Embodiment 1

[0014] like figure 1 It shows that in an embodiment of the low -carbon operation scheduling method for the energy system for the wind power platform for wind power, it includes steps:

[0015] The islands sea oil and gas field power grid that is to be evaluated to be evaluated as the target power grid system is regarded as the target power grid system. Through steps S100-S600 to evaluate the wind power bearing capacity of the target power grid system, the gas compressor has been turned on during the operation of the Island Oil and Gas Field Power Grid. Run, in this embodiment, the gas compressor refers to the gas compressor that has been opened in the target grid system.

[0016] When scheduling the power compressor power of the target power grid system, you need to reduce the total power of the gas generator as much as possible without violation of the operating constraints of the gas-gas interconnection system to achieve the purpose of low-carbon operation. , Build a linear plann...

example 2

[0038] The specific settings and verification results of sample 1 and example 2 are following.

example 1

image 3 Among the middle, the island micro -grid system contains four 4.5MW gas generators (G1 ~ G4). Fuel gas can be a mixture of natural gas, anger or the two. The total load of the system is 5.82mW, and the powerless power demand is about 3.5mvar, which does not include two gas compressors. Because the gas compressor is the coupling element of the microcontroller and the gas network, the power demand changes with the vapor fluctuations caused by the output of the offshore wind power. In order to make no contribution to the system, a static no exercise (SVG) was installed on the Platform 4. The fuel gas of the gas generator on the platform 1 and 2 takes the nodes 1 and 7 of the gas network.

[0040] The gas network system includes two gas compressors (C1 ~ C2) and two gas sources (S1 ~ S2). The gas compressor is connected to the parent line 2 and 3 of the micro grid. S1 is a source of gas gas, which mainly meets the needs of natural gas factories; S2 is accompanied by gas source...

Abstract

The invention discloses a wind power absorption-oriented low-carbon operation scheduling method for an offshore oil and gas platform energy system, and the method comprises the steps: constructing a target linear programming model for the uncertainty and volatility of wind power, and enabling the target function result of the model to be the minimum gas generator power integration of a power grid system, the constraints of the model comprise a gas power generation and wind power cooperative climbing flexibility constraint, a gas power generation capacity and wind power capacity cooperative flexibility constraint, a gas generator set operation characteristic constraint, a gas compressor operation characteristic constraint and a wind driven generator grid-connected operation characteristic constraint. The dispatching method provided by the invention can effectively cope with the wind power uncertainty and volatility, dispatch the power of the gas generator in the system in the operation process 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 involves the field of new energy technology, and specially involves a low -carbon operation scheduling method for the energy system for the air -gas -gas platform for wind power. Background technique [0002] The power consumption of the maritime oil and gas platform is usually provided by the platform gas generator. The operation and maintenance cost of these equipment is high, and a large amount of carbon dioxide and nitrogen oxide will be emitted, which is very unfavorable to the completion of the carbon and emission reduction targets of the sea oil and gas industry. At present, the wind power at sea is developing rapidly. The operator integrates the deep -sea oil and gas platform with the offshore wind power and runs parallel with the gas -emitted electrical appliances to form an island marine 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 help ...
