Design and Implementation of Hybrid Pico-Hydro – Photovoltaic (PV) Solar Power Plant in Massy-Gahuku LLG

Hydro-Electricity and Solar Power are environmentally friendly renewable sources of energy that utilize the potential energy from dammed water and the sun respectively to generate electricity. In this paper is reported a new design and implementation of combining solar and hydro-electric power. The turbine and gearbox system used in this design is fabricated from scarp parts of used appliances. The hydro head of the Pico-Hydro plant commissioned was 5m which accumulated a hydraulic potency of the stream of about 5.886kW. The prime mover of the generator consisted of a modified crossflow turbine that is coupled with a gearbox to amplify the rpm of the system. A 500W synchronous generator was driven by the prime mover to generate raw phase shifted AC power. This raw power was rectified with a 25 A full wave rectifier and used in conjunction with 12 V 400 AH deep cycle battery bank system to supply power to a newly furnished double storey house. The generator output through the full wave rectifier is connected to a load controller for optimal charge efficiency. The load controller is connected to the battery bank through a Programmable Logic Controller (PLC). The PLC activates a dummy resistive hot water element when the battery bank is fully charged. The Arduino GSM module monitors the entire process and automatically sends notification via a SIM interface to the system administrator notifying the system administrator of the on/off state of the heating element.

The novel modified Elman neural network (NN) controlled permanent magnet synchronous generator (PMSG) system, which is directly driven by a permanent magnet synchronous motor (PMSM) based on wind turbine emulator, is proposed to control output of rectifier (AC/DC power converter) and inverter (DC/AC power converter) in this study. First, a closed loop PMSM drive control based on wind turbine emulator is designed to generate power for the PMSG system according to different wind speeds. Then, the rotor speed of the PMSG, the voltage, and current of the power converter are detected simultaneously to yield better power output of the converter. Because the PMSG system is the nonlinear and time-varying system, two sets online trained modified Elman NN controllers are developed for the tracking controllers of DC bus power and AC power to improve output performance of rectifier and inverter. Finally, experimental results are verified to show the effectiveness of the proposed control scheme.

The combination of a fuel cell and batteries has promising potential for powering autonomous vehicles. The MUN Explorer Autonomous Underwater Vehicle (AUV) is built to do mapping-type missions of seabeds as well as survey missions. These missions require a great deal of power to reach underwater depths (i.e., 3000 meters). The MUN Explorer uses 11 rechargeable Lithium-ion (Li-ion) batteries as the main power source with a total capacity of 14.6 kWh to 17.952 kWh, and the vehicle can run for 10 hours. The drawbacks of operating the existing power system of the MUN Explorer, which was done by the researcher at the Holyrood management facility, include mobilization costs, logistics and transport, and facility access, all of which should be taken into consideration. Recharging the batteries for at least 8 hours is also very challenging and time consuming. To overcome these challenges and run the MUN Explorer for a long time, it is essential to integrate a fuel cell into an existing power system (i.e., battery bank). The integration of the fuel cell not only will increase the system power, but will also reduce the number of batteries needed as suggested by HOMER software. In this paper, an integrated fuel cell is designed to be added into the MUN Explorer AUV along with a battery bank system to increase its power system. The system sizing is performed using HOMER software. The results from HOMER software show that a 1-kW fuel cell and 8 Li-ion batteries can increase the power system capacity to 68 kWh. The dynamic model is then built in MATLAB/Simulink environment to provide a better understanding of the system behavior. The 1-kW fuel cell is connected to a DC/DC Boost Converter to increase the output voltage from 24 V to 48 V as required by the battery and DC motor. A hydrogen gas tank is also included in the model. The advantage of installing the hydrogen and oxygen tanks beside the batteries is that it helps the buoyancy force in underwater depths. The design of this system is based on MUN Explorer data sheets and system dynamic simulation results.
