Study and application of the wind power on the tall building rooftops in large cities

There are different technical limitations on the utilization of the wind power (WP) in large cities. But the wind speeds on the tall building rooftops are stronger, the wind power on the tall building rooftops (RWP) presents another usages of wind power in the new energy area. This article mainly focuses on the characteristics and advantages of RWP, and analyses the feasibilities of the usages of the roof wind energy and finds out a new way to develop the wind energy to generate electricity. Because the speeds, directions and characteristics are always changing, the Geometric Progression model is put forward to adapt to the unstable power. Then this model is used to deal with the conflicting power between the roof wind power and the electric power, and the conclusion is satisfying.
