3126: New Capability Applications Based On Synchrophasor Measurements

Phase 1 of this project, namely the Phasor Measurement Unit (PMU) applications state-of-the art assessment, was completed and reported in August 2012. In the present report, the completed activities of Phase 2 are explained.The idea pursued in this phase is the innovative application of PMUs for generation shedding (also known as generation rejection). In other words, appropriate voltage magnitudes and angles (to be obtained from properly located PMUs) will be processed to derive the right amoun

3128: Short Circuit Contribution of Renewable Generation

This project addresses utility concerns related to the fault contribution from renewable generators, most prominently wind and solar generators. Accurate information of these fault contributions is needed for selecting equipment ratings and ensuring that the protective device coordination in power systems functions properly. The fault contribution from renewable generators, in particular inverter-based renewable generators, is fundamentally different from the fault contribution from conventional

3143: Best Practices for Incorporating Probabilistic Planning into Transmission Planning

For reliable and economic operation of power systems, electric utilities maintain sufficient generation, transmission, and distribution capacities to ensure continuity of electric services to their customers under normal and certain abnormal conditions. Deterministic criteria and techniques have been developed and employed by the utility industry in power system planning and operation for many years and will continue to be benchmark criteria.Considerable work published over the last several deca

3105: Transmission System Planning and Operation under Uncertainties, Phase I

This project identifies available tools and techniques for transmission planning and operation that include the uncertainties of generation and load conditions. While transmission system operators address these issues in various ways around the world, there is no commonly accepted, comprehensive approach. The application of probabilistic tools for scenario analyses is a method for addressing the uncertainty of unavailability and load growth. For transmission planning, composite reliability asses

3106: Use of Lightning Arresters to Protect and Improve Outage Performance of Unshielded Lines

The application of surge arresters to protect and improve the lightning performance of unshieldedtransmission lines is analyzed by means of a statistical simulation tool developed in the MATLABenvironment, in conjunction with EMTP‐RV. The lightning performance of three unshielded lineswith different configurations and different voltage levels is evaluated. The use of line surge arrestersto improve the line performance was examined for gapped as well as gapless arresters. In everycase, the possib

3113: Utility Design Practices and Operating Experience with Shunt Capacitor Banks

Shunt capacitor banks are applied universally on power transmission and distribution networks for power factor correction to regulate voltage and reduce losses. Their ratings typically range from 10 MVAr to 400 MVAr when applied at substations, depending on the level of reactive power compensation required. Because individual capacitor units are manufactured in ratings limited to about 20 kV, 1000 kVAr, numerous units need to be interconnected in series-parallel arrangements to support the desir

3114: Wide-Area Voltage Control

In this project, the potential for reliability and efficiency enhancements in electric power systems is demonstrated by means of the NETSS AC Extended Optimal Power Flow (AC XOPF). A systematic optimization of both real and reactive power/voltage available resources, AC XOPF can be used as a powerful decision-making tool on what to build and/or control, as system conditions vary. This software can significantly enhance operations, both during normal and non-time critical contingency conditions,
