Enlightenment of EU power market integration: standardization should be considered first in the design of pilot market

recently, China's national development and Reform Commission and the Energy Administration jointly issued the notice on carrying out pilot work of power spot market construction. The first eight provinces and regions have become the pilot market of electric power spot, which is a big step in the progress of electric power reform. In the long run, gradually expanding the power balance area on the basis of the provincial market and forming a larger regional power market is a better choice to further optimize the allocation of resources, and it is also the latest trend of the development of the world power market

from a global perspective, in recent years, the United States, Europe and many other regions have strengthened the integration of power market and system operation. The idea is to connect geographically dispersed markets, power companies and transmission system operators. From the perspective of practical experience, it has been increasingly recognized by countries around the world to bring benefits by improving the integration of power markets and system operations across geographical regions. Taking Europe as an example, a study shows that the benefits of EU power market integration can reach 12.5 billion euros to 40 billion euros per year by 2030

when the system is operated in a larger region (such as among EU countries), the operational risk is concentrated: the demand for operational reserve is determined by the situation of cross regional power markets, rather than the simple sum of operational reserve demand in each sub market. In addition, the correlation between electricity tension caused by high demand or low supply is usually very weak from one country to another. Therefore, from the macro level, the power market in a larger region has higher stability and anti risk ability

the ul859:42 power market in a larger region can offset the imbalance between supply and demand in the single market, so the contradiction between supply and demand that needs to be handled in the whole region is lower. From the perspective of investment, this cross-border complementarity of large regions reduces the demand for overall capacity margin, thereby reducing the demand for investment costs

for wind and solar power generation systems, weather is one of the core influencing factors of system fluctuations. If scheduling is carried out in a large geographical area, the volatility of wind and solar power generation systems will be reduced. As the fluctuation of load and resources is reduced, the accuracy of prediction will be improved. At the same time, the diversity of resources can improve the flexibility of the system and reduce the cost of renewable energy

it should be noted that the process of power market integration is not achieved overnight. Since the late 1990s, the European Union has been committed to strengthening the coordination between the power markets of various countries, laying a solid foundation for the creation of a unified EU power market. However, despite the efforts of nearly two decades, the EU electricity market is still developing. Although a certain degree of cross-border power trading system has been established among the neighboring countries of the EU, the power market across the EU has not yet been established

at present, the challenges faced by the EU include: the inconsistent regulatory framework of various countries, the varying degree of development of the electricity market, and the lack of regional or European regulators and system operators. Europe but 5 Argentina has not done so. There are still obvious differences among the countries of the alliance in terms of competitive wholesale and retail markets, market design and functions, the degree of separation and non discrimination of the transmission and distribution system, the participation of the government in the power industry, as well as the independence and function setting of supervision

recently, the European Commission proposed in the legislative proposal of "all Europeans share clean energy" that the integration level of power market and system operation will be further improved in the future. In the proposed "power regulation", one of the specific measures is to propose the establishment of regional operation centers (rocs), which will be a solid step towards regional integration. In order to fully realize the benefits of EU power system integration, rocs should be responsible for the real-time operation of the European regional transmission network, which can optimize the transmission system, improve market efficiency and transform to a low-carbon power system at the lowest cost

based on the European Union's 20-year integrated construction of the power market, we suggest that China should consider some standardization issues in the pilot design at the beginning of the pilot of the power spot market, such as unifying market rules, unifying regulatory framework, and establishing an open market. This is conducive to connecting the provincial markets more effectively in the future, and preparing for a smoother transition to the integrated regional spot market, so that China can obtain the benefits of regional market integration earlier, so that the guide sleeve on the swing rod drives the sample to make a ± 90 ° zigzag
