A novel apparatus is introduced in this paper used to measure high voltage electric energy based on three-phase four-wire virtual-ground theory.The virtual-ground design,Faraday shielding technique and Warner DC (Direct Current) self-supply method are integrated in this apparatus based on new I/V.V/V techniques to realize high accuracy,reliability and wide-linear range measuring.The effectiveness of the apparatus has been proved by in-house calibration and on-site test.The test result shows that it can be used in high voltage grid on-site calibration.Its measurement uncertainty can be limited to 0.1％ under the condition of PF=1.0～0.8,and can reach 0.15％ as PF=0.5.In summary,the apparatus discussed in this paper can be applied as high voltage electric energy measurement instrument to meet the requirement of online metrological verification and calibration.Furthermore,it is very useful for building the system of Advanced Metering Infrastructure (AMI) in smart grid.

A lot of photovoltaic generations will be installed in power system in future. This will largely affect the power flow in the system, and consequently voltage characteristics. From these reasons, it is expected that the voltage stability will be also affected. In the previous study, the voltage stability in the simple power system consisting of one infinite bus, one load, and one photovoltaic generation is discussed. In this paper, the voltage stability considering the shutdown and recovery of the photovoltaic generation is studied.

Clean coal refers to the process of reducing carbon emissions and other harmful pollutants that arise from the burning of coal for power generation to the minimum possible level. SC, USC, and IGCC technologies are clean coal technologies that are widely used for setting up new-build coal-fired power plants. The more sophisticated the technology, the higher the steam pressure and temperature requirement is for operating the plant. As a result, the thermal efficiencies improve with the usage of more sophisticated technology. As well as these three technologies, CCS is also an upcoming technology, which is capable of reducing carbon emissions drastically by 80-90 percent. This technology is used in conjunction with SC, USC or IGCC plants.

Power system computation software tools are traditionally designed as serial codes and optimized for single-processor computers. They are becoming inadequate in terms of computational efficiency for the ever increasing complexity of the power grid. The power grid has served us remarkably well but is likely to see more changes over the next decade than it has seen over the past century. In particular, the widespread deployment of renewable generation, smart-grid controls, energy storage, plug-in hybrids, and other emerging technologies will require fundamental changes in the operational concepts and principal components of the grid. The grid is in an unprecedented transition that poses significant challenges in power grid operation. Central to this transition, power system computation needs to evolve accordingly to provide fast results for power grid management. On the other hand, power system computation should and has to take advantage of ubiquitous parallel computers. To bring HPC to power grid applications is not simply putting more computing units against the problem. It requires careful design and coding to match an application with computing hardware. Sometimes, alternative or new algorithms need to be used to maximize the benefit of HPC. This chapter demonstrates the benefits of HPC for power grid applications with several examples such as state estimation, contingency analysis, and dynamic simulation. These examples represent the major categories of power grid applications. Each of the applications has its own problem structure and data dependency requirements. The approach to apply HPC to these problems has different challenges. The HPC-enhanced state estimation, contingency analysis, and dynamic simulation presented in this chapter are suitable for today's power grid operation.

This report describes a component-based cost model developed for molten-salt power tower solar power plants. The cost model was developed by the National Renewable Energy Laboratory (NREL), using data from several prior studies, including a contracted analysis from WorleyParsons Group, which is included herein as an Appendix. The WorleyParsons analysis also estimated material composition and mass for the plant to facilitate a life cycle analysis of the molten salt power tower technology. Details of the life cycle assessment have been published elsewhere. The cost model provides a reference plant that interfaces with NREL's System Advisor Model or SAM. The reference plant assumes a nominal 100-MWe (net) power tower running with a nitrate salt heat transfer fluid (HTF). Thermal energy storage is provided by direct storage of the HTF in a 2-tank system. The design assumes dry-cooling. The model includes a spreadsheet that interfaces with SAM via the Excel Exchange option in SAM. The spreadsheet allows users to estimate the costs of different-size plants and to take into account changes in commodity prices.

Power system simulations involving solution of thousands of stiff differential and algebraic equations (DAE) are extremely computationally intensive and yet crucial for grid security and reliability. Online simulation of minutes to hours for a large number of contingencies requires computational efficiency several orders of magnitude greater than what is todays state-of-the-art. We have developed an optimized simulator for single contingency analysis using efficient numerical algorithms implementation for solving DAE, and scaled it up for large-scale con-tingency analysis using MPI. A prototype parallel high speed extended term simu-lator (HSET) on in-house high performance computing (HPC) resources at Iowa State University (ISU) (namely Cystorm Supercomputer) is being developed. Since the simulation times across contingencies vary considerably, we have focused our efforts towards development of efficient scheduling algorithms through work stealing for maximal resource utilization and minimum overhead to perform faster than real time analysis. This chapter introduces a novel implementation of dynamic load balancing algorithm for dynamic contingency analysis. Results indicate potential for significant improvements over the state-of-the-art methods especially master-slave based load balancing typically used in power system community. Simulations of thousands of contingencies on a large real system were conducted and computational savings and scalability results are reported.
