Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The energy internet based on the block chain can construct an equivalent credible network transaction environment, and data are verified and maintained by all members in the network together, wherein all the members in the network mainly comprise two types of main bodies:
1) energy node (energy node): the energy nodes are divided into 3 types, wherein users taking small and medium-sized photovoltaic, hydraulic, wind power and other power generation equipment as energy bases can select spontaneous self-use or complementary energy to surf the internet according to self requirements, and the energy nodes are used as energy producers and consumers (prosumers) to participate in energy retail markets; users of large-scale power generation equipment represented by large-scale thermal power plants are mostly energy producers (producers) and participate in energy wholesale markets; the pure load is the energy consumer (consumer). The network composed of the producer, the consumer and the consumer participates in the whole process of sending, transmitting, changing, matching and using together and cooperates with each other. The electric power trading network is provided with a plurality of energy source nodes.
2) Energy block agent router (energy block agent router): the energy router is intelligent equipment for dynamically allocating various power resources, the energy proxy router is in the prior art, and the energy block proxy router is abbreviated as REBA。
FIG. 1 is a block diagram of a power block proxy router, wherein R is shownEBAThe logic function is divided into two parts: an Energy Routing (ER) module and a Block Processing (BP) module. In the energy routing module, standardized electrical interfaces and standardized communication interfaces connect the various subunits. In the block processing module, transaction information in the information network is collected, and the transaction information enters R after verification and confirmationEBAA local transactional memory pool, and generates a meikel tree for verification and storage. R for completion of workload certificationEBANew blocks will be generated and broadcast to other REBAAnd waiting for other nodes to verify. If not, or other REBAIf the transaction is completed first, a new round of transaction information collection is immediately carried out. A smart contract (smart contract), which may formulate transaction rules for the energy network, is triggered by an event. REBAThe whole network records the complete account book of all the specific transaction details from the creation block, is the whole node in the block chain, and can be used for independently verifying and tracing any transaction. Because the whole node has certain requirements on physical storage and communication capacity, a user can pass through REBASimplified Payment Verification (SPV) to remove restrictions and manage assets through light nodes.
On the basis, the invention provides a power resource decentralized configuration method based on user preference.
In the method of the present invention, firstly, a power resource configuration method (power resources configuration method on node preference) based on node preference is provided, and resource configuration self-adaptation is realized from the electrical energy preference perspective of the node.
The invention firstly provides an electric power transaction network (electric trade network) with node electricity utilization preference, which is hereinafter abbreviated as NET。
NETIs a six-tuple:
NET＝(G,P,R,F,T,ρ)
wherein ,
1)G＝{gi|i∈N+is a finite set of power generating cells, giIs the ith power generation unit, N+Is a positive integer set;
2)P＝{pj|j∈N+is a finite set of electricity consuming units, pjIs the J-th power utilization unit, N+Is a positive integer set;
3)R＝{rk|k∈N+is an energy block proxy routing unit REBAOf a finite set of N+Is a positive integer set;
4)F＝{fll belongs to N is a finite set of electric energy preference, wherein N is a natural number set, flA set of power preferences representing a type l;
5)T＝{tm|tm∈G×R×P,m∈N+is a power generation unit via REBATransaction set, t, for supplying energy to electricity consuming unitsmRepresenting the mth transaction path;
6) rho (G, R, P) → T is a mapping function of G, P, R to T;
in the above (4), the power preference includes at least three types, and each element of the limited set of power generation units and the limited set of power consumption units has the power preference. The preference of electric energy can be divided into three types, namely environment-friendly type, power transmission resource saving type, economical efficiency type and high efficiency type. The environment-friendly type power generation is mainly characterized by clean energy power generation, the power transmission resource saving type power transmission line loss is mainly characterized by low power transmission line loss, and the economic and efficient type power transmission line is mainly characterized by low selling price.
1) Environment-friendly type
Environment-friendly preference: the power generation environmental friendliness degree of the supplier can be reflected by the supply proportion of the clean energy in the energy supply period.
