Scenery big base construction, need to pay attention to what?

Abstract from High-quality energy development

   "At present, the first batch of scenery bases have begun construction, and the planning of the second batch of bases has also landed." In the beginning of the development of wind power and photovoltaic, in fact, we have done a similar round of "big base" development, and built a large project such as "Three Gorges wind power". What is the difference between the current scenery and the original big base? Looking back, what are the lessons to be learned?" In the "New power system wind bright base planning and construction seminar" held recently, Li Qionghui, director of the New energy and Statistics Institute of the National Grid Energy Research Institute, threw out the question, which triggered the resonance and thinking of the participants.

    In October 2021, China formally proposed at the 15th Conference of the Parties to the United Nations Convention on Biological Diversity that it will vigorously develop renewable energy and accelerate the planning and construction of large-scale wind power photovoltaic base projects in desert, Gobi and desert areas. How will this change the power system in the future? At this stage, what problems should be paid attention to in the construction of large bases?

     "There is no guarantee of consumption of electricity, no matter how large the base is built, it is meaningless."

    "At the beginning of the development of new energy, the main goal of the construction of the ''big base'' is to cultivate the industry. Therefore, most projects are in the construction process and even after the completion of the gradual consideration of the problem of consumption, and there is no clear transmission channel in the pre-planning, the subsequent problem of difficult consumption is very prominent." Li Qionghui said that today, the construction of "scenery big base" must learn lessons in the development model and consumption model, "Different from the previous positioning, this round of big base construction is carrying the need to achieve the goal of carbon peak carbon neutrality." It emphasizes not only the scale, but also the consumption and utilization. Without the guarantee of consumption of electricity, it is meaningless to build a large base, which cannot support the realization of the goal of carbon peak carbon neutrality."

    Chi Yongning, chief engineer of the new energy center of the China Electric Power Research Institute, said that at present, the national high voltage direct current transmission capacity is about 450 million kilowatts, but by 2030, only the new installed capacity of the scenery base will reach about 550 million kilowatts. "Take Inner Mongolia, the key area of the construction of a large base, for example, although the local can absorb part of the electricity, but more electricity must be sent, now to the North of the main region, the follow-up may also be sent to central or eastern China. On the whole, there is definitely a demand for UHV construction, and whether it will bring new problems of wind and light abandonment mainly depends on whether the construction of the delivery channel can be completed simultaneously with the construction of the base."
