Generation capacity adequacy studies use two-area or multi-area models and available transfer capability to consider transmission limitations in getting emergency capacity assistance from neighboring systems. This paper discusses the role a composite system reliability model could have in an integrated analysis of generation and transmission adequacy.

Direct communication, broadcast to a variety of customer-premise load reduction technologies, is an effective way to pre-empt price spikes due to congestion or supply shortfall. With a multi-tier group addressing structure and an open-access nationwide communication network, direct control can be called by any of the power delivery participants for system security, based on electrical location, geographic location, load type, or program name. Direct control is extremely fast-acting, and well distributed; most programs do not require notification or customer intervention, and in a "pool/proxy" environment, could be used by all grid participants.

This is a summary in support of a presentation by the authors on various issues surrounding the deployment of distributed generation (DG) on US electric power systems. This is a survey of the numerous issues both driving and inhibiting the acceptance of DG. While DG may not be the panacea many envision, it certainly has a place. In this presentation, the authors sort through the real and perceived issues of DG from an 'in the trenches' perspective to increase understanding of the economic and technical issues.

Following the electricity market opening, new producers are plugging into the network. Therefore it is very important for any system operator to control, at all times, a producer's performances and characteristics. Estimation of parameters from power system measurement is a relatively new and unexplored field. It is complicated by the nonlinear nature of system dynamics and the size of the models. This paper shows a Gauss Newton approach involving trajectory sensitivities to estimate dynamic and controller performances. A theoretical approach of trajectory sensitivity, i.e., the sensitivity of the model response to small variations in parameters or initial conditions, is provided. An example, consisting of a 4-machine test power system, is used to illustrate the estimation algorithm.

This paper proposes a new approach to compute the maximal power system steady-state security regions using optimization approach. The maximal steady-state security region-hyperbox-is directly computed through a linear programming (LP) model, in which the upper and lower limits of each component forming a hyperbox are taken as unknown variables, and the objective is to maximize the sum of the generators' power adjustment ranges. For the first time, both fuzzy branch power flow constraints and the N-1 security constraints are introduced into the study of the steady-state security regions. A new idea of "N-1 constrained zone" is also adopted to calculate the all N-1 security constraints so as to reduce the computation burden. The steady-state security regions with fuzzy power constraints are successfully calculated on the IEEE 6-bus system.

The emergence of new technologies and more powerful computers as well as an increased demand for even more reliable power has created an opportunity for power engineers to improve the analysis done on power systems. System analysis for both generation and transmission has been studied in depth for many years. Recent activities related to de-regulation have changed the analysis paradigm requiring some new analysis techniques in these areas. However, the area of distribution systems provides an enormous opportunity for new system analysis. In some cases transmission analysis can be modified and applied to distribution systems. However, in most cases, the configuration and characteristics of the distribution system require both the models used and the algorithmic techniques to be redone to incorporate the system’s constraints.

This paper presents a multi-converter (modular) active power filter for high power nonlinear loads harmonic mitigation. The proposed system comprises of a Current Regulated Pulse Width Modulation inverter (CRPWM) modules that are utilizing a novel space vector modulation (SVM) based hysteresis current controller (HCC). The proposed methodology exploits the combined advantages of both HCC and SVM techniques. A set of space vectors including the zero vector, to reduce the number of switching, is determined from two sets of hysteresis comparators. One comparator set has larger hysteresis band than the other set. As a result, the proposed system significantly reduces the number of switching and, therefore, increases the efficiency of the power electronics modules.

This paper proposes a methodology for the design of automatic load shedding against voltage instability. In a first step, the authors describe a method allowing to find the minimal shedding required in a given unstable scenario. In a second step, they describe the structure of various controllers and identify the parameters to be optimized. Next, they present an optimization approach to find the controller parameters which optimize an overall performance objective. Results are presented on the Hydro-Quebec system, in which load shedding is presently planned.
