Abstract

This paper presents a reliable approach for optimal reactive power dispatch based on chaotic particle swarm optimization with attractive search space border points, where the particles are randomly attracted to the boundary points of the search space in each direction avoiding stagnation of the population. The introduction of chaotic dynamics improves the stability and rate of convergence. The algorithm is further improved by using Latin Hypercube Sampling (LHS) to create diversity in the population. The proposed algorithm is used for optimal reactive power dispatch with three objective functions, namely: minimization of real power loss, voltage stability index, and sum squared voltage deviations. The algorithm is tested on a standard 30-bus system of the Institute of Electrical and Electronics Engineers (IEEE) and on a practical 75-bus Indian Power System. The results obtained with the proposed algorithm are compared with the conventional interior point method and the basic particle swarm optimization algorithm, and the effectiveness of the proposed algorithm is demonstrated.

Abstract

Normally speed control of a Single-Sided Linear Induction Motor (SLIM) by an indirect vector control scheme is difficult because the motor's parameters are time-dependent and the performance depends on various factors such as end effect, saturation, location of primary losses, and iron losses. Traditional PI current regulators are commonly used in vector regulators, but there is a tuning problem due to the oscillation of an operating point. This problem can be overcome by substituting an adaptive neuro-fuzzy-based current controller, and this controller improves the operation of a SLIM, such as its motor speed and thrust force. In this adaptive neuro-fuzzy controller, the ID and IQ errors and the error delay are inputs, and its outputs are Vds and Vqs, respectively. It is trained based on available values. A SLIM's dynamic modelling is implemented by dividing current (I) and flux-linkages into two terms. In these two terms, one is dependent on the end effect, and the other is independent of the end effect. The function of a Voltage Source Inverter (VSI)-fed indirect vector-controlled SLIM drive is simulated in MATLAB/Simulink, and its operation under various operating conditions is studied using an adaptive neuro-fuzzy current controller. These results are compared to a traditional P-I controller. The Pulse Width Modulation (PWM) technology that is used for controlling the VSI is called Space Vector Modulation (SVM).

Abstract

The purpose of this paper is to illustrate the dynamical response of speed using the design of a Fuzzy Logic Controller (FLC) to regulate the motor speed, while the load changes. Induction motor power control has become popular in recent years in high-performance drive systems. It is due to its amazing qualities, such as high-performance, a high energy factor, and significant toughness. The overall performance of the controller is estimated using MATLAB or Simulink software and a common Proportional Integral (PI) management technique. This work discusses the design and construction of a voltage supply inverter-based Space Vector Pulse Width Modulation (SVPWM) system for regulating the speed of an induction motor. This observation also incorporates a fuzzy controller into the SVPWM to maintain the motor speed constant even when the load varies. FLC is used to alter the pulse width of the Pulse Width Modulation (PWM) converter, which controls the motor pace. This paper describes the application of a rule-based Mamdani type FLC to a closed loop induction motor model.

Abstract

Solar power generation is one of the fastest-growing sources of renewable energy in the world. The economic benefits of technologies used to capture sunlight are increasing every year, expanding the opportunities for cleaner power generation. The global energy production model is changing from fossil fuels to renewable and nuclear energy. This paper provides a brief overview of the solar power generation system called Concentrated Solar Power (CSP), which is an emerging technology that is leading the way. The energy extracted from CSP technology is very clean, reliable, and environmentally friendly. This growth implies the complexity and size of systems and therefore requires an increase in maintenance tasks to ensure reliability, availability, maintainability, and security. This paper describes the various configurations of CSP, and the main causes and consequences of the CSP components are also analyzed.

Abstract

Energy management in home is gaining more attention as people try to use sustainable energy sources. This attempt to improve the use of infrastructure for energy production and distribution is expected to include smart grid systems. The incorporation of Internet of Things (IoT)-enabled smart devices into an ecosystem designed for maximum energy efficiency has been proposed for Smart Home Energy Management Systems (SHEMS). Smart homes are expensive, but smart plugs can change normal home devices relatively smart. This paper proposes a prototype design for a SHEMS it monitors and controls the energy consumption of smart devices to reduce the electricity bill and also detect energy theft.
