Artificial neural network was considered in previous studies for prediction of engine performance and emissions. ICA methodology was inspired in order to optimize the weights of multilayer perceptron (MLP) of artificial neural network so that closer estimation of output results can be achieved. Current paper aimed at prediction of engine power, soot, NOx, CO2, O2, and temperature with the ai...

Suppress of oscillations in power system is an important research issue. This paper deals with a robust controller design using the Imperialist Competitive Algorithm (ICA) optimization technique for Thyristor Controlled Series Compensation (TCSC) to improve the damping of oscillations in power systems. The design problem of TCSC based stabilizer is formulated as an optimization problem where th...

The connection points between MV and LV distribution networks are MV substations. Optimal sitting, sizing and timing of MV substation placement is the major planning problem in MV-LV distribution system planning projects. In this paper the optimal MV substation placement problem is solved using Imperialist Competitive Algorithm (ICA) as a new developed heuristic optimization algorithm. This pro...

Using meta-heuristic approaches to solve reliability and redundancy allocation problems (RRAP) has become attractive for researchers in recent years. In this paper, an optimization model is presented to maximize system reliability and minimize system cost simultaneously for multi-state weighted k-out-of-n systems. The model tends to optimize system design and maintenance activities over functio...

Combined heat and power (CHP) systems are employed to supply electrical thermal loads of distribution networks (DNs). However, the loss can significantly hinder transfer through pipelines from CHP consumers Therefore, optimal placement sizing reduce losses, including very crucial. To minimize loss, many methods have been proposed for resource allocation. In this paper, a new approach allocation...

In this research work, first, based on the three-dimensional elasticity theory and by means of the Generalized Differential Quadrature Method (GDQM), free vibration characteristics of functionally graded (FG) rectangular plates resting on Pasternak foundation are focused. The two-constituent functionally graded plate consists of ceramic and metal grading through the thickness. A three-parameter...

This paper presents a Imperialist Competitive Algorithm (ICA) to seek the optimal number and location of FACTS devices in a power system. Unified Power Flow Controller (UPFC) has great flexibility that can control the active and reactive power flow and bus voltages, simultaneously. Decoupled model of the UPFC is applied to maximize the system loadability subject to the transmission line capacit...
