Embodiment Construction

[0031] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Based on the current trading mode based on medium- and long-term electricity contracts, the present invention designs a trading mechanism that couples power generators' contracts with the frequency regulation market. When the market is sorted out, the units with high performance are given a certain competitive priority and their capacity quotations are compared with The performance quotation is revised; when the frequency regulation market is settled, the incentive amount is set on the basic capacity quotation, and the differential settlement of the frequency regulation auxiliary service for the unit with excellent performance is considered.

[0033] The coupling flow chart of the decomposition of the medium and long-term electricity contract and the clearing of the frequency modulation reserve market is as follows: figure 1 shown. Based on ...

Abstract

The invention discloses a frequency modulation reserve market realization method considering medium and long-term electricity contract decomposition and belongs to the technical field of power system planning. According to the method, energy electricity generation cost, a frequency modulation market prospective earning, a contract completion rate and other factors are considered, an electricity contract is decomposed with the maximum self-interest being a goal, an electricity generation initial curve obtained after contract decomposition is corrected according to a security requirement and contract completion constraint, a transaction priority and a settlement reward amount of a performance superior unit are set through a frequency modulation reserve market ''two-part system'' quotation mode, an electricity generator gives a quotation based on opportunity cost when declaring a capacity price, a market clearing price can reflect the frequency modulation supply and demand situation in a system, the unit is promoted to actively provide a frequency modulation assistance service on the premise of guaranteeing secure operation of the system, and the performance of the unit is improved.

Description

technical field [0001] The invention discloses a method for realizing a frequency modulation reserve market considering the decomposition of a medium- and long-term electricity contract, and belongs to the technical field of power system planning. Background technique [0002] Before the start of the new round of electric power system reform, frequency regulation auxiliary services were carried out in accordance with the "Administrative Measures for the Safety Evaluation of Power Generation Units Connected to the Grid" and the "Interim Measures for the Management of Auxiliary Services for Grid-connected Power Plants" promulgated by the former State Electricity Regulatory Commission. Since the frequency modulation reserve is generally reserved by the dispatching department, the unit output and frequency modulation capacity cannot reflect the system demand, and the specific standards and measurement methods for AGC service compensation in policy documents are relatively rough, ...
