Description

Technical Field

[0001] The present invention belongs to the field of life configuration in high altitude areas, and specifically relates to a method for configuring a high-quality life system for communities in high altitude areas that integrates electric heating and multi-fuel synergy. Background Art

[0002] Due to the thin air in high altitude areas, the large temperature difference between day and night, and the average temperature of glacier meltwater below 10 degrees all year round, the basic infrastructure such as power supply, heating, oxygen supply and vegetable supply for local residents and border outposts is poor, especially the heating demand is large and autonomous decentralized heating, but just like the Qinghai altitude, there is also a boundary time of the heating season. The heating period in Qinghai Province is usually from October 15th to April 15th of the following year, with a heating period of half a year. At higher altitudes, the heating demand is greater and the heating period accounts for more than 50% of the year. In addition, road transportation is inconvenient in remote villages in high altitude areas, and it is difficult to effectively guarantee important energy and materials for maintaining life such as electricity, heat, oxygen and vegetables.

[0003] Solar energy resources are abundant at high altitudes, but due to the mountainous terrain and different lighting conditions in different regions, photovoltaic power generation sources are complex: they are composed of direct sunlight, reflected light from mountains and snow-capped mountains, and scattered light, which has the uniqueness of local lighting. At the same time, the energy demand for work and life does not match the rising and setting of the sun and seasonal changes. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for configuring a high-quality life system for communities in high-altitude areas that integrates electric heating and multi-fuel synergy. It proposes a configuration method that uses photovoltaic power generation as energy, electricity storage, heating, heat storage, hydrogen production, and compressed air as loads, and uses the equipment in coordination with each other based on physical characteristics and load requirements. Taking seasonal changes into consideration, photovoltaic power generation + chemical energy storage battery energy storage is used to power the load in the non-heating season, and hydrogen is produced and stored at the same time. In the heating season, fuel cells are used to power the load to solve the problem of cross-seasonal electricity demand. In the heating season, photovoltaic power generation solves the heating problem through photovoltaic power generation heating, sensible heat storage, and biomass collaboration.

[0005] The problem of oxygen supply is solved by using nitrogen protection in a compressed air sealed cabin, and the oxygen produced in the hydrogen production process is used to assist biomass or other boilers to generate heat for daily life. The exhaust carbon dioxide hot gas is supplied to the vegetable greenhouse, and the hydrogen storage is used to generate electricity through fuel cells to supplement seasonal energy shortages. The LED vegetable greenhouse supplements the light to increase the duration of vegetable illumination and promote vegetable photosynthesis, thereby solving the problem of comfortable life throughout the year in high-altitude areas. At the same time, the problem of mismatch between demand load and solar energy time, the problem of efficient use of equipment, the problem of energy supply security, and the improvement of energy utilization rate are solved to provide a comfortable life on the plateau. At the same time, considering the local economic development, affordability, practicality, operability, friendliness, and reliability, a configuration method for creating a high-quality life system for communities in high-altitude areas based on the synergy of electricity, heat, oxygen, and hydrogen is proposed.

[0006] The principle of the present invention is: photovoltaic power generation provides a bidirectional energy storage inverter to power the load and chemical energy storage battery, photovoltaic water electrode heat storage boiler for heating / sensible heat storage, and electrolyzer for hydrogen production. Based on the local heating season and non-heating season, the duration of photovoltaic power generation, heat storage, hydrogen production, and hydrogen storage is determined; when supplying power, photovoltaic power generation supplies power to the load, and a bidirectional energy storage inverter is used to provide energy from chemical energy storage batteries or fuel cells, wherein the fuel cell stores hydrogen across seasons through photovoltaic power generation in the non-heating season to realize fuel cell power supply; when supplying heat, photovoltaic power generation is based on the water electrode heating principle, and provides heat for domestic use through photovoltaic water electrode heat storage boiler heating and sensible heat storage.

