A modular energy management method for wind-solar-storage storage on a floating offshore wind-measuring mobile platform

Abstract

The invention relates to a modular energy management method for a wind-solar storage direct-current power system of a floating type offshore wind measurement mobile platform. The platform consists offour groups of same wind-solar storage power generation devices and platform loads; and the direct-current power system is of an annular bus structure. Each wind-solar storage power generation devicecomprises a wind-solar power generation module and an energy storage module which are connected to a secondary bus through a solid-state switch; the platform loads are divided into multi-stage modulesaccording to the importance of the loads, wherein the one-stage load module comprises most important loads of system operation of radar wind measurement device and system monitoring and the like; each wind-solar power generation module has two power generation modes including a constant-power working mode and a maximum power point tracking (MPPT) mode; and electric energy stored in real time by each energy storage module is measured by state of charge (SOC) values. The safe and stable operation of the system is realized, the power is balanced, and the bus voltage is stable; and therefore, theoffshore wind-solar resource optimization utilization, the charge and discharge management of the energy storage module, and the high-reliability power supply of the platform loads are realized.

Description

technical field [0001] The invention relates to the field of ships and marine engineering and the field of new energy applications, in particular to a modular energy management method for wind-solar-storage storage of a floating offshore wind-measuring mobile platform. Background technique [0002] Renewable energy is of great significance to the sustainable development of mankind, and the fastest growing renewable energy in the world is none other than wind energy. For the construction needs of offshore wind farms, through real-time measurement, collection and transmission of wind, waves, and currents in the target sea area, the wind energy evaluation of the enrichment and distribution of wind energy resources in the initial stage of offshore wind farm construction is realized, and the optimal layout of wind farms is realized.

Problems solved by technology

[0003] At present, wind tower-type wind-measuring platforms are generally used in the initial stage of offshore wind farm construction. As offshore wind power develops from shallow seas to deep seas, there are technical difficulties and time costs in the construction of wind-measuring towers, and later operation and maintenance are more difficult.

Its construction cost and operation and maintenance cost are high, and it is vulnerable to typhoon
