This paper provides a new framework for modeling uncertainty in the input data for power system risk calculations, and the error bars that this places on the results. Differently from previous work, systematic error in unit availability probabilities is considered as well as random error, and a closed-form expression is supplied for the error bars on the results.

Decision tree methods: applications for classification and prediction

Language: English Chinese. Decision tree methodology is a commonly used data mining method for establishing classification systems based on multiple covariates or for developing prediction algorithms for a target variable. This method classifies a population into branch-like segments that construct an inverted tree with a root node, internal nodes, and leaf nodes. The algorithm is non-parametric and can efficiently deal with large, complicated datasets without imposing a complicated parametric structure. When the sample size is large enough, study data can be divided into training and validation datasets. Using the training dataset to build a decision tree model and a validation dataset to decide on the appropriate tree size needed to achieve the optimal final model. Data mining is used to extract useful information from large datasets and to display it in easy-to-interpret visualizations.

Probabilistic vs Deterministic Power System Stability and Reliability Assessment

Documenting results and develop a Risk Management Action plan avoid, minimize, mitigate Your risk management plan should involve updates as compliance obligations and organizational changes take place. These risk assessment templates are used to identify the risks to business and most of the time provide solutions to reduce the impact of these hazards. General risk assessment form Risk assessments should be reviewed at least annually, or after accidents, near misses and when significant changes in personnel or work practices occur. Monitoring recommendations are made by risk ranking environmental changes, highlighting the current knowledge gaps and providing research priorities to address them. The Bank requires that all envi-ronmental and social risks and impacts of the 2.

The power industry has undergone the significant restructuring throughout the world since the s. In particular, its traditional, vertically monopolistic structure has been reformed into competitive markets in pursuit of increased efficiency in the electricity production and utilization. Along with the introduction of competitive and deregulated electricity markets, some power system problems have become difficult to analyse with traditional methods, especially when power system stability, reliability, and planning problems are involved. Traditionally, the power system analysis was based on deterministic frameworks; but they only consider the specific configurations, which ignore the stochastic or probabilistic nature of real power systems. Moreover, many exterior constraints as well as growing system uncertainties now need to be taken into consideration.
