AbstractIn the current research, a stand-alone irrigation system has been designed using the drip irrigation (DI) methodand powered by hybrid renewable energy systems (wind turbine and photovoltaics). The system was implemented in the area of a strawberry plantation in Garut, Indonesia. The drip irrigation system was designed using a pumping system where the water flow rate to the plant was controlled around 1.5 l/day with an operating planting time of 1.58 hours/day. Based on the calculation of the irrigation piping system, pressure in the system must be maintained at the set point 1.2 bars to produce the desired flow rate. A proportional Controller (Kp) was used for controlling the opening of the control valve. Based on the controller’s response, the system could reach the set point at 24.95 seconds, with a maximum overshoot of only 0.0231 bars, and has no steady-state error. Energy for the pumping irrigation system was supplied by photovoltaics (PV) and wind turbine (WT). Based on the irrigation water demand per day, the total energy demand for this irrigation pumping system was 1743 Wh. The hybrid renewable system was designed by a combination of ten PV cells and a single wind turbine. The energy generated by PV and WT was 8705 Wh/day; therefore, the power system was feasible to be implemented because it was still 3.3 times larger than the requirement. Reference
