In the near future, the electric power market reform has been accelerated, and after the comprehensive promotion of the verification of cross-regional and regional power grid transmission and distribution prices, it has begun to move forward to the establishment of the spot market.
On August 28, the national development and reform commission issued the physical file on the conduct of the pilot power spot market construction notice "(hereinafter referred to as" notice "), to determine the start (guangdong), stake, south zhejiang, shanxi, shandong, fujian, sichuan, gansu and other eight regions as the first batch of pilot and request to speed up the organization to promote electricity spot market construction work. Launch the spot market test run by the end of 2018.
According to the time division, the transaction of the above days is referred to as the medium - long term (or long term) transaction, which is called the spot trading of electric power.
With the development of power system reform, the medium - and long - term trading scale has been expanding. "Notice", according to the need to speed up to explore establishing electricity spot trading mechanism, changing the mode of planning and scheduling, found that electricity prices, form power balance of market-oriented mechanism, build long-term trading and spot trading of the combination of electric power market system.
Now abandon wind, discard, abandoned water is serious, especially wind power and photovoltaic, stochastic volatility is big, in the absence of electricity spot market, only under the condition of medium and long-term contract market, these new energy power is hard to enter the market value. With the spot market, because of the real-time market, wind power and photovoltaic can be quoted at marginal cost in the market to reflect their value. At the same time, the value of traditional energy for scenic peak can also be reflected in the spot market.
In principle, the pilot project should be carried out in accordance with the existing power dispatching control zone (considering trans-provincial and cross-regional delivery of electricity), and the areas with conditions can actively explore the merger control area. The electricity spot market construction pilot mature one, start one.
According to international experience, the harmonization of these two rules is very important. It can not affect the safe operation, but also ensure that the market can find the value of the electric goods through spot price signals to guide the behavior of both suppliers and suppliers. If it does not, the spot market becomes empty and does not show real value. But the safe operation of electricity is also crucial.
In accordance with the "notice" requirements, the pilot areas around time-sharing electricity price mechanism, the formation of days in the spot market, on the basis of the optimization goal, set up safety under the restriction of the spot market clearing mechanism and congestion management mechanism.
In addition, the organization market main body to carry out a few days ago, days, real-time electric energy trading, to realize the organic link and the operation of market transactions, and promote the safe operation of power system, the efficient operation of the market, forming time and position characteristic of electric energy commodity prices, as the market main body to provide reflect market supply and demand and production cost price signals.
