Based on the ultra high voltage （UHV） transmission technology, construction of the platform for nationwide optimum material deployment is the significant way to enhance the function and value of grid, which can promote the mode transformation of electric power, energy and economic. According to the large energy view, the innovative theory of electric power system planning with multi-regions, multi-materials and multi-dimensionalities considerations was proposed. The optimization of generation resources, water, environment and soil deployment was achieved by the optimum selection of the power generation scale, direction of cross-regional power flows between sending and receiving regions. The theory can promote the construction of energy comprehensive transmission system, well integrate and effectively utilize the large-scale renewable energy, and make the ecological environment better. Planning scheme of the State Grid Corporation of China （SGCC） had the achievements of exploitation layout of generations, accommodation of renewable energy, pattern of cross-regional power flows.
