Abstract

The invention discloses an offshore energy internet based on a flexible direct-current power grid. The offshore energy internet comprises the flexible direct-current power grid, a new energy power supply system connected to the flexible direct-current power grid, and a power utilization system; the power utilization system comprises a hydrogen production system, a ship shore power utilization system, a petroleum drilling power utilization system and a cool, heat and power multi-energy complementary system, wherein direct current of the hydrogen production system is connected into the flexible direct-current power grid, and an alternating current/direct current converter of the petroleum drilling power utilization system is connected into the flexible direct-current power grid. According to the offshore energy internet based on the flexible direct-current power grid of the invention, 100% consumption of new energy in a harbor district can be realized, the consumption proportion of electric energy to terminal energy is greater than 50%, a scheme capable of being popularized and applied on a large scale is formed, and a feasible path is explored for realizing carbon neutralization in the energy power industry.

Description

technical field [0001] The invention belongs to the field of offshore energy, in particular to an offshore energy internet based on a flexible DC power grid. Background technique [0002] The proposal of the goal of "carbon peaking and carbon neutrality" provides a power engine for my country's economic and social development, and provides a major strategic opportunity for the energy and power industry to seize the commanding heights of the world. However, there is currently no offshore carbon-neutral energy Internet demonstration area in China, and there is a lack of large-scale promotion and application plans for zero-carbon energy Internet. Therefore, it is urgent to explore an implementation path for offshore carbon-neutral energy Internet to support the early realization of carbon neutrality in energy and power systems. Contents of the invention [0003] In view of the above problems, the present invention provides an offshore energy internet based on a flexible direc...
