Embodiment 1

[0063] Embodiment 1 provides a method for optimizing the contract coverage ratio of new energy generating units, which aims to convert the interrelated three-layer model into a single-layer model through KKT conditions, so as to calculate the optimal solution for the contract coverage ratio of new energy generating units.

[0064] Combining current policies and new energy development levels, this embodiment proposes a multi-market and multi-subject transaction framework involved in the transition mechanism, and establishes a three-tier optimization decision-making model that considers multiple market subjects, thereby realizing the scientific design of the market transition mechanism. Enhance the rationality and effectiveness of policy formulation. The above-mentioned three-layer optimization decision-making model that considers multiple market entities is established according to the transaction framework. The trading framework gradually guides new energy units to participate...

Abstract

The invention discloses a new energy unit contract coverage rate optimization method which is used for solving the problem that an effective connection and transition mechanism is urgently needed when an existing new energy unit participates in an electric power spot market, and the method comprises the following steps: according to renewable energy unit prediction output data, electric power spot market clearing data and green certificate market clearing data, calculating the contract coverage rate of the new energy unit; establishing an upper layer model; establishing a middle-layer model according to the quotation data of the participating units of the electric power spot market and the quotation data of the participating units of the green certificate market; establishing a lower-layer model according to the income data of the new energy unit in the electric power spot market and the green certificate market; and converting the three-layer model through a KKT condition to obtain an optimal result of the contract coverage rate of the new energy unit. The invention further discloses a new energy unit contract coverage rate optimization device, electronic equipment and a computer storage medium. According to the method, the three-layer model is converted into the single-layer model through the KKT condition, and then the optimal solution of the new energy machine combination coverage rate is obtained.

Description

technical field [0001] The present invention relates to the technical field of electricity spot market, in particular to a method, device, equipment and medium for optimizing contract coverage ratio of new energy generating units. Background technique [0002] With the "carbon peak, carbon neutral" goal put forward, China's new energy industry has developed rapidly. The subsequent increase in the subsidy gap of new energy units has also become increasingly prominent. To this end, the energy authorities have continuously lowered the benchmark electricity prices for photovoltaic and wind power subsidies, in an effort to reduce the government's financial subsidy pressure on new energy units. Although this is conducive to alleviating financial pressure, it has brought about a new problem of a sharp decline in the growth rate of new energy installations. [0003] In order to alleviate this contradiction, some mature foreign power markets will use a combination of "financial con...
