Development Path of Future Power Grid with High Proportion of Renewable Energy in the Context of Electricity Spot Market

The world is striving for a diversified, clean, efficient and market-oriented chain for power supply and consumption. In China, the development of clean energy, the reform of power market and the progress of Energy Internet technology make the energy and power industry in an unprecedented period of transformation. Considering that the development of power grids is a realistic problem-oriented theme, the development problems of power supply, grid and demand side in the electricity spot market is analyzed. On this basis, the development goals of the future power grid and the research direction are summarized respectively, with the future power grid development roadmap constructed. This work aims to clarify the relationship of each link of power grid development, and further promote the transformation and development of power grids to Energy Internet.