[0007] Since the electrolyzer hydrogen production and bidirectional energy storage converter have the best power range and the lower limit voltage limit of the start-up, the bidirectional energy storage converter and the photovoltaic water electrode heat storage boiler both have the ability to track the maximum power point MPPT of photovoltaic power generation. When the photovoltaic power generation capacity is constant, the maximum power point characteristics of solar photovoltaic power generation and the 0~100% power linear heating characteristics of the photovoltaic water electrode heat storage boiler are fully utilized. The photovoltaic water electrode heat storage boiler is combined with the bidirectional energy storage converter or the electrolyzer hydrogen production equipment to achieve the optimal distribution of photovoltaic power generation energy during the photovoltaic power generation cycle and the lossless absorption of the maximum power of photovoltaic power generation. That is, the energy storage power supply of the bidirectional energy storage converter, the hydrogen production of the electrolyzer, and the water heating of the photovoltaic water electrode heat storage boiler are realized, and the maximum utilization rate of solar power generation is guaranteed.

[0008] In order to adapt the electrolyzer hydrogen production to the fluctuation of photovoltaic power generation, the electrolyte of the electrolyzer hydrogen production is exchanged with the constant temperature zone of the photovoltaic water electrode heat storage boiler to ensure that the electrolyzer is always in the best constant temperature state.

[0009] Among them, the MPPT tracking principle of photovoltaic power generation is: due to the lower limit voltage limit of the electrolyzer hydrogen production and the bidirectional energy storage converter, and the photovoltaic water electrode heat storage boiler is based on the water resistance heating principle, the water resistance heating power is The linear load power can be adjusted from 0~100% power, and the maximum power output of the photovoltaic module can be responded by adjusting the water resistance heating power. It can also be combined with a bidirectional energy storage inverter or electrolyzer hydrogen production to quickly respond to the maximum power output of the photovoltaic module.

[0010] In order to achieve cross-seasonal power supply, photovoltaic power generation is used in the non-heating season to directly produce and store hydrogen in the electrolyzer. In the heating season, photovoltaic power generation is insufficient, and a two-way energy storage inverter power supply is provided by a fuel cell to supply power to the load. Among them, the electrolyzer hydrogen production process is accompanied by oxygen to help biomass and other boilers to generate heat for domestic use, and the discharge of carbon dioxide helps to heat up the vegetable greenhouse. At the same time, it cooperates with LED supplementary lighting technology to improve plant photosynthesis and promote rapid plant growth.

[0011] When supplying oxygen, a sealed insulated cabin is used to place photovoltaic inverters, storage batteries, fuel cells and other devices inside, and an air compressor is used to compress air into the sealed cabin to ensure 1 atmosphere of pressure, and nitrogen is retained through semi-permeable membrane technology. On the one hand, this ensures that the equipment can be used without derating, positive pressure can prevent dust, equipment dissipates heat through nitrogen and sealed cabin heat exchanger, and nitrogen protection can be used for active fire prevention. On the other hand, oxygen is produced through air separation to meet the national standard for oxygen use by humans and provide oxygen for life.

[0012] Since glacier meltwater is the source of water for local people's lives, low-temperature water brings too many changes to people's lives. By introducing glacier meltwater into the sealed cabin heat exchanger, on the one hand, the temperature of the sealed insulation cabin is exchanged with low-temperature water to ensure the stable operation of the equipment inside the sealed insulation cabin, and on the other hand, the temperature of the glacier meltwater is increased, and the preheated glacier meltwater enters the photovoltaic water electrode heat storage boiler for heating, reducing the heating power of the photovoltaic water electrode heat storage boiler and improving the comfort of local people's lives.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1 As shown, the electricity, heat, oxygen and hydrogen collaboratively create a high-quality life system in high-altitude areas, which is composed of a photovoltaic array 1, a sealed insulation cabin 2, a compressed gas unit 3, an electrolyzer 4, a bidirectional energy storage inverter 5, and a photovoltaic water electrode heat storage boiler 6.

[0034] The sealed insulation cabin 2, electrolyzer 4, bidirectional energy storage inverter 5, photovoltaic water electrode heat storage boiler 6 are relatively concentratedly arranged around the living area, and the photovoltaic array 1 is arranged at a place suitable for photovoltaic power generation around the living area.

