Problems solved by technology

The large-scale development of intermittent new energy such as wind power and photovoltaics faces three major technical problems: first, it has randomness and volatility, and the characteristics of power generation need to be improved; second, it is difficult to effectively predict, dispatch and control, and the coordination performance of source and network needs to be improved; third, The geographical characteristics of resources are obvious, and the demand is reversed, and the problem of effective allocation of resources needs to be solved

These three major problems have become the bottleneck restricting the development of my country's new energy. If they cannot be effectively resolved, it will seriously affect the realization of my country's new energy development goals.
