Power grid morphological positioning and assessment method in the energy revolution

The energy revolution will affect the development and utilization of energy, the production and distribution of electricity, and then has profound impacts on the function and form of the power grid. In this paper, to analyze the impacts of energy revolution in China, we generator of electric system planning (GESP) model to simulate energy structures and layouts that simulate different scenarios. Then we improve the calculation methods of the index scores and weights to improve the TOPSIS evaluation method, composing a comprehensive assessment system of TOPSIS-AHP-Entropy method. Furthermore, we construct a multi-dimensional evaluation index system that includes economics, technology, and environmental protection. The assessment results of two scenarios demonstrate, in the context of the energy revolution, that the Reinforcement scenario with large-scale renewable energy, has much better benefits, which requires the grid stronger, more efficient, cleaner. In the new energy revolution, there are four main changes of the morphological positioning and functional patterns of future power grid.
