Contingency Constrained Power System Security Assessment using Cascade Neural Network

A unified approach to power system security assessment and contingency analysis suitable for on-line applications is proposed. The severity of the contingency is measured by two scalar Performance Indices (PIs): Voltage-reactive power performance index, PIVQ and line MVA performance index, PIMVA. In this paper, a two stage cascade neural network is developed: Stage I employs Multi-Layer Percept...

Power system security analysis under transmission line outage condition

The power system becomes more severe under contingency conditions. In general, the contingencies may be outage of transmission lines or generators. To identify the effect of outages on system security, the contingency analysis is one of the analytical tools. The congestion on a system must be manages using generation rescheduling and with the proper control of the compensation equipments. The t...

An integrated model for designing a distribution network of products under facility and transportation link disruptions

Due to occurrence of unexpected disruptions,a resilient supply chain design is important. In this paper, a bi-objective model is proposed for designing a resilient supply chain including suppliers, distribution centers (DCs), and retailers under disruption risks.The first objective function minimizes total costs. The second objective function maximizes satisfied demands. We use the augmented e-...

Optimizing location, routing and inventory decisions in an integrated supply chain network under uncertainty

This study extends a mathematical model that integrates the location, allocation, inventory replenishment and routing decisions simultaneously. To cope with inherent uncertainty of parameters, we implement a continuous-time Markov process and derive the performance measures of the system. Using the obtained results, the problem is formulated as a mixed integer nonlinear programing model (MINLP)...
