ClicksReport: As of March this year, a new round of power system reform involving the five links of power system generation, transmission, distribution, sales, and use has gone through five years. Under the combined effect of the series of power reform measures, the scale of my country's electricity market-oriented transactions has been expanding year by year. By 2019, the national electricity market has only medium-to-long-term direct transaction electricity to reach 217.74 billion kWh, accounting for 30.1% of the total electricity consumption in the society.
The reform of the electric power system is a profound adjustment of the power industry’s productivity and production relations. It is a systematic project that requires the participation of governments, enterprises, relevant universities, research institutions, and social groups. Therefore, changing the power system reform to a "live method" is to transform the previous one-way chain structure of the power industry into a basic pipe network channel with the power grid as the basic pipeline network. Power generation, power grid, power sales, users and emerging business types can be connected. Directly interactive multi-directional network structure. my country's power grid has benefited from the development of UHV. The large power grids in all regions of the country are connected to each other to form a unified national power grid, which realizes the overall optimization of supply and demand resources in the unified region, fully taps and releases the potential of power generation resources in connected areas, and maximizes social welfare . Over the past five years, my country’s power system reform has been gradually and in-depth. Through grid cost supervision and review, transmission and distribution price verification to "control the middle", through continuous promotion of independent and standardized operation of trading institutions, continuous expansion of the scale of market-oriented power transactions, and acceleration of incremental distribution Electricity business reforms and steadily advancing the construction of the electric spot market to "liberate the two ends", and the innovation of electric power system and mechanism continues to win new breakthroughs. Today, China has become the first country in the world to fully master UHV AC and DC transmission technology and realize commercial operation, occupying the commanding heights of the world's power transmission technology, and realizing the "created in China" and "led by China" in the field of world transmission technology; Major technical problems such as large-scale power grid dispatching and operation, wide-area dynamic monitoring, etc., independently researched and developed a new generation of simulation system with the strongest simulation capability, the highest calculation efficiency, and the most accurate simulation accuracy, and a standard based on the "Power System Safety and Stability Guidelines" China’s power grid has become the only super-large power grid in the world that has not had a blackout in the past 20 years. Since 2007, the State Grid has also increased overseas investment with the Philippines, Brazil, Portugal and other countries to promote grid interconnection and international Energy cooperation.
As a result, the reform of the electric power system is by no means a short-term effort, let alone accomplished overnight. We must minimize the unreasonable intervention of the "visible hand" of the government, make full use of the "invisible hand" of the market, and increase the reform of incremental power distribution business, promote power trading, reforms on the sales side, and increase The reform of mass distribution business and the construction of pilot power spot market to maintain order, so as to provide strong power guarantee for my country’s economic development.
