电力系统对角加边模型的数据中心求解方法
An Algorithm for Solving the Block Bordered Diagonal Form of Electrical Power System in Data Center
摘要
Abstract
With the advent of large-scale regional interconnected power grids as well as the utilization of the phasor measurement unit (PMU) and intelligent electronic devices (IEDs) in electrical power systems becoming more common, the analysis of petabyte sized data has become a primary focus in research communities. Cloud computing, which is a form of data storage on the Internet, increases the possibility to implement a tool for analyzing large datasets in power systems and parallel computing in complex grids. This paper proposed a new optimized method for the mapping of block bordered diagonal form (BBDF) and decomposition-coordination algorithms for cloud computing data centers. Based on the computational complexity of coupling between tasks, the decomposition-coordination algorithm had been split to perform different tasks, and to judge the amount of calculation. A binding placement algorithm also was presented as a method to map the tasks into virtual machines (VM). A new energy-efficient Bin-Packing model was built for the final mapping step, which is the process of transferring the data from the VMs to the data centers. This will be performed while ensuring that the constraints of CPU and memory utilization rate are in check. IEEE 118 node grid model, as well as two large-scale power systems, which utilizes 538 and 1133 nodes systems, were calculated through the CloudSim platform. The results suggest that data centers using the virtual machine technology are more effective than the use of traditional parallel computing methods in terms of time and system energy consumption. In the IEEE 118 nodes system, the total <br> processing time has reduced to 43.2%, and with the system size increasing, the 1133 nodes system experienced a 75.8%decrease.关键词
