In this paper, the steam unit of Yazd solar hybrid power plant has been modeled by using the design information of the power plant and using solar field and supplementary firing for generating additional work have been studied. Using solar field increases the net output work about 11.3% and decreases energy and exergy efficiencies about 7%. In the other hand, using supplementary firing, increases net output work up to 17.5% and in contrast, decrease energy and exergy efficiencies about 1 % and 5%, respectively. By using the results, it was found that using supplementary firing in comparison with using solar field generates more additional work and has less negative effect on energy and exergy efficiencies.

This paper focuses on choosing a suitable dynamic model for simulation of generation rate constraint (GRC) for load frequency control (LFC) of an interconnected realistic reheat thermal-thermal power system. Two different dynamic models for simulation of the GRC are investigated in details which are named as open loop and closed loop GRC models. These models have been used widely in literature interchangeably without any further description to the reason of selected modeling method and its suitability. This paper makes an attempt to help in choosing more effective and appropriate GRC structure pertained to reheat thermal units based on dynamic simulations to obtain optimal LFC. Reheat thermal units are examined with different GRC models. Then, integral of time multiplied squared error (ITSE) performance index is minimized by an improved particle swarm optimization (IPSO) algorithm to optimize proportional-integral-derivative (PID) controller parameters. All simulations are performed in MATLAB/SIMULINK environment. The results of eigenvalue analysis, dynamic simulations, and robustness analysis reveal the appropriate GRC modeling method for thermal units to attain high-performance and optimal LFC design.

Measuring the value of power generations productivity is one of the most important subjects associated with their efficiency. In this research, Malmquist index has been exploited for acquiring the productivity value of all combined cycle power generations in Iran between the years 2006 and 2012. Firstly, Malmquist index has been decomposed to four components namely as Efficiency changes, Technology changes, Pure efficiency changes and Scale efficiency changes. Then, bootstrap procedure is exploited for creating a sustainable estimation. The results illustrate that Malmquist index has decreased during the period of investigation. Furthermore, Malmquist index has been as a function of technology changes. In addition, efficiency changes have shown significant stability.

The three level inverters have been employed in industrial application from the previous time for converting DC voltage to AC voltage. Existence of harmonics in output voltage is the main problem in these constructions. THD is a very important factor to determine losses in the equipment's such as induction motor, transformers and etc. Hence the exact determination is important. In prior literature, to determine the amount of THD, approximate methods have been used. They have considered some limited low order harmonics. In this paper, to determine the exact amount of phase voltage THD (PVTHD), an exact procedure based on extracting formula is presented. The proposed methods consider all harmonic orders and can be utilized for each number of switching angles. In this paper, the new algorithm will have been employed to minimize phase voltage THD. The optimization angles are calculated by Intelligent Coefficient Multi Population Particle Swarm Optimization (ICMPPSO) algorithm. Finally, to show the effectiveness of the proposed methods, approximate and exact methods are compared. Simulation and programming are done in MATLAB software.

In this paper, a precise study of transient behavior of a 10 MW class wind turbine high temperature superconducting (HTS) synchronous generator is carried out. The proposed generator is analyzed through d-q equivalent circuit model and the transient specification of the generator is studied. Then, the performance of the generator under sudden three phase short circuit fault condition is simulated using finite element method. Due to using a stainless steel damper screening to protect the HTS wires from armature transient magnetic field, proper performance of the proposed generator during fault condition is deduced. This paper deals with the proper design of the proposed large scale HTS wind turbine generator which can withstand under system fault conditions without any dangerous problems.

Intermetallic alloys based on gamma titanium aluminide (γ-TiAl) are considered to be one of the best replacements for nickel-based super alloys (used in gas turbine blade) because of their unique set of properties. However the machinability of γ-TiAl is faced with restrictions and limitations due to the alloy's mechanical and metallurgical properties. Some of the most restricting properties include high temperature yield strength and wear resistance, even at elevated temperatures. Machining of γ-TiAl can also cause defects such as the formation of micro cracks on the machined surfaces. To explore the surface integrity of γ-TiAl under different cutting conditions, a series of machining experiments were carried out. High-speed and ultra-high-speed milling of γ-TiAl were examined under dry and minimum quantity lubrication (MQL) conditions. This research outlines the effects of cutting conditions on the surface integrity and Machining Affected Zone (MAZ). Two- and three-dimensional surface parameters were measured. In addition, the effects of machining parameters were studied using an analysis of variance (ANOVA). In addition, a mathematical model for the surface roughness measurements was developed in the present work. Likewise, other effects of surface alterations, including material pullout, deformations of the lamellae and micro cracks, were studied with optical microscopes (OM) and Scanning Electron Microscopes (SEM). Microhardness evaluation of the surface and subsurface indicated a significant difference between the surface and the bulk of the material (subsurface layers). X-ray diffraction analysis showed a phase transformation on the machined surfaces. Finally, the results of the present work are compared with previous works on machining of gamma titanium aluminide.

Islanding detection is a significant part of photovoltaic (PV) and distributed generation systems. In this paper a novel method for islanding detection of PV is proposed. The proposed passive method utilizes the negative sequence impedance and phase of inverter output current. PV array model and maximum power point tracking effect are considered. This method has a negligible non-detection zones and it is immune to the dynamics of power system like load and capacitor switching. 100kw Sunpower PV system, boost converter and inverter are modeled and simulated at MATLAB Simulink. The simulation results demonstrate the superiority of proposed method for robust islanding detection.

Preventive maintenance scheduling (PMS) of generating units is addressed as a long-term scheduling in power system studies which ensures a reliable supply of demand and economical operation of power systems. In this paper, a new structure of security-constrained PMS associated with a novel cost reduction index (CRI) is developed. CRI encourages generating units to be placed in a desirable situation while determining the most appropriate maintenance scheme and generation pattern. In this paper, a new linearized formulation for cost-based preventive maintenance scheduling associated with the CRI is presented. Here, the proposed framework is structured as mixed integer programming (MIP) problem and solved using CPLEX solver. This model would schedule maintenance scheme and commitment status of generating units while the system total cost including maintenance, operation and reserve expenditures is minimized. Values of energy and reserves over the scheduling time horizon are also determined simultaneously in this paper. The IEEE reliability test system (RTS) is utilized to demonstrate the effectiveness of the proposed structure.
