Dynamic Modeling of Autonomous Wind–diesel system with Fixed-speed Wind Turbine Najafi Hamid Reza; Dastyar Farshad
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 2: August 2012
Publisher : Institute of Advanced Engineering and Science

Wind turbines have often connected to small power systems, operating in parallel to diesel generators, as is typically the case in autonomous wind–diesel installations or small island systems with high wind potential. Hence, the modeling and analysis of the dynamic behavior of wind–diesel power systems in presence of wind power will be important. In this paper, the system under study is modeled by a set of dynamic and algebraic equations (DAE). Dynamic behavior of a wind-diesel system is investigated by the proposed dynamic model. Wind-diesel system consists of wind turbines that are connected to synchronous diesel generator via short transmission line with local load. Dynamic stability of autonomous wind–diesel systems are discussed with emphasis on the eigenvalue analysis and the effective parameters on system stability. In this regards, saddle node bifurcation and hopf bifurcation are also investigated.

High costs of installation and maintenance as a result of storage units discourage the use of solar Photovoltaic system for power generation. To reduce these costs, Solar PV systems can be installed without storage units alongside conventional power generation systems. Such that the Solar systems cater for the daytime loads while the conventional generation system caters for loads at other times. This research paper explored the potential of installing Stand-Alone solar PV systems without storage to satisfy the daytime load demand of the Canaanland community. The load profile analysis of the Canaanland community was carried out from load consumption data and the solar power plants were designed based on this analysis. Simulation was carried out using the PV Syst 6.43 software and the result from the design was analyzed. The study revealed that the solar power plant will serve the daytime load of the community during the period of 10:30am-4:30pm daily satisfying the peak and base loads (5.16MW and 0.78MW) of the Canaanland community respectively.

Smart Power Transmission System Using FACTS Device Qazi Waqar Ali; Azzam ul Asar
International Journal of Applied Power Engineering (IJAPE) Vol 2, No 2: August 2013
Publisher : Institute of Advanced Engineering and Science

Making of smart grids puts mounting pressure on the nation’s aging electric power transmission system. Just planting additional towers and stringing more line won’t practice the nation’s electric power transmission infrastructure to meet up the energy challenges ahead. Smart grids stand geared up to play a much larger role in the energy equation for reduction of transmission line losses. The FACTS controllers come out with the capability of enhancing transmission system control, reliability, and operation. This paper will discuss and express how Static Synchronous Compensator (STATCOM) has effectively been applied to power system for efficiently regulating system voltage and thus increase system load ability. This paper investigates the effects of (STATCOM) on voltage stability of a power system at different positions.The simulation analysis of this paper can be used as guideline for power industry. The study is thereby simulated using the MATLAB/SIMULINK software and simulation results show that STATCOM is effective in midpoint voltage regulation on transmission line. In this paper comparison is also performed between STATCOM and SVC under fault condition and it is proved that STATCOM have the capacity to provide more capacitive power for the period of a fault than SVC.

A Fast Strategy to determine the Physical and Electrical Parameters of Photovoltaic Silicon Cell El Hadi Chahid; Mohammed Idali Oumhand; Abdessamad Malaoui
International Journal of Applied Power Engineering (IJAPE) Vol 6, No 2: August 2017
Publisher : Institute of Advanced Engineering and Science

This paper proposes a fast strategy to extract and exploit the electrical parameters of photovoltaic cell using the double-diode model. The polycrystalline silicon (poly-Si) junction is chosen in this work due to the importance of its proprieties in industrial and economic fields. The proposed method to extract the solar cell electrical parameters contains two steps. The first is based on the graphical adjustments to choose the initial values of these parameters, and the second is numerical, using Modified Newton-Raphson’s algorithm. The obtained parameters extractions values are compared to the others methods and give a considerable agreement. Furthermore, we have developed a complementary analytical method to deduce both the minority’s carrier’s lifetime and the diffusion lengths through the diffusion and recombination current densities. The found values of these parameters are precisely comparable with theoretical models, and give very useful informations on the intrinsic quality of the studied cell.

