Abstract:
<em>A power distribution network is simply an inter-connection of 33/11 kV power transformers, network in-feeds, distribution station buses and the loads. The security of such a system is of great consideration in power utilities. Thus, contingency analysis is often used to determine the security of such system. Several methods used in analyzing power system security include linear programming (LP), least squares (LS), decision trees (DTs), artificial neural network (ANN) etc. These methods were observed from literature to take a long computational period. Therefore, this paper presents a cont

Abstract:
The increased complexity of the transmission grid can endanger the operational security of the grid. Operational risk assessment, a stochastic tool, helps to enhance security. Contingency analysis and its impact quantification are the main constituents of operational risk assessment. In this study, different graphical methods are proposed to visualize operational risk contingency-based detailed results: heat-map and risk-based contingency chart. Through the heat-map, the system operator can determine which contingencies contribute most to the operational risk and would therefore be the most th

Abstract:
This paper deals with the security aspects of power system by evaluating the severity of transmission line outage. MW security assessment is made by determining the power flow in the line using load flow for each contingency. The severity of contingency is measured using a scalar index called performance index (PI). DC load flow and Fast Decoupled load flow are used as approximate and exact load flow methods for MW security assessment respectively. Contingency analysis is carried out and ranked lists in the decreasing order of severity based on PI values are prepared for standard test systems.

ABSTRACT Under the U.S. Environmental Protection Agency's (EPA) Oil Spill Prevention, Control, and Countermeasures (SPCC) program, facilities must complete an oil spill prevention and control plan. If a facility is unable to complete a control plan, a contingency plan must be completed in accordance with the SPCC regulations. A recent EPA SPCC Program Task Force found these regulations to be inadequate in several areas, including mandatory facility-specific contingency planning.

Abstract:
ABSTRACT Area Contingency Plans (ACPs) are generally evaluated using basic checklists designed to ensure completeness rather than to evaluate content. This approach encourages an increase in plan size, not plan quality, since only a plan that omits something is likely to be rejected (Abordaif, 1997). If an AC? is in the required format and contains masses of miscellaneous information, the prevailing method of assessment deems the plan a success. However, based on a review of a number of ACPs, many plans do not prepare the response community to accomplish tasks that are critical to success duri

Winning a bid at a price that yields a profit, is one of the contractor&#39;s major goals from bidding. One of the significant components of markup is the risk allowance (contingencies). Therefore, contractors should be wise to consider the likelihood that a particular risk will occur, identify the potential financial impact, and determine the suitable contingency allowance if the risk was to be mitigated through contingencies. Based on previous research, usually, most of the contractors set a percentage of the cost as contingencies. This approach of setting the contingency percentage intuitiv

One of the main objectives of electric power utilities keeping up a continuous and adequate power supply to the customers at a sensible cost. This paper contributes to the solution of the reliability and quality assessment problems in power systems, using the (N-2) outage contingency scenario to evaluate power system’s reliability and quality levels. Therefore, the methodology presented in this paper is based on the integration of reliability measures, quality indices, and contingency analysis. While reliability formulas have traditionally been applied to small and illustrative power systems,

&lt;span lang="EN-IN"&gt;Unit commitment state’s the strategic choice to be prepared in order to define which of the accessible power plants should be taken into account to supply power. It permits utilities to reduce generation price of power. In this paper, the unit commitment problem is elucidated by taking N-1-1 contingency as a foremost constraint. The standard N-1-1 contingency takes the loss of sequential two components in the network having intervening interval for network modifications in the middle of two losses. The crucial objective to carry out contingency constrictions is to make

Abstract:
This paper presents a methodology for static security assessment of transmission network planning using machine learning (ML). The objective is to accelerate the probabilistic risk assessment of the Hydro-Quebec (HQ) TransÉnergie transmission grid. The model takes the expected power supply and the status of the elements in a N−k contingency scenario as inputs. The output is the reliability metric Expecting Load Shedding Cost (ELSC). To train and test the regression model, stochastic data are performed, resulting in a set of N−k and k=1,2,3 contingency scenarios used as inputs. Subsequently, th

Purpose Most organisations do not have established guidelines for the estimation and management of contingency funds. The purpose of this paper is to identify the risk factors at the construction phase causing project cost overruns, and a reliable method for the estimation of contingency sum is established. Design/methodology/approach Combined qualitative–quantitative exploratory methods were used. Qualitative interviews were conducted with five expert practitioners working in a Public Works Department in Zambia to determine how contingency sum is estimated and to explore what risk factors sho
