[0002] In the prior art, in order to facilitate the daily life and work needs of users, deep-gas engines are used to heat and cool the water supply system, and are used as backup power sources; deep-gas engines often use two energy supply methods, one is to directly connect to the natural gas pipeline network, and the other is to connect to the municipal power pipeline network, thereby realizing energy storage of deep-gas engines through natural gas and municipal electricity.

[0003] However, citizens' daily lives and work are inseparable from the energy supply of natural gas pipelines and municipal power pipelines, which means that the natural gas pipelines and municipal power pipelines not only need to meet the daily energy supply needs of deep-burning turbines, but also meet other life and work needs of citizens (especially when the power load is at peak and peak periods), resulting in heavy load pressure on the natural gas pipelines and municipal power pipelines.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0033] The present application provides an energy system, such as Figure 1 As shown, the energy system includes a deep combustion engine 100, a battery device 500 and a solar photovoltaic device 400; the deep combustion engine 100 is connected to a natural gas pipeline network 200 and a city power pipeline network 300, respectively, so as to store energy through the natural gas pipeline network 200 and the city power pipeline network 300; the battery device 500 is connected to the deep combustion engine 100, the solar photovoltaic device 400 and the city power pipeline network 300, respectively, so that the battery device 500 can store energy through the solar photovoltaic device 400 and the city power pipeline network 300, and supply power to the deep combustion engine 100.

[0034] After the battery device 500 described in the present application stores energy through the municipal power network 300 and / or the solar photovoltaic device 400, it can supply power to the deep combustion engine 100, so that the deep combustion engine 100 can not only store energy through the natural gas network 200 and the municipal power network 300, but also store energy through the battery device 500 when the load pressure of the natural gas network 200 and the municipal power network 300 is large, thereby effectively alleviating the load pressure of the natural gas network 200 and the municipal power network 300.

[0035] Furthermore, since the battery device 500 can store energy through the solar photovoltaic device 400 in addition to the municipal power network 300, an efficient and low-carbon energy acquisition method is achieved, and the complementarity of gas (natural gas), electricity (municipal electricity), and light (solar energy) is achieved, which further reduces the energy consumption of the energy system and saves resources.

[0036] It should be noted that if Figure 1 As shown, the deep combustion engine 100 and the solar photovoltaic device 400 can be connected to the water supply system to supply cold and hot water; the deep combustion engine 100 and the solar photovoltaic device 400 can also be used as backup power sources to provide backup power guarantee for the user's normal life and work when a power outage occurs due to a power failure.

[0037] In daily work and life, according to the power load, the power load can be divided into power valley section, power flat section, power peak section and power spike section. Figure 2 As shown, within 24 hours a day: 0:00-8:00 and 11:00-13:00 are all power valleys, 13:00-15:00 and 23:00-24:00 are all power flats, 8:00-9:00 and 17:00-23:00 are all power peaks, and 9:00-11:00 and 15:00-17:00 are all power spikes. It can be understood that the power load gradually increases with the order of power valley, power flat, power peak and power spike.

[0038] In one embodiment of the present application, the energy system also includes a first control valve; the first control valve is arranged between the deep combustion engine 100 and the natural gas pipeline network 200, and is used to control the on and off of the natural gas pipeline network 200 supplying energy to the deep combustion engine 100, so that the staff can cut off the connection line between the natural gas pipeline network 200 and the deep combustion engine 100 according to actual conditions when the deep combustion engine 100 is powered by other means and does not need the natural gas pipeline network 200 to supply energy; or connect the connection line between the natural gas pipeline network 200 and the deep combustion engine 100 when the natural gas pipeline network 200 needs to be used for energy supply.

[0039] In one implementation of this embodiment, Figure 2 As shown, when the power load is in the peak power section and / or the peak power section, the first control valve is in an open state (i.e., the natural gas pipeline network is used to drive the deep combustion engine operation strategy), and the natural gas pipeline network 200 supplies energy to the deep combustion engine 100 to alleviate the load pressure of the municipal power pipeline network 300.

[0040] In one embodiment of the present application, the energy system further includes a second control valve, which is arranged between the deep combustion engine 100 and the mains network 300, and is used to control the on and off of the mains network 300 supplying energy to the deep combustion engine 100, so that the staff can cut off the connection line between the mains network 300 and the deep combustion engine 100 according to actual conditions when the deep combustion engine 100 is powered by other means and does not need the mains network 300 to supply energy; or connect the connection line between the natural gas network 200 and the deep combustion engine 100 when the mains network 300 is needed to supply energy.

[0041] In one implementation of this embodiment, when the power load is in the power valley section, the power load is in the minimum state, and the second control valve is in the open state (i.e., the city power network drives the deep combustion engine operation strategy), so as to supply energy to the deep combustion engine 100 through the city power network 300 in the most economical form. When the power load is in the power peak section and / or the power peak section, due to the high load pressure of the city power network 300, the second control valve can be closed, and the first control valve can be opened, so as to supply energy to the deep combustion engine 100 through the natural gas network 200.

[0042] In one embodiment of the present application, the energy system also includes a third control valve, which is arranged between the deep combustion engine 100 and the battery device 500, and is used to control the on and off of the battery device 500 supplying energy to the deep combustion engine 100, so that the staff can cut off the connection line between the battery device 500 and the deep combustion engine 100 according to actual conditions when the deep combustion engine 100 is powered by other means and does not need the battery device 500 to supply energy; or connect the connection line between the battery device 500 and the deep combustion engine 100 when the battery device 500 needs to be used for energy supply.

[0043] In one implementation of the present embodiment, when the power load is in a flat power section, the third control valve is in an open state (i.e., the deep combustion engine operation strategy is driven by a battery device), so that the deep combustion engine 100 is powered by the battery device 500.

[0044] In one embodiment of the present application, the energy system further includes a fourth control valve, which is disposed between the battery device 500 and the mains power network 300 and is used to control the on / off of the mains power network 300 supplying energy to the battery device 500.

[0045] In one implementation of the present embodiment, when the power load is in a power valley, the power load is in a lowest state, and the fourth control valve is in an open state, that is, the fourth control valve is opened, so that when electricity is sufficient, the municipal power network 300 supplies energy to the battery device 500, thereby preventing the battery device 500 from competing for electricity with other devices.

[0046] In one embodiment of the present application, the energy system further includes a fifth control valve, which is disposed between the battery device 500 and the solar photovoltaic device 400 and is used to control the on and off of the energy supply from the solar photovoltaic device 400 to the battery device 500.

[0047] In one implementation of this embodiment, the fifth control valve is in a normally closed state (i.e., the solar photovoltaic device is used for its own use or supplies energy to the battery device) to ensure that the solar photovoltaic device 400 can continuously supply energy to the battery device 500. When the solar photovoltaic device 400 and / or the battery device 500 have problems and need maintenance or replacement, the fifth control valve can be disconnected.

[0048] In one embodiment of the present application, the battery device 500 includes at least two energy storage batteries; the energy storage batteries are connected to the deep combustion engine 100 and the solar photovoltaic device 400 respectively.
