要約(英語): Installation of renewable energy sources in island grids is focused on as large expense of island power generation and their power fluctuations should be conpensated. Desalination system is being focused on as a controllable load. This paper proposes a model for the desalination system, estimates controllable ranges under restrictions and evaluates the ability to suppress the power fluctuations. The model calculates the pressure, flow and power consumption. Parameters of the model are fitted by tests with an experimental system. Next, controllable ranges of power consumption under restrictions of the membrane etc. are estimated both by tests and by the model. Controllable ranges with fixed valve openness are estimated as 27 to 43 percent of its rated power. Finally, to evaluate transient response, step and ramp response tests and photovoltaic (PV) output suppression tests are conducted. Most of the fluctuations of PV output are suppressed when PV output is within the controllable range.