Environment-friendly preference value of power generation unit u per unit time
Wherein p, w, h and f are power generation types of photovoltaic power, wind power, water power and thermal power respectively; etotalThe total generated energy of various energy sources in unit time of the generating unit u is obtained; phi is a set of energy power generation types; lambda [ alpha ]αThe environmental pollution degree weights of different energy types;
2) power transmission resource saving type
There is often a relatively large loss of power during power distribution. Due to the rapid development of the energy Internet, the structure of the power distribution network is more complex, and the calculation of line loss is more complicated. However, in a similar network environment, the transmission distance is often positively correlated with the energy consumption. Therefore, the parameters of the power transmission resource saving preference are as follows:
preference value of power generation unit v for saving power transmission resource in unit time
Wherein N is the total number of transactions ηnThe unit distance line loss rate of the nth transaction; dnThe transmission distance for the nth transaction;
the habit of the historical distance of the transmitted electric energy within a period of time can be reflected, and the smaller the value is, the higher the resource saving performance is.
3) Economic and efficient
The electric power trading network of the invention converts the actual electricity price EPDivided into grid electricity prices ENAnd floating electricity price EFTwo parts. The former is the time-of-use electricity price uniformly released by the national grid, and the latter is a floating part which can be automatically regulated and controlled by a power supplier according to the cost and the running condition of the power supplier.
EP＝EN+EF＝EN+γEN
Where γ is a floating factor limiting the magnitude of the floating, γ ∈ (δ)1,δ2)；δ1 and δ2Respectively, the lower and upper limits of the fluctuation.
Thus giving cost-effective preference parameters: economic and efficient preference value of power generation unit w in unit timeExpressed as:
wherein ,the actual electricity price of the nth transaction at the tth moment;and the corresponding power grid electricity price is obtained.
The bidding habit of the power supplier can be reflected to a certain extent, and the smaller the value, the more economic and efficient.
In the above (6), ρ (G, R, P) → T is a power information matching method, specifically, a mapping function of G, P, R to T; the power information method is algorithmically present in a computer memory device for matching power generating units to power consuming units.
Energy consumers select one or more of the three types of electric energy supply preferences as demand preferences according to personal preferences according to specific scenes such as self living environment, power consumption requirements, economic factors and the like. Energy producers and consumers can be divided into two types of self-purchasing electricity and surplus electricity on-line according to the self electricity utilization condition, and the two types of actions belong to buying and selling, and are composite carriers with preference for supply and demand. Energy supply information provided by an energy producer is screened and filtered by EIMA (enhanced interactive authentication and authorization) and matched with a demand side to realize consensus, an optimal energy transaction object queue is formed and recommended to an electricity purchasing party, and the electricity purchasing party freely transacts according to actual demand and personal wishes to finally form an energy transaction set T.
The energy consumers belong to the electricity utilization unit, the energy producers and consumers belong to the electricity utilization unit and/or the power generation unit, and the energy producers belong to the power generation unit and can form the energy transaction set T according to the demands and the supply of the energy producers and consumers.
The method comprises the following specific steps:
1) energy-based block router REBAConnecting the intelligent device carrier for block chain and power transmission, establishing a private chain of electric energy transaction through the same founding block file, eachEnergy proxy block router REBAThe intelligent contract-based electric energy transaction rules are defined through intelligent contracts, are deployed in an energy source block chain network, and are subjected to physical information interconnection and intercommunication by an energy source agent block router REBACo-executing and maintaining.
2) Energy proxy block router REBAAnd collecting information such as energy supply plans, unit prices, electric quantities, transmission distances and line loss states during electric energy grid connection, and calculating preference types of single electric energy grid connection. When the electricity utilization unit sends a transaction request, the intelligent contract is triggered to automatically match the electric energy transaction.
3) Energy proxy block router REBAScreening out units with the same preference as the electricity utilization units from the electricity generation unit set G according to the electricity utilization preference request of the electricity utilization units through an intelligent contract, and forming a preference set SP _ List, wherein the set is a power generation unit subset;
