Challenges in the Electricity Market under a High Share of New Energy
Despite their clear advantages in low-carbon, environmentally friendly, and clean energy production, new energy sources—due to their uneven spatial output distribution and temporal mismatches between supply and demand—can give rise to a host of challenges in existing electricity market mechanisms, including price disappearance, price erosion, low efficiency in the utilization of distributed generation and storage, and poor interaction among demand-side resources.

What is the operating principle of a transformer?
The operating principle of a transformer is based on electromagnetic induction: when an alternating current is passed through the primary winding, it generates a time-varying magnetic field in the transformer’s iron core, which in turn induces an electromotive force in the secondary winding, thereby achieving voltage transformation. In this way, electrical appliances designed for different voltage levels can be adjusted to the appropriate voltage via a transformer and operate together seamlessly.

What kind of electricity market do we need under a high share of new energy?
In recent years, China has steadily intensified its efforts to develop new energy sources, actively aligning with the global Sustainable Development Goals and the dual carbon targets of peaking carbon emissions and achieving carbon neutrality. By the end of 2022, China’s installed capacity of renewable energy had reached 1.21 billion kilowatts, accounting for 47.3% of the country’s total power generation capacity. According to projections, under the assumption of achieving carbon neutrality by 2060, China’s electrification rate will reach approximately 70%, with the vast majority of electricity demand met by renewable energy. From a policy perspective, China has formulated and implemented a series of new-energy development policies, including the 14th Five-Year Plan for Renewable Energy Development, which have laid the foundation for the gradual increase in the share of new energy in the power system and facilitated the transformation of the power system—from quantitative changes to qualitative leaps—under the integration of high shares of new energy.
