The configuration of multistage forward osmosis power generation was introduced and electricity generation performance was improved effectively compared with the single-stage forward osmosis configuration. Simulation analysis is carried out on the configuration of multistage forward osmosis power generation and the effect of concentrated brine flow and preload pressure on the power output was analyzed. The results showed that the power output increased at first and then decreased with the increasing of concentrated brine flow or preload pressure and there existed a highest value. For different energy recovery efficiency, optimization model with the maximum the power output of 100 m2 osmotic membrane as the objective and with concentrated brine flow and preload pressure as the decision variables was established. As a result, there were different optimum solutions concentrated brine flow and preload pressure for different power recovery. It showed that concentrated brine flow decreased and preload pressure increased with the increasing of power recovery.
