What does spot trading of electricity mean?
Spot trading of electricity refers to trading in the spot market of electricity. The spot market of electric power mainly includes auxiliary service trading markets such as daily, daily, real-time electric energy and standby, and the spot market, medium and long-term direct trading market and futures electric street original product market constitute the modern electric power market system. As a supplementary part of the market-oriented power balance mechanism, domestic spot trading plays a role in discovering prices, improving trading varieties and forming full competition. Spot trading refers to cash delivery and physical delivery.

At present, the spot market is the main trading platform. Determine the combined power generation of the next unit day in advance, adjust the deviation between the required power generation curve and the medium-and long-term contract, basically realize the power balance of the next day and meet the power grid security constraints.

Intra-day market refers to providing a trading platform for market participants, and fine-tuning the power generation and consumption plans after the market closes a few days ago to cope with various forecast deviations and unplanned situations. Real-time market refers to the organization and implementation hours ago, approaching the real-time operation of the system, truly reflecting the scarcity and congestion of ultra-short-term resources of the system, and realizing the real-time power balance and safe operation of the power grid.

First, there are three differences between the spot trading market and the ordinary market.

1. Electric energy is transmitted at the speed of light and cannot be stored on a large scale. Power generation, transmission, distribution and electricity consumption are completed at the same time, so it is necessary to keep the balance between supply and demand at all times in spot trading of electricity.

2. The transmission cannot exceed the maximum transmission capacity of the power grid, otherwise it will lead to equipment damage, power grid instability or even collapse, because

This kind of on-site power transmission must always meet the power grid security constraints.

3. Once the electric energy is transmitted on the Internet, its quantity and path are determined by the physical laws, not by the contract, and the total amount matching cannot be "one-to-one".

Second, because the production, circulation and consumption of electricity commodities are almost instantaneous and cannot be stored in large quantities, the supply and demand of electricity must be kept in real time balance. In order to ensure the safety of power supply, it is necessary for the dispatching organization to control it accurately. Therefore, in electricity market transactions, according to the length of time for buyers to place orders in advance, they can be divided into medium and long-term markets and spot markets.