[0035] The photovoltaic array 1 is the main energy source for providing electricity and heat to local residents. The photovoltaic power generation output passes through the sealed insulation cabin 2 and is connected to the bidirectional energy storage inverter 5 to provide load electricity and charge the chemical energy storage battery 7; it is directly connected to the electrolyzer 4 to provide energy for hydrogen production by the electrolyzer 4 and hydrogen storage tank 8; it is directly connected to the photovoltaic water electrode heat storage boiler 6 to provide heating and sensible heat storage energy. At the same time, the 0~100% power adjustable feature of the photovoltaic water electrode heat storage boiler 6 is utilized to cooperate with the electrolyzer 4 to produce hydrogen, so as to achieve the optimal power hydrogen production of the electrolyzer 4 and the maximum power tracking utilization of photovoltaic power generation, and efficiently utilize the photovoltaic power generation efficiency.

[0036] In addition to the bidirectional energy storage converter 5, the sealed insulation cabin 2 also includes a fuel cell 10, a sealed cabin heat exchanger 11, and a chemical energy storage battery 7. The main controller 24 is embedded on the wall of the sealed insulation cabin 2, the controlled pressure reducing valve 25 is embedded on the cabin top, and the compressed gas unit 3 is installed outside the cabin; the bidirectional energy storage converter 5, the fuel cell 10, the sealed cabin heat exchanger 11, and the chemical energy storage battery 7 are distributed and installed in the sealed insulation cabin 2 according to the optimal connection relationship, and the sealed cabin heat exchanger 11 is placed on the top of the sealed insulation cabin 2. The main controller 24 is connected to all equipment, sensors, and control valves through communication lines, reads data, and controls in real time according to the control strategy. The pressure in the sealed insulation cabin 2 is guaranteed by the controlled pressure reducing valve 25, and the local oxygen demand for life is provided while the equipment is safely operated.

[0037] Preferably, the compressed gas unit 3 includes an air compressor 12, a nitrogen and oxygen separation module 13 and an oxygen storage cylinder 14. The gas compressed by the air compressor 12 passes through the nitrogen and oxygen separation module 13, and the nitrogen is compressed into the sealed insulation cabin 2, providing nitrogen of a certain pressure in the sealed insulation cabin 2, which is a positive pressure nitrogen protection measure relative to the local atmosphere, and mainly plays the role of fire prevention, dust prevention, heat exchange and avoiding equipment derating; and the nitrogen and oxygen separation module 13 produces oxygen produced by air separation and is compressed into the oxygen storage cylinder 14, which meets the national standard for human oxygen use and provides oxygen demand for life. Among them, the nitrogen in the sealed insulation cabin 2 is used as the exchange medium between the equipment and the sealed cabin heat exchanger 11, and the introduced glacier meltwater 15 is used through the sealed cabin heat exchanger 11 to regulate the temperature in the sealed insulation cabin 2 through heat exchange, thereby ensuring the optimal working temperature inside the sealed insulation cabin 2 while increasing the temperature of the glacier meltwater.

[0038] The bidirectional energy storage inverter 5 receives the power generation energy of the photovoltaic array 1, charges and discharges the chemical energy storage battery on the one hand, and supplies power to the load on the other hand. During periods of weak light or no light, when the power generation of the photovoltaic array 1 cannot meet the charge and discharge of the chemical energy storage battery 7 to supply power to the load, the fuel cell 10 converts the hydrogen stored across seasons into electrical energy, and supplies power to the load through the bidirectional energy storage inverter 5.

[0039] The process of hydrogen production by the electrolyzer 4 and hydrogen storage by the hydrogen storage tank 8 is during the period of abundant power generation of the photovoltaic array 1. The accompanying oxygen production and oxygen storage in the oxygen storage tank 16 are used to solve the problem of cross-seasonal power supply for daily life. The oxygen produced by the electrolyzer 4 and hydrogen storage tank 8 cannot be directly used for human oxygen supply due to industrial oxygen production. Therefore, the oxygen is stored in the oxygen storage tank 16 and discharged to assist the full combustion of the combustion medium of the biomass boiler 17 or other boilers. On the one hand, it provides heat for daily life. On the other hand, it produces carbon dioxide gas and carries heat, such as heating for vegetable greenhouses 18 and cooperates with LED supplementary lighting technology to improve plant photosynthesis and promote rapid plant growth.

