Description
Technical field
The present invention relates to electric power storage facility application field, more particularly to a kind of block chain electric power based on distributed electric power storage facility
Transaction peak-frequency regulation system.
Background technology
In recent years, with the raising of living standards of the people and the rapid growth of electric load, network load peak-valley difference is progressively
Increase, at the same time, randomness, fluctuation, the regenerative resource large-scale grid connection of non-scheduling, causes the peak regulation of power network to be asked
Topic is more prominent, also causes a series of difficulty to power scheduling.Power supply and equipment for power transmission and distribution are according to power network in power system
Peak load planning construction, but the peak load of grid duration is shorter, cause for meet peak load demand and planning construction
Power equipment asset utilization ratio it is relatively low.It is power grid construction at this stage to research and solve peak load regulation network problem, improve asset utilization ratio
The important topic faced.
For the power supply architecture of China based on thermoelectricity, most conventional fired power generating unit is capable of the scarce capacity of flexible modulation output
The 50% of rated capacity, when load peak-valley difference is less than the adjusting range of fired power generating unit, it is necessary to which part small-load generators start and stop are adjusted
Peak or banking fire peak regulation, or even need the more units of investment construction and improve the method for operation of fired power generating unit to meet peak regulation demand,
So as to be added significantly to the operating cost of system.According to statistics, the peak-valley difference of China in Recent Years network load is 38%~48%, with
Exemplified by Liaoning electric power grid, Liaoning electric power grid peak load in 2011 is 22362MW, and low ebb load is 12708MW, and peak-valley difference is
43.2%.Peaking problem is the basic problem in operation of power networks.Start and stop are rapid, the flexible peak regulation technique of the method for operation meets power network
The application demand of peak regulation technique.In power system routine peak regulation technique, compared to fired power generating unit, Hydropower Unit start and stop are rapid,
The method of operation is flexible, and peak regulation depth is close to 100%, but the construction of Hydropower Unit is limited by geographical conditions, it is impossible to carries out big
The popularization and application of scale.
Extensive battery energy storage system has superior peaking performance because of its fast response characteristic, can be in the low power consumption phase
Electric energy is stored as load, discharges electric energy as power supply in peak times of power consumption, realizes generate electricity decoupling and Load Regulation between electricity consumption,
Reduction plans peak-valley difference, and its construction is not limited by geographical conditions.With lithium ion battery, vanadium redox battery, sodium
Sulphur battery is the battery energy storage system of representative, can effectively delay or even reduce power supply and power grid construction, improve efficiency of energy utilization
Level is utilized with power network total assets, changes the construction mode of existing power system.
The principal element for influenceing energy storage technology in power domain scale application mainly includes energy-storage system scale, technology water
Flat, security and economy.When the capacity of energy-storage system reaches MW/MWh level scales ability, meets safety under MW/MWh levels
Property, cycle life reach 5000 times and when the above, efficiency for charge-discharge reach 80% and the above, the high cost of energy-storage system turns into limit
Make the key factor of its large-scale application.
The appearance of bit coin in 2009 brings a kind of subversive achievement -- and block chain technology, block chain are a safety
Account book class database, be made up of data block one by one, user can this continuous renewal upgrading platform search number
According to, for financial institution, block chain can accelerate trading processing process, reduce cost, reduce go-between, improve market see clearly
Power, increase business transparency.
Floor layer Technology of the block chain as encryption currency bit coin, is a great innovation, block chain technology can be used

Tool realizes real energy Internet technology.Block chain can play a part of：First, the data based on block chain are just really
Protect and trust, the access rights protection privacy that public and private key combines, be truly realized privacy, trustworthy metering；Second, block chain is anti-to usurp
Change, coordinate trust by the way of certain between main body or force to trust, realize ubiquitous interaction under forcing to trust；3rd, block
Chain and the fusion of big data and artificial intelligence form trusted prophesy machine, sign external data, realize the self-discipline control of actual situation interaction
System；4th, the point-to-point Interactive Decision-Making of equipment room based on the deployment of block chain, it is not necessary to entrust trust in centralization platform generation
For decision-making, decentralization is so as to realizing equipment democracy and distributed determination；5th, carried out based on clearly interactive rule between each main body
Neutral benign evolution is presented in Stochastic Game, system, meets the harmony and evolvability of market law and Competition Evolutionary.
The effect of block chain is not only disintermediation.Block chain may overturn market and existing value chain, and block chain is also
New market may be createed by discharging the supply not previously developed.Energy internet will greatly promote following distribution
The development of the energy.In mains side, as a large amount of regenerative resources are installed, the randomness fluctuation of power supply will cause great choose to system
War, in load side, due to the fast development of the change of electricity consumption structure, and electric automobile, the randomness of load side and just
Property will constantly aggravate.
