Description
Technical field
The present invention relates to power system, more particularly to a kind of two-way peak regulation system of new energy enriching area pneumoelectric.
Background technology
It is well known that China's energy supply and energy demand are in contrary distribution, " Xi Fudong is poor, Bei Duonan in resource
It is few ", it is then on the contrary in demand.It is noted that the fossil energies such as coal, oil are not only in this way, new energy such as wind
Energy, solar energy are also such：More than 80% wind energy resources is distributed in " three Norths " area, and solar energy resources is also that " plateau is more than
Plain, western part are more than east ", and more than 75% energy demand concentrates on east, middle part.
On the one hand " three Norths " regional economic development relatively lags behind, electricity needs is insufficient, electricity market is narrow and small, on the other hand but
It is that fossil energy and new energy are all more plentiful, this just necessarily causes the contradiction that new energy dissolves.
And the explosive growth of " three Norths " regional new energy in recent years has intensified this contradiction.In terms of wind-powered electricity generation, to 2010
In the end of the year, 4182.7 ten thousand kilowatts of China's grid connected wind power, more than the U.S., occupy the whole world first.By the third season in 2015, China's wind-powered electricity generation
Install 108,850,000 kilowatts, turned within short 5 years more.2014, national grid managed region and increases installed capacity of wind-driven power newly
2319.6 ten thousand kilowatts, increase by a year-on-year basis unexpectedly up to 44.2%.Since " 12 ", new energy development is swift and violent.In terms of photovoltaic generation, 2010
The end of the year in year, China's photovoltaic are installed 89.3 ten thousand kilowatts, and by by the end of September, 2015, this numeral has changed into 37,950,000 kilowatts, 5 years
Turned over six kinds it is more.
In terms of natural gas, have the whole world in view, it is trend of the times to improve generating with natural gas consumption ratio.According to Exxon Mobil
《The year two thousand thirty energy outlook is reported》, to the year two thousand thirty, the ratio that natural gas accounts for global Energy Consumption will rise to 25% or so from 20%,
Turn into the second-biggest-in-the-world energy more than coal, reason is that power field sharply increases to Natural Gas Demand.
In terms of the situation of developed country, natural gas turns into the U.S., Japan, the important sources of European electrical power.Have benefited from " page
Rock revolution ", 2000 to 2012, the natural generated energy in the U.S. increased by 96%.The 70% of Japanese natural gas consumption carrys out self power generation neck
Domain, and in view of Fukushima nuclear leakage accident, which causes Japan to restart nuclear power, faces many difficulties, the ratio of following Japanese natural gas power
Example will only increase.Even in the Europe by financial crisis serious blow, natural gas power accounting in its electric structure
Than still 20% to 30%.
In the big China of energy-consuming state of the first in the world, natural gas power also remain faster growth rate.China Power
The data of BVMW are shown, by the end of the year in 2013, China's natural gas capacity of installed generator was 45,000,000 kilowatts or so, is accounted for
The 3.45% of national total installation of generating capacity；Generated energy accounts for the 2.19% of gross generation, has surmounted nuclear power up to 114,300,000,000 kilowatt hours, into
For the fourth-largest power source in China.
The target proposed according to national working energy meeting in 2016, newly-increased wind-powered electricity generation installation 20,000,000 was realized in 2016
Kilowatt and newly-increased 15,000,000 kilowatts of the installation of photovoltaic.At the same time, abandoning wind, to abandon light rate raised once again, is primarily due to power industry entirety
Supply exceed demand.Analyzing Total Electricity Consumption only increases by 0.5% within 2015.National generating equipment averagely only has 3969 using hour within 2015
Hour, it has been minimum since 1978, apparently 2016 annual electricity loads may be still lasting weak and weary at present, if completing national energy
The newly-increased installation target of annual regenerative resource that office fixs before this, abandoning within 2016 the problem of wind abandons light may be more serious, renewable
Energy industry profit will be by more baptism.
The content of the invention
The purpose of the present invention, just it is to provide for a kind of two-way peak regulation system of new energy enriching area pneumoelectric.
To achieve these goals, present invention employs following technical scheme：A kind of new energy enriching area pneumoelectric is two-way
Peak regulation system, including new energy power station, power network, hydrogen production plant by water electrolysis, hydrogen fuel cell process units, natural gas transmission pipe
Road, gas power generator and earth source heat pump；New energy power station connects power network, hydrogen production plant by water electrolysis and earth source heat pump respectively, to
Power network, hydrogen production plant by water electrolysis and earth source heat pump power transmission；Hydrogen production plant by water electrolysis connect respectively hydrogen fuel cell process units and
Natural gas pipeline, hydrogen is conveyed to hydrogen fuel cell process units, or natural gas line is sent into after hydrogen is made into methane；
Gas power generator is connected with natural gas pipeline, power network respectively, receives the fuel gas generation from natural gas pipeline, and
By power Transmission to power network.
The new energy power station includes photovoltaic plant or/and wind power station.
Three northern areas of China one side economic development at present relatively lags behind, electricity needs is insufficient, electricity market is narrow and small, on the other hand
Fossil energy and new energy are all more plentiful, the problem of nowhere consumption this creates the terminal generation of electricity by new energy, it has to new energy
Source generates electricity and limited, that is, " abandon wind and abandon light ".The present invention is as a result of the two-way peak regulation system of new energy enriching area pneumoelectric
System and method, so that it may prepare hydrogen using unnecessary electric energy caused by new energy, hydrogen injects natural gas tube after methane can be made
Road, serve the effect of energy storage.Unnecessary electric energy is also available for earth source heat pump to use.Meanwhile hydrogen may further be used to make hydrogen fuel electricity
Pond, used for manufacture new energy car.And when power network peak of power consumption is come then, remaining electricity gas system can be stopped immediately.Together
When, natural gas driving gas electricity generator can be utilized to generate electricity, supplementary power is carried out to power network, so passes through the anti-of natural gas power
To regulation, solve the problems, such as generation of electricity by new energy randomness, serve the effect of the two-way depth peak regulation of pneumoelectric.System work when institute
Caused heat can be for neighbouring industrial area.Relatively current new energy enriching area abandons wind and abandons light, directly by the feelings of the wasting of resources
For condition, the system is still worth what is utilized.The purpose of construction of the system be construction one it is reliable, stably, friendly, adjustable intelligence
Intelligent energy source use case, substitutes conventional fired power generating unit.
