Abstract: The world's large dependency on conventional energy sources has not only posed a threat to the environment but also they are non-renewable. Therefore, a huge interest is put upon renewable sources of energy. Amongst them, solar technology has become a rapid growing industry for power generation. This paper briefly reviews the technological challenges of maximum power point (MPP) tracking of photovoltaic (PV) energy obtained from solar cells. The paper describes the evolution of several MPP techniques that are popular commercially and presents their basic working, utilisation ability in different scenarios, cost of implementation and new research performed to find better techniques. The study also includes incorporation of soft computing in solar MPP tracking. It is observed that, the MPP tracking techniques are rapidly evolving from simple to complex methods, as per the demands..........

Abstract: The proposed operational strategy is mainly focused on using an appropriate energy management and control strategies toimprove the operation of an islanded microgrid, formed by photovoltaic (PV) system, SMES-batteries and loads. This control strategy is to achieve decentralized power management of a PV/battery/Fuel cell hybrid unit in a droop-controlled islanded microgrid. In contrast to the common approach of controlling the PV unit as a current source, in the proposed strategy, the PV unit is controlled as a voltage source that follows a multi-segment adaptive powercharacteristic curve. The proposed power characteristics, of the hybrid unit and of the whole microgrid.......

Abstract: DC-DC Power Converters are employed in order to transform an unregulated DC voltage input (i.e. a voltage that possibly contains ripples and disturbances) in a regulated output voltage. On citing an example a DC-DC power converter can transform an unregulated (i.e. distorted) 9V input voltage in a regulated (i.e. ―clean‖) voltage of 12V at the output. Some DC-DC power converters have a fixed output reference and ensure that such voltage is always delivered, no matter what the input is; some others can have a variable output reference, which can be therefore set depending on the current need of the device the power converter is used in. The converter discussed in this work belongs to this second category. In particular, the converter is able to deliver output voltages both higher as well as lower than (or even equal to) the input voltage; this is why it is referred to as a ―buck-boost‖ (or ―step-up/step-down‖) power converter..

Abstract: The design procedure of micro-hydro power plant was implemented by Matlab Simulink computer program to calculate all the power plant parameters. The choice of turbine type was depending mainly on the site head and rate of flow. The turbine power and speed were directly proportional with the site head, but there were specific points for maximum turbine power and speed with the variation of the site water flow rate. The head losses in the penstock could range from 5 to 10 percent of the gross head, depending on the length of the penstock, quantity of water flow rate and its velocity, intake channel, trash rack specifications and gate valves type. The turbine efficiency could range from 80 to 95 percent depending on the turbine type. The choice of generator power and its specifications depends on the turbine output power and speed. The generator efficiency was about 90 percent.......

Abstract: This paper presents the analysis of compensated ac transmission lines under two different forms of compensations: series and shunt compensations. The Thevenin equivalent circuit of each was drawn and analyzed. The result shows that at a transmission angle (that is δ) of 180o, a shunt compensated line would be able to deliver an active power double the amount achievable under series compensation.

Keywords: shunt compensation, series compensation, active power, Thevenin equivalent circuits, and transmission angle

Abstract: The tourism sector is the backbone of the economy in Malang Regency, especially in Batu City. The development of tourism in the region initially is in the form of agro tourism, which includes apple orchards, strawberries, and various tubers.Many tourists, both outside the region and local residents, do not know the location of educational tourism in Malang. Previously, they know such information from the recommendation of friends or by verbal news. In addition, there is only tourist information on the location of the indicated area. Therefore, a system that can help to know the location of the tour that can be accessed anywhere and anytime based on economic ability and tourist location is required. Objects in this study include educational tours that are more aimed at children with early school age, namely when entering elementary school. One of the methods proposed by this research is using...........

Abstract: The proposed series Z-source matrix converter topology investigates the output voltage, the inrush current and the voltage across the capacitor between the stages. In this paper, that idea is implemented on a three-phase to three phase indirect matrix converter. This z-source matrix converter is connected across the inverter and rectifier circuit for amplifying the voltage gain. The proposed converter is designed on the principle of ultra sparse technology in order to rebate the number of semiconductor switches. The boosting capability of this converter can be enhanced by an optimal PWM technique and by reducing the switching losses. The comparative analysis is performed between series and cascaded Z-source matrix converter topologies can be applied for wind energy conversion system...........

Abstract: The speed regulation from zero to limit value in direct current electric drives is done by means of increasing armature voltage from zero to nominal value. It is called the speed regulation in first zone. The speed regulation above the limit value is called the speed regulation in second zone. It is done by reduction of excitation winding voltage under the nominal value. In this paper, we study an algorithm design of common control of rotor rotation speed in first and second zones..

Abstract: The International Maritime organization (IMO) sets regulations for marine vessels to insure safety and prompt response to various demands. when it comes to an unmanned vessel it has been done with PID controllers in which it operates enormous variables. In order to ease the operation of an unmanned vessel, we used an Arduino Uno Controller to monitoring and transferring the data from shore base station. The function of this controller is giving the particular location of the vessel and a real stream image of the situation surrounding the vessel. For that it's necessary a GPS,GSM & WEBCAM in which an Arduino Controller control and operate the system (input/output),the remote is giving a signal to the controller to ON the motor and adjust the particular degree to move at that exact time the signal will be given to GPS System and further to GSM and the location and real image of the vessel will be recorded,the project ensures an accurately and real response to dangerous situations like piracy or oil leakage/spill as a surveillance method..
