To construct a new power system with “new energy” as the main body, it is urgent to make more accurate prediction of new energy power and apply the prediction results to practical application from the perspective of overall power grid planning, so as to accept high proportion of new energy for the large power grid and make the power system operate securely and economiclly. Based on the actual demand of power dispatching as the guidance, the effectiveness of problem solving as the measurement standard, and the “open, efficient and practical” concept and mechanism innovation to achieve scientific and technological innovation, this paper proposes an innovation mechanism and implementation plan of the innovation platform for the accurate prediction of new energy power at multiple temporal and spatial scales. The paper discusses the top-level design, the basic idea of innovation mechanism, the architecture design and the main functions of innovation platform, and tries to explore a new path to improve the prediction level of new energy power by relying on technology and management innovation from the perspective of the power dispatchers.
