Abstract Photovoltaic generation, which is an important application way of solar, is attracting more and more attention. However, its output power is intermittent with different environment. A backup power source is necessary. Grid is chosen to be the backup power source in this paper, and a hybrid photovoltaic/Grid power system is proposed. It is composed of solar cells, grid, a DC-DC converter, and a power factor correction. In order to enable these two source work coordinate, it is necessary to manage the power. The key point of power management is to control the system to work in proper mode, according to different situation of solar cell and load. A 2kW hybrid system is built in the lab. The experimental results verified the proposed power structure and energy management.

Key words： Solar sell power factor correction DC-DC converter energy management