Harmonic Voltage Distortions in Power Systems Due to Non Linear Loads Aryan Kaushik; Jyothi Varanasi
International Journal of Applied Power Engineering (IJAPE) Vol 3, No 1: April 2014
Publisher : Institute of Advanced Engineering and Science

Harmonics are found to have deleterious effects on power system equipments including transformers, capacitor banks, rotating machines, switchgears and protective relays. Transformers, motors and switchgears may experience increased losses and excessive heating. Shunt filters are effective in minimizing voltage distortions. This paper describes the voltage distortions generated by non linear loads. The harmonic specifications such as harmonic factor, characteristic harmonic and non-characteristic harmonic are considered while explaining the paper. ‘MiPower’ software is used to compute the harmonic distortions in a sample power system. Accurate harmonic models are established for a non linear load. To reduce the harmonic voltages impressed upon specific parts of the sample power system, passive filters are installed at two buses. With the implementation of a passive filter at the bus with non linear load, the harmonics are greatly reduced. For the specified power system, at all the buses the total harmonic distortion has been evaluated.

International Journal of Applied Power Engineering (IJAPE) Vol 9, No 1: April 2020
Publisher : Institute of Advanced Engineering and Science

A modified adaptive neuro-fuzzy inference system sliding mode control (ANFIS-SMC) by using two-level space vector pulse width modulation (SVPWM) for doubly fed induction generator (DFIG) is proposed in this article. ANFIS-SMC with SVPWM strategy improves the basic SMC performances, which features low stator active and reactive power and also minimize the total distortion harmonic (THD) of stator current. The computer simulation results, in Matlab, demonstrate the effectiveness of the proposed control strategy which improves the performance of the DFIG.

Experimental Evaluation and Validation of Random Pulse Position Pulse Width Modulation for Industrial Drives P. Arulkumar; N. P. Subramaniam
International Journal of Applied Power Engineering (IJAPE) Vol 4, No 1: April 2015
Publisher : Institute of Advanced Engineering and Science

In industrial drives, random pulse width modulation (RPWM) is triumph for transferring of harmonic power from the detached spectrum of the output voltage to the unremitting spectrum, and offers the merits viz. The operation is free from an unpleasant acoustic noise and a mechanical vibration. The main objective of this paper is providing a comprehensive investigation of performance of random pulse position pulse width modulation (RPPPWM) for a three-phase voltage source inverter (VSI) fed induction motor drives. RPPWM scheme randomly varies the pulse position in every switching cycle, where the idea is inducing the random characteristics in the PWM pulses at fixed switching frequency. The competence in spreading the harmonic power of sinusoidal PWM (SPWM), random carrier PWM (RCPWM) and the RPPWM are compared using simulation. The results are corroborated through the prototype VSI designed. The developed RPPPWM based on a SPARTAN-6 FPGA (XC6SLX45) device, disperses the acoustic switching noise spectra of an induction motor drive

Publisher : Institute of Advanced Engineering and Science

In this paper chaotic predator-prey brain storm optimization (CPB) algorithm is proposed to solve optimal reactive power problem. In this work predator-prey brain storm optimization position cluster centers to perform as predators, consequently it will move towards better and better positions, while the remaining ideas perform as preys; hence get away from their adjacent predators. In the projected CPB algorithm chaotic theory has been applied in the modeling of the algorithm. In the proposed algorithm main properties of chaotic such as ergodicity and irregularity used to make the algorithm to jump out of the local optimum as well as to determine optimal parameters CPB algorithm has been tested in standard IEEE 57 bus test system and simulation results show the projected algorithm reduced the real power loss considerably.

International Journal of Applied Power Engineering (IJAPE) Vol 4, No 3: December 2015
Publisher : Institute of Advanced Engineering and Science

The paper presents an improved predictive direct control of a variable speed. The method is based on finite states space model of the converter. The proposed control method selects the optimal switching state of (Indirect Converter with and without energy storage for rectified and inverter) that minimizes the error between orthogonal torque, fluxs, and the reactive power components predictions to their computed values for all different voltage vectors. The optimal voltage vector that minimizes a cost function is then applied to the output of the power converter. The main aim of this paper is to propose an online optimization of the weighting factors by the Particle Swarm Optimization (PSO) approach well known by its robustness and fast convergence to the global optimum. Simulation results show that PSO strategy is very efficient to design accurately and quickly these weighting factors.
