This paper deals with the application of the concept of POM to analysis of power system behavior and describes a practical method of PRA for KEPCO system. This paper presents not only marginal power flow evaluation of KEPCO system in view point of physical and operation mode by using Physical and Operational Margins (POM Ver.2.2), which is developed by V&R Energy System Research, but also by using Probabilistic Reliability Assessment (PRA Ver.3.1), which is developed by EPRI. The ability of the method to provide insights on root causes, weak points and regional causes and effects was shown. The approach offers fast and accurate determination of bottlenecks in the transmission network and optimal mitigation measures to alleviate the identified violations.

This paper describes a probabilistic annual congestion cost assessment of a grid at a composite power system derived from a model. This probabilistic congestion cost assessment simulation model includes capacity limitation and uncertainties of the generators and transmission lines. In this paper, the proposed probabilistic congestion cost assessment model is focused on an annualized simulation methodology for solving long-term grid expansion planning issues. It emphasizes the questions of "how should the uncertainties of system elements (generators, lines and transformers, etc.) be considered for annual congestion cost assessment from the macro economic view point?". This simulation methodology comes essentially from a probabilistic production cost simulation model of composite power systems. This type of model comes from a nodal equivalent load duration curve based on a new effective load model at load points. The characteristics and effectiveness of this new simulation model are illustrated by several case studies of a test system.

The reliability evaluation methods for the bulk power system habe been studied by several electric utilities. The evaluation methods based on the probability theory and the computer packages are being developed or already practicalized. But without correct probabilistic data, accurate result couldn't be expected. In this point, the construction of database is needed. Some of probabilistic data for evaluation of bulk power system are shown in this paper.

An automated system for the structural analysis of chassis module are developed. The system can evaluate the deformation, strength and stiffness of the chassis module, when a heavy loads is applied at the wheel center or tire patch of the module. Part library, project model, and load files in the system are realized in the form of xml and are stored in a database for reuse. The system is actively being used in the vehicle developing process.
