Embodiment Construction

[0065] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0066] After the electric power spot market starts a few days ago, the market load is divided into two parts, which become the bidding space for adjustable power stations and non-adjustable power stations respectively.

[0067] According to the market-related information released by the power dispatching agency, the cascade hydropower upstream power stations participating in the market declare the price of electric energy in...

Abstract

The invention discloses a basin cascade upstream and downstream power station participation electric power spot market secondary clearing method. Compared with the prior art, the agent mechanism and the water and electricity benefit compensation mechanism are provided; the secondary clearing mode can ensure that the cascade hydropower upstream and downstream power stations have sufficient participation degree in the spot market as power generators, the bid winning amount and the actual distribution amount of the downstream power stations are kept consistent without joint bidding, and market transaction balance is ensured.

Description

technical field [0001] The invention relates to the technical field of water resource utilization, in particular to a method for secondary clearance of cascaded upstream and downstream power stations in a river basin to participate in a power spot market. Background technique [0002] At present, various provinces in my country are actively carrying out the construction of electric power spot markets, and cascade hydropower, as the largest clean energy, will definitely participate in the spot market. Cascade hydropower has the characteristics that the upstream power station has strong regulation ability, while the downstream power station has poor regulation ability. Therefore, the upstream power station can participate in flexible bidding in the market based on its own excellent regulation and storage capacity; however, the downstream power station relies on the power generation capacity of the upstream power station to bid independently more difficult. At the same time, s...
