This paper presents the steady state analysis Quasi Switched Boost (QSB) DC-DC converter. QSB impedance network has only one inductor and one capacitor unlike Z-Source/Quasi-Z-Source which have two inductors and two capacitances in their impedance network but QSB impedance network has one more active switch, one more diode than Z-Source/Quasi-Z-Source impedance network. The DC voltage gain for ideal and non-ideal QSB DC-DC converter has been derived. Further the minimum inductance has been design to mark the boundary between (CCM) and Discontinuous Conduction Mode (DCM). The overall power loss has been calculated by considering the all parasitic of non-ideal Quasi-Switched Boost Dc-Dc converter. Further the efficiency analysis has been done by considering its overall power losses.

In this paper presence of pumped-storage unit is considered for understanding its effect over the optimal scheduling of multi-reservoir cascaded hydrothermal Plants. In Present scenario pumped storage units are becoming a valuable part of power system plants for energy and water conservation and accomplishing the need of high power demands. To maximize the water as fuel input in hydroelectric system pumped storage units are added with an advantage of operating in generating as well as pumping mode. Hydrothermal scheduling is an important aspect and is performed to minimize the operating cost of thermal power generation but considering a pumped storage unit other practical problems are also resolved. The purpose of this research is to implement a heuristic optimization technique for optimal economic scheduling of hydrothermal units considering a pumped storage unit. In proposed heuristic optimization technique, global best solution obtained from Particle Swarm Optimization (PSO) technique is further improved by applying different mutation strategies. The modified global best solutions are compared and most improved global best solution is chosen as a final solution and used for further iterations. The feasibility and efficiency of heuristic optimization technique be validated through a test system containing four hydro plants, three thermal plants and single pumped storage unit. The results demonstrate that the heuristic optimization technique can get a better solution in comparison with PSO technique.

The main objective of this paper is to understand the application of single phase grid tied photovoltaic inverter with reactive power control using three level voltage source inverter (VSI) configuration. For its implementation, a least complex grid synchronization approach was used for the generation of parallel and orthogonal components of the grid voltage in an efficient manner using various computing techniques to generate a synchronized current reference value in the current control loop. An improved H6 single-phase inverter topology ensures the elimination of the common-mode leakage current in the transformer-less photovoltaic grid-connected system. In addition this topology is also capable of withstanding the low input voltage similar to full-bridge inverter without causing any fault. The H6 inverter topology allows both unipolar Sinusoidal pulse width modulation (SINUSOIDAL PWM) as well as the bipolar (i.e. double frequency) SINUSOIDAL PWM control techniques for three-level output. Two additional switches are decoupled on the dc side for higher efficiency and convenient thermal design. Additionally, the unipolar-frequency SINUSOIDAL PWM facilitates higher frequency and low current ripples thereby reducing total harmonic distortion of the grid-connected current to a great extent.

Due to ever-increasing demand for power there arise a need for installation of higher efficiency generating stations. This problem of higher efficiency plants can be resolved by the combined cycle power plants which provide a high installation capacity and higher efficiencies; but the installation of newer generating stations affects the stability of grid. The behavior of combined cycle power plants is still a topic of research as none of the models developed yet have been successfully able describe its overall behavior. The following paper studies the behavior of combined cycle generator under various conditions using MATLAB/Simulink model.

Automating repetitive tasks in the industries increases the productivity; reduces the probability of error and maintain product quality. Traditional methods of mixing fixed quantities of different types of liquids and filling them in bottles involve manual mixing of the constituent components based on measurements and bottling of the mixture as desired. Manual handling of such tasks is time consuming; expensive and often lack consistency in product quality due to human errors. A Laboratory Prototype of a Programmable Logic Controller (PLC) based automated liquid mixing and bottle filling system is designed to automate the control and mixing of two different liquids in predefined proportion and filling the generated mixture in bottles to achieve quality control; reduce human intervention and improve productivity. The mixing system draws fluids from two storage tanks and mix them in a user selectable pre-defined proportion and stores the mixture in an overhead reservoir. The bottling system transfers the mixture from the overhead reservoir to conveyor fed empty bottles based on the user defined ladder logic. The developed laboratory prototype of the automated system has housekeeping features; which include high and low level liquid indicators; emergency alarm for warning the operator and automatic stop features etc.

Today's requirement is a system which is easier to control and simple in nature. Hence, it is desirable to reduce these higher order systems into the lower order system. A system with constant coefficient but uncertain within finite range is known as interval system. A lot of work has been presented in the previous years based on the nature inspired techniques. This paper aims to reduce linear continuous time interval system using mixed evolutionary techniques. The Routh approximation is used to obtain denominator of higher order system using the generalized routh table. The numerator of reduced order system is obtained using Big bang-Big crunch optimization algorithm by minimizing integral square error between original and reduced order system. Reduced order system retains the stability and steady state value of the higher order system. The numerical examples are illustrated and results are compared with the other well known methods.

To fulfill increasing green energy demand; installation of Photovoltaic solar farms are rapidly growing in various manners. PV solar farms feed active power during day time and become inactive in the night time. The increasing penetration level of Distributed Generations causes a rise in voltage at Point of Common Coupling (PCC) due to reverse power flow. To regulate voltage at PCC; utilities need to install voltage regulating devices like FACTs. The Voltage Source Converter is the heart of PV farm; including FACTs devices which is capable for reactive power compensation when there is no generation of PV farm. In this paper the utilization of PV solar farm for Grid voltage regulation at night time is proposed. An analysis and control in MATLAB/Simulink based environment is presented for different power flow conditions.

This paper contributes the optimal allocation of DSTATCOM (distribution static compensator) and DG (distributed generation) in radial distribution systems using exhaustive search method (ESM) to reduce the power loss and improvement of the voltage profile. The certain range of active and reactive powers have been injected simultaneously at each node by incorporating the corresponding size of DSTATCOMs and DGs respectively into the radial distribution system (RDS). On the basis of best reduction in power loss, the Size of DSTATCOM and DG are determined. Forward-Backward sweep load flow algorithm was used for the load flow solutions. The results obtained by proposed approach shows the optimal allocation and sizing of DSTATCOM and DG in RDS efficaciously reduces the power loss and improves the voltage profile. The IEEE-30bus RDS was used as a test system.

Voltage stability is considered as a very crucial factor for a stable and reliable operation of power system. In this paper an IEEE 30 bus system has been taken into account for maintaining the voltage profile at all the buses using Teaching Learning Based Optimization technique (TLBO) and Cuckoo Search Algorithm (CSA). Static Synchronous Compensator (STATCOM) and Static Synchronous Series Compensator (SSSC) are the FACTS devices which are employed for reactive power compensation. Optimal location of STATCOM is taken on the basis of voltage sensitivity indicator dV/dS. The bus which has highest value of voltage sensitivity indicator will be considered as most voltage sensitive bus (weak bus) and STATCOM will be placed at the weak buses. SSSC location will be taken on the basis of reactive power flow through the line and the line with the highest reactive power flow will be considered as the optimal line for placement of SSSC. TLBO and CSA is applied for getting optimal rating of voltage controlling parameters (STATCOM rating; SSSC rating; tap setting; Q-gen rating). Lastly a Comparision between TLBO and CSA has given for voltage stability point of view.
