Coastal reclamation area wind energy-solar energy-fishery-reservoir-agriculture three-dimensional complementary layout system

Abstract

The invention relates to the technical field of coastal reclamation area soil improvement and coastal energy complementation, in particular to a coastal reclamation area wind energy-solar energy-fishery-reservoir-agriculture three-dimensional complementary layout system. The system comprises a wind power generation module, a photovoltaic utilization module, a plain reservoir, a fishery breeding module and an agricultural planting module; the plain reservoir is a plain reservoir at a coastal area; photovoltaic utilization modules are evenly installed on the periphery of the plain reservoir; the photovoltaic utilization modules store converted electric energy in an energy storage device; and wind power generation modules are fixedly installed on the peripheries of the two sides of each photovoltaic utilization module. With the coastal reclamation area wind energy-solar energy-fishery-reservoir-agriculture three-dimensional complementary layout system of the invention adopted, the fishery breeding variety and agricultural planting structure of the coastal reclamation area can be enriched, the coastal deep water freshwater fish breeding technology can be developed, and the planting market of coastal tropical crops, spices, specific drugs and the like can be expanded; and meanwhile, the inherent defects of unstable generated power and electric quantity of single wind power generation or photovoltaic power generation can be overcome, so that the difficulty of accessing the electric quantity of a power grid is reduced.

technical field [0001] The invention relates to the technical field of soil improvement in coastal reclamation areas and complementary coastal energy sources, and in particular to a three-dimensional complementary layout system for scenery, fishery, storage and agriculture in coastal reclamation areas. Background technique [0002] With the development of my country's economy and society and the rapid growth of land demand, coastal tidal flat resources such as Jiangsu, Zhejiang, and Fujian, as potential land resources with the most development value, will become a new growth point for my country's economic development. For example, coastal tidal flats in Jiangsu It silts up at a rate of more than 20,000 mu every year, which is the highest proportion of all the land available for development in Jiangsu. However, due to the serious salinization of reclamation land, low-lying terrain, and lack of fresh water resources, the development level of coastal tidal flat resources is curr...

[0002] With the development of my country's economy and society and the rapid growth of land demand, coastal tidal flat resources such as Jiangsu, Zhejiang, and Fujian, as potential land resources with the most development value, will become a new growth point for my country's economic development. For example, coastal tidal flats in Jiangsu It silts up at a rate of more than 20,000 mu every year, which is the highest proportion of all the land available for development in Jiangsu. However, due to the serious salinization of reclamation land, low-lying terrain, and lack of fresh water resources, the development level of coastal tidal flat resources is currently low. , Utilization direction is single, and the efficiency of comprehensive resource utilization is not high, which has restricted the economic and social development of coastal areas and has become one of the problems that need to be solved urgently

[0003] In recent years, energy complementarity is an important technical means for the comprehensive utilization of coastal resources. The energy complementarity models that have been popularized and applied with good effects include "window" complementarity, "fishing-solar" complementarity, "agricultural-solar" complementarity, "window-solar-fishery" complementarity, "Agriculture, fishery and light" complementarity, etc. These energy complementarity modes mainly realize the complementarity and comprehensive utilization of different energy structures through the rational use of natural resources, so as to improve resource utilization efficiency, but these complementary modes also have some problems in practice: for The widely used "wind-solar" complementary system, due to the characteristics of low energy density, poor stability, strong volatility and randomness of wind power and photovoltaics, has a low energy utilization rate, and is mostly used in the field of coastal navigation marks, ship power supply systems, street lights, etc. In the lighting system or backup power generation system, the application scale is small and the application scope is relatively limited. For the existing "fishery and agriculture" complementary and "fish-agricultural symbiosis" systems, under the premise of ensuring good fish species and reliable water sources, appropriate Increase fishery output and improve soil fertility, but the freshwater resources and arable land resources in China's coastal areas are scarce. How to develop freshwater fish farming in China's coastal areas, how to increase the production of freshwater fish per unit area in a limited water area, and how to improve the non-ferrous land in coastal reclamation areas Cultivated soil is arable soil, which is worthy of in-depth exploration. In summary, although there are many energy complementary models and application examples in China at present, considering the unique soil structure and energy status of coastal reclamation areas, these complementary models are not fully applicable.
