Over the past three decades the Town of Hull, MA has solidified its place in U.S. wind energy history through its leadership in community-based generation. This is illustrated by its commissioning of the first commercial-scale wind turbine on the Atlantic coastline, the first suburban-sited turbine in the continental United States, pursuit of community-based offshore wind, and its push toward creating an energy independent community.

The information technology (IT) world has changed fundamentally and drastically from running software applications on a single computer with a single CPU to now running software as services in distributed and parallel computing environment. Power system operation has been also shifted from being solely based on off-line planning study to more and more real-time market-driven. Facing these challenges, we will discuss in this chapter how to design power system analysis and simulation software to take advantage of the new IT technologies and to meet the real-time application requirements, using the InterPSS project as a concrete example.

The uncertainty and variability associated with photovoltaic (PV) generation make it very challenging to balance power system generation and load, especially for high penetration cases. Higher reserve requirements and more cycling of conventional generators are generally anticipated for large-scale PV integration. However, whether the existing generation fleet is flexible enough to handle the variations and how well the system can maintain its control performance are difficult to predict. The goal of this project is to develop a software program that can perform intra-hour dispatch and automatic generation control (AGC) simulation, by which the balancing operations of a system can be simulated to answer the questions posed above. The simulator, named Electric System Intra-Hour Operation Simulator (ESIOS), uses the NV Energy southern system as a study case, and models the systems generator configurations, AGC functions, and operator actions used to balance system generation and load. Actual dispatch of AGC generators and control performance under various PV penetration levels were assessed by running ESIOS. The results could provide system operators with more insights on what to expect with different amount of PV generation in the system. This report describes the design of the simulator and presents the study results.

This report analyzes the potential economic impacts in Colorado and Wyoming of a 225 MW natural gas fired electricity generation facility and a 900 MW wind farm constructed in Wyoming as well as a 180 mile, 345 kV transmission line that runs from Wyoming to Colorado. This report and analysis is not a forecast, but rather an estimate of economic activity associated with a hypothetical scenario.

This chapter has presented the background to power system dynamics, as appropriate for use in a modelling study of a power system. The complexities of the models depend on the type of transient and the system being investigated. Since we are mostly concerned about the frequency control of the power system, more effort has been placed on the active power flow in the system. Generally, the components of the power system that influence the electrical torque include the network state before and after the transient, the loads and their characteristics, the synchronous generator, the speed governor and other supplementary controls such as tie-line power flows.

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.
