This paper presents transient stability analysis and enhancement of Industrial Cogeneration Plant (ICP) using Artificial Neural Network (ANN) based adaptive load shedding. By selecting the total in-plant generation, spinning reserve, total plant load and rate of change of frequency as the input neurons of the ANN, the minimum amount of load shedding is determined to maintain in-plant load-gener...

The voltage instability in power system increases with power demand and over stressing of existing transmission lines nearly to their limits. A serious type of voltage instability is voltage collapse. In this paper comparative study of two techniques, namely Voltage Collapse Prediction Index (VCPI) and Sensitivity analysis to find voltage collapse vulnerability of bus in a power system is done....

The paper presents a Special Protection Scheme solution for the central Zagreb transmission system. The Central Zagreb transmission system is characterized by a highly meshed network with combined overhead and cable sections and a special operation of the 110 kV cable link between two power plants important for the city’s heat and electricity supply. The Special Protection Scheme is developed u...

In this paper, the effect of time dependence of control actions used to avoid voltage collapse, such as reactive power compensation and load shedding, is studied. A thorough justification of the phenomena under study is first presented with the help of a simple test system. The time dependence of the control actions is then studied in a real voltage collapse scenario of the Chilean Interconnec...

power system blackouts have become a serious problem for electric utilities especially in recent years. different forms of system instability have emerged in recent blackouts, such as voltage instability and frequency instability. to counteract each form of system instability, special algorithms have been designed in the protection system, e.g. under frequency load shedding (ufls) and under vol...

A temperature and rate-dependent crystal plasticity framework has been used to examine the temperature sensitivity of stress relaxation, creep and load shedding in model Ti-6Al polycrystal behaviour under dwell fatigue conditions. A temperature close to 120°C is found to lead to the strongest stress redistribution and load shedding, resulting from the coupling between crystallographic slip rate...

Research in the area of power system, incorporating optimal power flow and optimal load shedding, has been used in classical dispatch problems to determine control adjustments to remove line overloads. This paper reports a rule-based load shedding in a ship power system. To filter critical outages and congestion cases, a load shedding rule-based system is implemented. The algorithm searches for...

This paper addresses a multiagent-based distributed load shedding scheme to restore frequency for the microgrids during islanded operation. The objective of the proposed scheme is to realize a distributed load shedding considering its associated cost and the capacity of the flexible loads. There are two advantages of the proposed scheme: (1) it is a distributed scheme using average-consensus th...
