The Economic Daily article points out that the key to balancing energy transition and energy security is to promote the deep integration of traditional energy and new energy sources. On the one hand, traditional energy and new energy are both alternative and auxiliary relationships. The key depends on how to promote an optimal combination of the two. New energy power generation requires “watching the sky and eating”, and large-scale grid connections are difficult. In the future, large-scale grid consumption of wind power and photovoltaics and stable operation of power grids will all be inseparable from peak-shifting matching of coal power. Especially under extreme weather and emergencies, fossil energy such as coal, oil and gas can play a supporting role. To this end, it is necessary to rationally lay out the construction of peak-shaving supporting power sources such as coal power, gas power, etc., to help the high-quality development of new energy sources.
