The application of integrated energy use in the agriculture sector It is presented in the form of using renewable energy from solar energy to produce electricity to use in conjunction with other sources of electricity such as generators or electric power systems. Using solar panels or solar cells the size and number of panels does not exceed 300 watts 4 panels and the electrical system of the electrical system. Supply electric power to the water pump size does not exceed the rating of 1500 watts 220 volts. Solar power supply systems alone may be affected by weather conditions or electrical power supplies. Including the quality of electricity obtained from solar energy and will result in the water pump not working efficiently. Therefore the application of solar energy by using a power supply system from 2 sources by using a hybrid inverter device to select the power supply from the solar cell is the main power and the power supply from the memory system is the backup power. Therefore a research project on the application of solar water pumps in a mixed system for agriculture is proposed to increase the efficiency of electric power distribution. This application of solar water pump hybrid system for agriculture when used with water pumps can normally help to save electricity and can also use solar energy instead of using electricity to pump water. Let the water pump and can work efficiently.

This research project presents about wind turbine simulation for connected single phase grid system using hysteresis current control technique to generate PWM signals for controlling a single-phase voltage source inverter. The simulation system presented here uses the program. MATLAB/Simulink in the simulation of the wind turbine connected to the shaft of a three-phase permanent magnet generator is produced by alternating current through the full bridge rectifier circuit. Then the power supply is applied to the single-phase inverter circuit which is connected to the single-phase autotransformer to power transfer to the single-phase grid system. The simulation results confirm the validity of the proposed system with satisfaction under various conditions.

This paper presents an efficient algorithm for optimization of radial distribution systems by a feeder reconfiguration to balance feeder loads and eliminate overload conditions. The system load-balancing index is used to determine the loading conditions of the system and maximum system loading capacity. The index value has to be minimum in the optimal feeder reconfiguration of load balancing. A method based on Tabu search algorithm The Tabu search algorithm is employed to search for the optimal feeder reconfiguration. Simulation results for a radial 69-bus system with reconfiguration and capacitors placement. The study results show that the distribution system with capacitor placement and optimal on/off patterns of the switches feeders reconfiguration can be load balancing in distribution systems.

This thesis is duplicated of the controlled of the AC. Three Phase Generator with case study and analyze of the characteristic of generator in various operating conditions. By the model works of the actual use in establishment generator this is using generator for backup electricity from main feeder. We have the functional testing of start or stop for check store the characteristics in different conditions at that time. Load distributing of generator for check store parameters. The parallelization of generator into the system in case of emergency while the failure of the mains system. The degradation of generator off the system when main is back to normal or the emergency stops of generator in case of accident during the operation.
