Abstract:Building local power station and integrating with the other power grid are the alternative solutions for power supply problems of the independent power grid in the remote areas. The best option should be adopted after a number of comprehensive comparisons combined with local energy resources and power grid construction conditions. Taking Ali Power Grid of Tibet for example,the solutions for power supply problems are analyzed and compared according to the energy resources,power grid status and development planning of the power grid. The recommended schemes are put forward and the related problems are summarized finally.
