Summary form only given as follows. This paper describes a capacitor commutated converter (CCC) model suitable for power flow and transient stability studies. The CCC control structure and important operational details are described. The practical advantages of the CCC as compared to the conventional HVDC converter are discussed. Results are presented for power flow, power system stability, small signal analysis and control design studies. These results clearly demonstrate the superior performance of a CCC link, when connected to a very weak AC system.

Due to the introduction of competitive electricity markets power trading becomes a central task within the operational activities of electric generating companies. Therefore the demand for planning tools that are able to support an integrated planning of power generation and trading becomes obvious. In this paper an optimization method for this planning task in companies with hydro-thermal generation park is presented. Computation results performed on a close to reality system show that the approach is able to find optimal decisions considering the risk attitude of the generating company.

Multi-megawatt energy storage facilities can offer a number of benefits to a utility. Some of these are improved power reliability, transmission stability, frequency regulation, energy arbitrage, and deferral of transmission upgrades. TVA is constructing a Regenesys energy storage facility at Columbus, Mississippi, which will provide several benefits to TVA and will provide a base of experience for future use of energy storage. This presentation gives an overview of TVA's Columbus Regenesys project and its expected benefits.

CIM XML model exchange presents new challenges for RTOs and ISOs due to the quality and sheer volume of model data being transferred. A significant percentage of modeling problems are extremely difficult to detect without tedious investigation. There is a large class of modeling errors that will pass undetected through traditional validation routines but are instantly made 'visible' by a one-line created directly from a CIM XML import. This presentation is an overview and demonstration of a one-line generation tool which was developed to quickly verify substation topology and power-flow results following CIM XML document exchange.

In this paper, a fuzzy-adaptive model for prediction of failure rates of overhead power distribution lines based on physical and weather related features is presented. The input data used and the results obtained are discussed. Also, results on sensitivity of failure rates to input features are provided. The overall aim of this presentation is to outline a methodology for feature-based prediction of failure rates of distribution system components. Since this method heavily depends of the input data and their accuracy, need for such databases is stressed.

Rotating machine interfaced power generation equipment today constitute the majority of interconnected distributed resources (DR). Even though new electronically interfaced DR devices, such as fuel cells, photovoltaics and microturbines are rapidly emerging, rotating machines are expected to continue to represent a major sector of interconnected DR capacity for the foreseeable future. To simulate and predict the impacts of these machines on power system control, protection and power quality conditions, it is crucial for the industry to have reasonable model representations of these devices. Machine models must characterize the prime mover response and generator electrical response behavior including its exciter. Critical types of analysis will include short circuit calculations (fault contributions), harmonic contributions, dynamic response of the generator to load steps and during islanding, voltage regulation, and stability. This paper is a starting point for discussing the modeling needs for rotating machine interfaced DR and potential sources of data for these models.

This paper describes the results of an assessment of various methods of identifying events whose impact on the reliability of electric service to customers is so severe as to dominate reliability statistics and mask the true design quality of the power delivery system or the true operational performance of the electric utility. Alternatives are compared based on realistic applicability within a utility and statistical results when applied to historical data from two major metropolitan areas in the USA.. A method based on the lognormal probability distribution applied to daily SAIDI is recommended. This work was part of an effort of the IEEE Power Engineering Society's Task Force on Reliability Indices.

An algorithm is given for the identification of a bifurcation subsystem, which experiences, produces, and causes bifurcation in the full system model. The algorithm applies the bifurcation subsystem and geometric decoupling condition tests to a sequence of partitioned models where the internal systems are of increasing order and are associated with the largest right eigenvector elements. The simplicity of this algorithm makes its application to large systems possible. The bifurcation subsystem condition and geometric decoupling condition that are sufficient conditions for existence of a bifurcation subsystem are also theoretically extended in this paper. It is thus shown that bifurcation subsystem method is more rigorously established since specific norms are introduced to represent the different system properties that allow a bifurcation subsystem to exist. The theoretical results provide more insight into the bifurcation subsystem method and why and when a bifurcation subsystem exists. This analysis reveals that the existence of a bifurcation subsystem requires much weaker conditions than that required for slaving, model reduction, coherency reduction, and a-decomposition methods. The bifurcation subsystem identification algorithm is then applied to a relatively large two-area differential algebraic modeled system with multiple generators.
