ABSTRACT The integration of large amount of wind generation will have significant impact on both long-term planning and real-time operation of power systems. The intermittent and energy-limited characteristics are important factors in wind generation integration modeling. In terms of probabilistic reliability, new wind generation interconnection cannot meet the adequacy requirement by itself as load increases. Addition of conventional capacity is needed to compensate the intermittency of wind generation. The same is also true in real time operation. Scheduling wind generation in real-time can result in the reduction of system security; hence the requirement of operating reserve may increase. Reliability assessment based on probabilistic method is used in this paper to evaluate the impacts of wind integration from different aspects of planning and operation of a power system. Different reliability models of wind generation are presented. The IEEE Reliability Test System (IEEE-RTS) system is used to demonstrate the developed wind modeling.

    ABSTRACT: Rather than the short-circuit current that would occur in a specific instance, International Electrotechnical Commission 60909 derives the maximum and minimum prospective short-circuit currents in a system for each specific location and time. This is reported using a series of parameters which relate to the rated short-circuit current of equipment and the tests required on equipment to prove that rating. The influence of arc voltage on short-circuit currents is then discussed.

    ABSTRACT: This paper describes a study conducted to address the question of how much power transfer capacity should be provided on a meshed transmission system to maintain reliability of supply to consumers in the presence of wind generation. A simulation methodology is presented that includes modeling of the available wind generation in the longer term across a quite large area taking into account correlations in available power between different locations in that area. A description is given of the results obtained in characterization of the relationship between the peak load in an area, the total generation capacity in that area, the proportion of it that is wind generation, and how much transmission import capability- “interconnection reserve” -is required for a given reliability of supply. Finally, a number of issues faced by power system investment planners are discussed and pointers given to further work to enable transmission utilities to meet the challenges presented by policy makers in respect of development of wind power to meet renewable energy targets.
