In a first step, a set of training scenarios is set up, corresponding to various operating conditions and disturbances. Each scenario is analyzed to determine the minimal load shedding which stabilizes the system, with due consideration for the shedding location and delay. In a second step, the parameters of a closed-loop undervoltage load shedding scheme are determined so as to: (i) approach as closely as possible the optimal sheddings computed in the first step, over the whole set of scenarios; (ii) stabilize the system in all the unstable scenarios; and (iii) shed no load in the stable ones. The corresponding optimization problem is solved using a (micro-)genetic algorithm. A detailed example is given on the Hydro-Quebec system in which load shedding is presently planned.","PeriodicalId":286352,"journal":{"name":"2000 IEEE Power Engineering Society Winter Meeting.

The Newton Raphson and fast decoupled load flow solution technique and a host of their derivatives have efficiently solved the well behaved power systems for a long time. However, the distribution networks, because of the some of the following special features, fail in the category of ill-conditioned power systems for generic Newton Raphson and fast decoupled load flow methods: radial or near radial structure (weakly meshed); high R/X ratios; multi-phase, unbalanced operation; unbalanced distributed load; and dispersed generation. Hence the need for special techniques for solving distribution networks which exploit their radial nature have long been identified.","PeriodicalId":286352,"journal":{"name":"2000 IEEE Power Engineering Society Winter Meeting.

Extended interconnected systems experience stability problems and inter-area oscillations, which can lead to system interruptions. Furthermore, long distance AC transmission requires reactive power compensation, introducing stability constraints that limit transmitted power. These conditions can be improved by the use of FACTS controllers. These improvements can be predicted by the proper simulation of FACTS controllers, which include all controls and a detailed representation of the system. Hence, this paper discusses FACTS controller models used through various analysis and design steps on FACTS projects. Examples of application studies of these controllers are also presented.","PeriodicalId":286352,"journal":{"name":"2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat.

A versatile distribution system simulation known as VIPCROP, which integrates load flow, fault current calculation and modeling of overcurrent relays and breaker operation, is proposed and developed. It is aimed to provide a visually integrated tool for operational planning, assessment of overcurrent relay settings, evaluating network proposals and for real-time fault diagnosis and supply restoration. The simulator implements the SCADA type of full graphic display of the single-line diagram superimposed with the calculated line current flow during normal condition, and the calculated fault current distribution and breaker tripping time during fault conditions. In contrast with the conventional load flow and fault current calculation programs, the proposed simulator-type of approach enables the user to operate a circuit breaker, activate a fault at a particular location, start a large motor at a particular bus, or change a transformer's tap-ratio. The immediate effects of the user's operation are modeled and the results are visually displayed on the single-line diagram similar to the real time display of operating a network in a control center. In addition, while operating the system, the user can visually modify the network such as adding a new bus, a new line or changing the settings of a particular relay. Thus, it serves as a very useful tool for both network operation and network planning.","PeriodicalId":286352,"journal":{"name":"2000 IEEE Power Engineering Society Winter Meeting.
