In the paper, a new type of wind-solar hybrid system was proposed, in which multiple small wind turbines took the place of a bigger one. The electricity performance of the multi-turbine wind-solar hybrid system was studied in comparison with the traditional system. Two types of wind-solar hybrid system with the same capacity were set up in Tianjin, and the power output of the two systems were measured and simulated by the TRNSYS software. The results showed that, at low wind speed, the multi-turbine wind-solar hybrid system has more power production than the reference system. The simulated results agreed well with the experiment results. Then, the electricity performance of the multi-turbine wind-solar hybrid system was studied under various climates in China by the TRNSYS. The simulation results showed that the power output of the wind turbines in multi-turbine wind-solar hybrid system increases by 18.69%, 31.24% and 53.79%, when used in Shenyang, shanghai and Guangzhou, respectively, compared with the reference system.