[0040] The photovoltaic water electrode heat storage boiler 6 is directly connected to the power generation output of the photovoltaic array 1, and uses the water electrode heating principle to convert electricity into heat through the water electrode heating system 9, and uses the sensible heat storage principle of water to store heat for each day. At the same time, it coordinates with the photovoltaic array 1 output parallel electrolyzer 4, and uses the 0~100% power adjustable feature of the photovoltaic water electrode heat storage boiler 6 to cooperate with the electrolyzer 4 to produce hydrogen, so as to achieve the photovoltaic water electrode heat storage boiler 6 heating and sensible heat storage, and at the same time achieve the optimal power hydrogen production of the electrolyzer 4 and the maximum power tracking and utilization of the photovoltaic array 1, so as to efficiently utilize the photovoltaic power generation efficiency. The irradiation meter 26 is installed next to the photovoltaic array 1 to monitor the light intensity in real time.

[0041] Preferably, the photovoltaic water electrode heat storage boiler 6 is divided into a top constant temperature zone 19 and a heating zone 20, and the heating zone 20 is isolated from the top constant temperature zone 19 by an insulating material 21. The heating zone 20 mainly applies the output power of the photovoltaic array 1 to the water resistor through the water electrode to generate heat to heat the water body. The top constant temperature zone 19 is mixed with a certain amount of relatively warm water output by the sealed cabin heat exchanger 11 to ensure the top constant temperature zone 19 in the photovoltaic water electrode heat storage boiler 6.

[0042] In order to adapt to the rapid response of electrolyzer 4 to the fluctuation of photovoltaic power generation, the electrolyte produced by electrolyzer 4 is exchanged with the constant temperature zone heat exchanger 23 of the photovoltaic water electrode heat storage boiler through the electrolyte heat exchanger 22 to ensure that the electrolyzer 4 is always in the best constant temperature state. The constant temperature zone heat exchanger 23 is installed in the top constant temperature zone 19, and the electrolyte heat exchanger 22 is installed in the electrolyte. The constant temperature zone heat exchanger 23 and the electrolyte heat exchanger 22 exchange heat through the water pipeline.

[0043] As the glacier meltwater 15 is the water source for local people's lives, the glacier meltwater 15 is introduced into the sealed cabin heat exchanger 11. On the one hand, the temperature of the sealed insulation cabin 2 is exchanged by low-temperature water to ensure the stable operation of the internal equipment of the sealed insulation cabin 2. On the other hand, the temperature of the glacier meltwater 15 is increased, and the relatively warm water output by the sealed cabin heat exchanger 11 enters the photovoltaic water electrode heat storage boiler 6 for further heating, thereby reducing the heating power of the photovoltaic water electrode heat storage boiler 6 and improving the living comfort of local people.

[0044] like Figure 2 As shown, a configuration method of a high-quality life system for communities in high-altitude areas integrating electric heating and multi-fuel synergy of the present invention comprises the following steps: Step 1: Determine the functions and load requirements of the high-quality living system in high-altitude communities and obtain basic data, including: Due to the relatively harsh climate in high-altitude areas and the lack of local resources, it is difficult to ensure basic electricity, heat, and oxygen. Therefore, we consider using solar energy and local biomass resources to provide local electricity, heat, oxygen, and vegetable needs for work and life throughout the year in an off-grid state. However, the energy demand for work and life does not match the rising and setting of the sun and seasonal changes. Therefore, we consider the high-efficiency utilization of energy and give full play to the utilization of associated and by-product energy realized by the function of equipment. Through reasonable energy distribution, optimal equipment configuration, cross-seasonal energy storage technology, and optimized control methods, we can achieve local electricity, heat, oxygen, and vegetable needs for work and life in an off-grid state throughout the year.

[0045] The determination of the requirements includes: 1. Considering economy, reliability, operability and functionality, according to the load demand in heating season and non-heating season, with solar photovoltaic power generation as the main energy source, chemical energy storage battery energy storage and hydrogen production and storage technology are combined to realize year-round power supply; 2.
