Self-adaptive wind-solar complementary heating system

Abstract

The invention relates to a self-adaptive wind-solar complementary heating system and belongs to the field of green energy resource utilization. The self-adaptive wind-solar complementary heating system comprises a wind driven generator, a photovoltaic power generation module, a controller, a boosting unit, a storage battery and loads. The input end of the wind driven generator and the input end of the photovoltaic power generation module are connected with the controller. The output end of the controller is connected with the boosting unit. The boosting unit is connected with the storage battery. The boosting unit traces the maximum power point of output power of the wind driven generator and the photovoltaic power generation module. The storage battery is connected with at least one load. According to the self-adaptive wind-solar complementary heating system, the boosting unit is adopted and can achieve two kinds of power input with different natures, the circuit structure of a traditional multi-input converter is simplified, voltage gain is increased, voltage stress of a switching device is lowered, the generating efficiency is guaranteed, influences on the stability of the system and the effective energy utilization rate at low output power are avoided, and the problems that carbon emission is large, consumption is high and energy is not saved by the adoption of traditional energy resources through a heating method in the prior art are solved.

Description

technical field [0001] The invention relates to the field of green energy utilization, in particular to an adaptive wind-solar complementary heating system. Background technique [0002] At present, there are mainly the following types of heating methods at home and abroad from the division of heating equipment and facilities: one is central heating. This is a relatively traditional heating method, which is mainly divided into municipal heat pipe network and boiler centralized heating in the community. The second is the decentralized heating method: that is, each household independently forms a heating system. The third is the inverter air conditioner, heating in winter and cooling in summer. The fourth is the water source central air-conditioning system, also known as the ground source heat pump, which uses groundwater resources or various water sources at 120-350 degrees 20-30 meters underground to provide 50C-70C cold water for cooling the room in summer; The hot water...

AI Technical Summary

Problems solved by technology

[0003] There are the following problems in the above-mentioned several heating methods: 1. because there are no valves and heat meters for household metering in many residential buildings, the residents cannot adjust the required heat according to their own needs.

②Decentralized heating and inverter air conditioners can flexibly adjust the heating time and temperature according to their own needs, but their cost is very expensive, and air pollution is also an important problem that must be faced

③Water source central air conditioning, also known as ground source heat pump, is an energy-saving and environmentally friendly heating method, but it is severely restricted by groundwater

In short, the above-mentioned heating methods all have the disadvantages of using traditional energy sources such as high carbon emissions, large consumption, and lack of energy conservation, which do not meet the national policy requirements of low-carbon environmental protection, energy conservation and emission reduction.
