An integrated approach to reservoir, irrigation, and cropping management which links four di€erent modelsÐa hydrologic model (PRMS), a crop growth simulation model (EPIC), an economic model based on linear programming, and a dynamic programming modelÐis developed and demonstrated. The demonstration is based on an irrigation district located in a subhumid climate with an irrigation reservoir lar...

The tourism in Miaoli has been in great development recently. The wonderful scenery and other potential conditions have sufficient incentives to attract tourists. Though there is such a huge tourist economic market, most tourist service providers are unfortunately not able to integrate the information technology and the tourist services effectively. Therefore, we guide the tourism industry “Cas...

Conservation programs administrated by the United States Department of Agriculture under the Farm Bill have tremendous potential to impact wildlife habitat and populations on private land. Recent comprehensive reviews demonstrate that private landowners who participate in these programs have established habitats that may contribute to sustaining some regional wildlife populations. However, I ar...

Planning of modifications of existing wind farms by adding or replacing turbines makes new demands on wind farm modelling. Emphasis shifts from the calculation of the mean efficiency of the farm to that of individual turbines. Additionally, modelling has to deal with different turbine types and hub heights combined in one farm. Full scale measurements at two wind farms in Northern Germany provi...

If farmers are risk averse, greater farm income variability should increase off-farm labor supply. This effect is confirmed for a sample of Kansas farmers. Off-farm employment of farmers and their spouses is also found to be significantly influenced by farm experience, off-farm work experience, farm size, leverage, efficiency, and farm-specific education. In addition, farm operators and spouses...
