Southern regional electric power market started the trial operation, the speed of the construction of the national unified electric power market
Southern regional electric power market covered Guangdong, Guangxi, Yunnan, Guizhou, Hainan and other five southern provinces, starting the trial operation marks the speed of the national unified electric power market construction, is a milestone in our electric power system reform. It is understood that on the day of the trial operation, more than 157 power plants and users reached the first cross-provincial spot trading in the Southern region through the Southern regional power market trading platform, and the market trading power reached 2.7 billion KWH throughout the day.
The southern regional electricity market includes medium - and long-term, spot and auxiliary service transactions of electricity. After the trial operation, the medium - and long-term trading cycle will fully cover the year, month and week. Spot trading will realize the power spot in the five provinces of the South of the inter-regional and inter-provincial trading; The variety of auxiliary service market and compensation mechanism will be further improved. It is worth mentioning that the spot market will realize the "joint clearing and two-level cooperative operation" of the inter-provincial and intra-provincial spot market, forming the inter-provincial and intra-provincial TOU electricity price and trading curve. The five provinces and regions will operate according to the same trading rules and technical standards. The power generation enterprises and users have more options, and the electricity price can rise or fall according to the actual supply and demand. Barriers to inter-provincial (regional) electricity trading will be broken down, and it will be easier for market players to sell and purchase electricity among themselves.
Intelligent decision-making technology helps optimize the spot clearing of power and promotes the localization of bottom solver.
As an important part of the power market, the spot market clearing of power affects the output of generators, the pricing of power and the operation efficiency of the power grid. During the construction of the southern regional power market, Electricity spot market clearing optimization is a very key and "difficult" link.
Sanshu Technology designed a customized optimization modeling solution for the southern regional power spot market, and created a set of stable, efficient, optimal and interpretable intelligent clearing optimization system. The scheme comprehensively considers the complex constraint features of AC-DC iteration and cascade hydropower, and designs the differentiation algorithm of clearing calculation. The original clearing model of power spot market is deeply customized, which significantly improves the calculation efficiency of spot market clearing, realizes the optimization of unit output distribution, promotes the balance between supply and demand of power spot trading, and effectively reduces the average power generation cost. Improved overall operational efficiency and benefits. At the same time, based on the self-developed optimization solver COPT, Sanshu Technology is also working with China Southern Power Grid to promote the replacement of the bottom solver of spot market clearing system with domestic production, in order to further improve the solution performance and reliability of the whole clearing system, which will also open the first application of home-made customized solver in the domestic power market. As a real domestic self-developed commercial optimization solver, COPT not only reaches the world's leading level in multiple solution performance, but also supports flexible customization and upgrading according to different business scenarios and needs, providing an autonomous controllable, safe and reliable alternative to the solver localization in the energy and power industry.
< /p>With the acceleration of digital transformation, not only the electric power industry, but also the petroleum and petrochemical industries, new energy industries and other energy fields will become a strong application scenario of intelligent decision-making technology. The further development of domestic solver will help the upstream and downstream enterprises of the energy industry chain to comprehensively improve the quality and efficiency. In the future, Sansu Technology will take self-developed solver COPT as the core technology engine, continue to build diversified intelligent decision solutions, accelerate the localization and intelligent process of energy infrastructure construction, and contribute more strength to the digital upgrading of energy industry.
