Embodiment 1

[0035] The low-carbon operation scheduling method for the offshore oil and gas platform energy system for wind power consumption provided by the present invention can be applied in the terminal, and the terminal can use the low-carbon operation and scheduling method for the offshore oil and gas platform energy system for wind power consumption provided by the present invention. During the operation of the energy system of the offshore oil and gas platform, the power of the gas generators in the power grid is dispatched to reduce the carbon emission during the operation of the energy system of the offshore oil and gas platform.

[0036] like figure 1 As shown, an embodiment of the low-carbon operation scheduling method for the offshore oil and gas platform energy system for wind power consumption includes the steps of:

[0140] The specific settings and verification results of Example 1 and Example 2 are described below.

example 1

[0142] image 3 Among them, the island microgrid system includes four 4.5MW gas generators (G1~G4), and the fuel gas can be natural gas, associated gas or a mixture of the two. The total system load is 5.82MW, and the reactive power requirement is about 3.5MVar, excluding two gas compressors. Because the gas compressor is the coupling element of the microgrid and the gas grid, the power demand varies with airflow fluctuations caused by changes in the output of offshore wind power. For reactive power compensation of the system, a static var generator (SVG) is installed on platform 4. The fuel gas for the gas generators on platforms 1 and 2 is taken from nodes 1 and 7 of the gas grid.

[0143] The gas network system includes two gas compressors (C1~C2) and two gas sources (S1~S2). The gas compressors are connected to busbars 2 and 3 of the microgrid, respectively. S1 is the natural gas source, which mainly meets the needs of the natural gas plant; S2 is the associated gas so...

Abstract

The invention discloses a low-carbon operation scheduling method for an offshore oil and gas platform energy system for wind power consumption. The invention builds a target linear programming model for the uncertainty and volatility of wind power. Generator power synthesis, the constraints of the model include the flexibility constraints of gas power generation and wind power synergy, the flexibility constraints of gas power generation capacity and wind power capacity synergy, the constraints of operating characteristics of gas generator sets, the constraints of operating characteristics of gas compressors, and the combination of wind turbines. Network operating characteristic constraints. The dispatching method provided by the invention can effectively cope with the uncertainty and volatility of wind power, dispatch the power of gas generators in the system during the operation of the offshore oil and gas field power grid system, and reduce the carbon emission of the offshore oil and gas field energy system.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a low-carbon operation scheduling method for an offshore oil and gas platform energy system for wind power consumption. Background technique [0002] The power consumption of offshore oil and gas platforms is usually provided by platform gas-fired generators, which are expensive to operate and maintain, and emit a large amount of carbon dioxide and nitrogen oxides, which is very detrimental to the completion of the carbon emission reduction goals of the offshore oil and gas industry. At present, offshore wind power is developing rapidly. Operators integrate deep-sea oil and gas platforms with offshore wind power generation and operate in parallel with gas generators to form an islanded offshore oil and gas field power system. On the one hand, it can save fuel costs and improve production efficiency. On the other hand, it can also help Manage carbon emission reduction in offsho...
