Activity review
On the afternoon of March 23, 2023, the 30th Technical Seminar of China Energy Modeling Forum (CEMF) and the 6th Carbon Neutral Academic Salon were held at the Carbon Neutral Research Institute of Tsinghua University. This symposium invited Professor Michael Davidson, Assistant Professor of the Department of Mechanical and Aeronautical Engineering and the School of Global Policy and Strategy at the University of California, San Diego, to give a keynote speech.". Cao Jing, Associate Professor of the Department of Economics, Tsinghua University School of Economics and Management, Chen Ling, Director of the Industrial Development and Environmental Governance Research Center of Tsinghua University, Zhu Lei, Professor of the School of Economics and Management of Beihang University, and Zhang Xingping, Professor of the School of Economics and Management of North China Electric Power University were invited to attend the seminar and discussed Participate in the exchange. The seminar was presided over by Zhang Da, an associate professor at the Institute of Energy, Environment and Economics of Tsinghua University and assistant director of the Center for Climate Governance and Carbon Finance of the Carbon Neutral Research Institute of Tsinghua University. Experts and scholars carried out in-depth discussions around the field of power system research. They discussed the resource adequacy problem in the process of energy transformation of China's power system. The seminar was co-hosted by the Climate Governance and Carbon Finance Center of the Carbon Neutral Research Institute of Tsinghua University, the China Energy Modeling Forum (CEMF), and the Institute of Energy, Environment and Economics of Tsinghua University, and undertaken by CIDEG.
The 30th CEMF Technical Seminar and the 6th Carbon Neutral Academic Salon
Professor Dai Weisen first shared the research team's cooperation project, taking the Northeast Power Grid as an example, and analyzed the influencing factors that may lead to the "power cut" event in the Northeast in the winter of 2021. He believes that the research results show that the main reasons for the power shortage in Northeast China include: the post-epidemic economic recovery has led to a sharp increase in electricity demand and increased in coal prices. However, the split between the coal market and the electricity market has resulted in the cost price of thermal coal being higher than the market price of electricity, and some coal power plants have stopped generating electricity because they cannot make ends meet. In addition, the long-term agreement between the Northeast Power Grid and the Northern Power Grid stipulates that the Northeast Power Grid must transmit a certain amount of electricity to the Northern Power Grid, which further exacerbates the power supply shortage in the Northeast itself. In addition, Professor Dai Weisen believes that the analysis of wind power output data during the period of "power rationing" shows that the phenomenon of insufficient wind power output in Northeast China appeared in the later stage of "power rationing", which is not the cause of the severe power shortage in Northeast China. Indeed, in the latter part of the incident, it became more difficult to restore the balance between power supply and demand in Northeast China.

Professor Davidson also predicted the operation of the Northeast Power Grid under different scenarios in the winter of 2022 and 2023, and said that the extreme weather conditions caused the increase in electricity demand, the decline in renewable energy output, and the increase in energy prices led to the reduction of thermal power capacity and priority for export Electricity will aggravate local power shortages and other issues that will threaten the adequacy of resources in the Northeast. Therefore, Professor Davidson said that China needs to accelerate market-oriented reforms in the process of low-carbon transformation of the power system, conduct regular forward-looking scenario analysis to ensure sufficient power supply, and strengthen the power system and market flexibility.
In the expert discussion session, Associate Professor Cao Jing, Department of Economics, School of Economics and Management, Tsinghua University; Lei, Professor Zhang Xingping and Professor Dai Weisen from the School of Economics and Management of North China Electric Power University discussed the status quo of China's power system, future technology scenarios, model methodology, and the importance of power system resource adequacy in China's gradual transition to renewable energy was discussed in depth. Experts agree that resource adequacy is an urgent problem facing China's energy and power systems, and it is necessary to actively seek solutions.
