Projects among the project group exchange the massive material information and energy and influent mutually between projects, more participants and more intense in conflicts of interest. all these result in a large number of management interface and more complex levels of management increasing the difficulty of program management.
According to the flexible management of the project team of the indicators of the specific circumstances of the standards and content, and various levels is decided by the literature material and the experience of managers.

Introduction Energy is an important material basis for social and economic development,as a clean and convenient energy form,energy is the lifeline of the national economy[1].Power grid safe, economical and stable operation not only directly related to people's lives, also an important issue related to the social stability and national security.In recent years, under the leadership of the China State Grid Corp, the power system has developed into a large-scale interconnected system,a system with large capacity unit centralized power, ultra transmission characteristics of high voltage long distance; at the same time, the development of power grid is also faced with multiple pressure shortage, environmental protection, operation safety and reliability.In this environment, many countries in the world have started looking for both environmental protection and high efficiency, flexible way of generating -- DG(Distributed Generation).Distributed generation has the advantage of dispersed, flexible
