Minimising Voltage Deviation In Distribution Feeders By Otpimising Size And Location Of Distributed Generation, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Minimising Voltage Deviation In Distribution Feeders By Otpimising Size And Location Of Distributed Generation, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Faculty of Engineering and Information Sciences - Papers: Part A
A new emerging trend of distribution networks is to use small generating units, known as distributed generation (DG), operating in parallel with the main grid. This kind of distribution networks has enabled DG to support power systems in fulfi lling their requirements to increase power output as well as quality of power supply. In order to maximise benefi ts from the DG system, proper DG planning is necessary. The main purpose of this research is to maximise voltage support through optimal sizing and location of DG. A new methodology is developed to determine an optimal DG size and DG location …
Discovering Prediction Model For Environmental Distribution Maps, Ke Zhang, Huidong Jin, Nianjun Liu, Rob Lesslie, Lei Wang, Zhouyu Fu, Terry Caelli
Discovering Prediction Model For Environmental Distribution Maps, Ke Zhang, Huidong Jin, Nianjun Liu, Rob Lesslie, Lei Wang, Zhouyu Fu, Terry Caelli
Faculty of Engineering and Information Sciences - Papers: Part A
Currently environmental distribution maps, such as for soil fertility, rainfall and foliage, are widely used in the natural resource management and policy making. One typical example is to predict the grazing capacity in particular geographical regions. This paper uses a discovering approach to choose a prediction model for real-world environmental data. The approach consists of two steps: (1) model selection which determines the type of prediction model, such as linear or non-linear; (2) model optimisation which aims at using less environmental data for prediction but without any loss on accuracy. The latter step is achieved by automatically selecting non-redundant features …
A Novel Method For Load Flow Analysis Of Unbalanced Three-Phase Radial Distribution Networks, Masoud Aliakbar Golkar
A Novel Method For Load Flow Analysis Of Unbalanced Three-Phase Radial Distribution Networks, Masoud Aliakbar Golkar
Turkish Journal of Electrical Engineering and Computer Sciences
This paper presents a novel method for load flow analysis in radially operated 3-phase distribution networks without solving the well-known conventional load flow equations. The method can be applied for distribution systems in which the loads are unbalanced. As the size of matrix used is very small compared to those in conventional methods, the amount of memory used is very small, the speed is very high, and the relative speed of calculation increases with the size of the system. The method was applied to some practical networks and the results show the superiority of this method over the conventional ones. …
Corporate Blogs Of 40 Fortune 500 Companies: Distribution, Categorization And Characteristics, Shaoyi He, Jake Zhu
Corporate Blogs Of 40 Fortune 500 Companies: Distribution, Categorization And Characteristics, Shaoyi He, Jake Zhu
Journal of International Technology and Information Management
This paper studies corporate blogs as virtual communities, focusing on the distribution, categorization and characteristics of 40 Fortune 500 Companies’ blogs. Firstly, the 40 corporate blogs were classified by industries to see which industries are active advocates of corporate blogs. Secondly, the 40 corporate blogs were first grouped in direct competitor clusters and then categorized into four types of virtual communities: 1) Community of interest, 2) Goal-oriented community of interest, 3) Learner’s community, and 4) Community of practice. Thirdly, eight common elements were identified and compared for each of the 40 corporate blogs to find out their major characteristics. Finally, …
