The installation of renewable energy sources in island grids is focused on as a large part of island power generation whose power fluctuations should be compensated. A desalination system is given consideration as a controllable load. This paper proposes a model for such a desalination system, then estimates the controllable ranges under various constraints and evaluates the capacity for power fluctuation suppression. The model calculates the pressure, flow rate, and power consumption. The parameters in the model are fitted using tests with an experimental system. Next, the controllable ranges for power consumption under constraints involving the membrane or other factors are simulated using both tests and the model. The controllable ranges with the valve opening fixed are estimated to be 27% to 43% of the rated power. Finally, in order to evaluate transient response, step and ramp response tests and photovoltaic (PV) output suppression tests are performed. Most of the fluctuations in PV output are suppressed when PV output is within the controllable range. C⃝ 2017 Wiley Periodicals, Inc.

An energy management system for stand-alone microgrid consisting of a wind turbine (WT) generator, a diesel generator, an energy storage system (ESS), and a sea water desalination system is proposed in this paper. The coordinated control of the distributed generations and ESS is researched with two operation modes. Then, a real-time rolling horizon energy management method is presented based on hour-ahead wind speed forecast. The operation mode of the microgrid system and the reference output power of WT generator are determined according to the forecasted wind speed and state of charge of the ESS, which can achieve the goal of maximizing utilization of wind energy and minimizing utilization of diesel generator on the basis of system stable operation. The proposed energy management method has been tested on the real-time digital simulator system. The results clearly verify the effectiveness of the proposed method.Index Terms-Coordinated control, desalination system, energy management system (EMS), stand-alone microgrid.

“…The schematic diagram in this case is shown in Fig. 8 4) In the case that pressure surge is being generated and reaching: First, an assuming point is calculated with only consideration of the reaching pressure surge in the same way as case 3). Then, the next operating point is the point which is on the performance curve of the next pump rotating speed and the total head of the point is calculated by (5) whose H 0 and V 0 are the assuming point.…”

The use of a pump system for water supplies as the controllable load is proposed in order to compensate power fluctuations caused by renewable energy sources (RES) in an isolated island, and a control method of pump system power consumption is discussed. The dynamic model of the pump system is proposed taking into account the two step response of the power consumption caused by the pressure surge. Then, as the way to compensate the short cycle power fluctuations of RES by use of the pump system, deadbeat control with consideration of the pressure surge is proposed. Experimental results with deadbeat control show that power consumption can be settled more quickly compared with the case without deadbeat control. This shows that by use of deadbeat control, it is possible to compensate more rapid power fluctuations of RES.
