Drug addiction is one of the main problems of modern societies that is affected by many factors, especially external factors. Therefore, governments are looking for the solutions to minimize the damages from addiction. This paper seeks to answer the question of how to deal with the drug-abuse problems and comparing the effectiveness of the reactive approach against the proactive approach? First...
This paper presents a new approach for estimating and improving voltage stability margin from phase and magnitude profile of bus voltages using sensitivity analysis of Voltage Stability Assessment Neural Network (VSANN). Bus voltage profile contains useful information about system stability margin including the effect of load-generation, line outage and reactive power compensation so, it is ad...
According to the latest developments in smart grid infrastructures of recent modern networks, in this paper, end-consumers are presented as a means for participating in networks voltage distribution control. In this regard, for reactive power control of the smart grids, a distributed control approach is proposed as an efficient approach which improves computation burden of the problem, consider...
in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....
In this paper, the problem of sequencing machines in the final assembly line with regard to the supply of parts has been investigated. For this reason, a basic integer linear programming model has been developed and based on this, the problem-solving algorithm is developed in accordance with the reaction-based approach based on the renewal of the sequence of operations. Also, due to the Np-hard...
In this paper, a distributed method for reactive power management in a distribution system has been presented. The proposed method focuses on the voltage rise where the distribution systems are equipped with a considerable number of photovoltaic units. This paper proposes the alternating direction method of multipliers (ADMMs) approach for solving the optimal voltage control problem in a distri...
