Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The scheme can be realized based on the terminal with the data processing capability, and the terminal can be a computer, a server, a cloud end and the like.
Next, as described in connection with fig. 1, the blockchain writing method of renewable energy generation of the present application may include the following steps:
step S110, electric energy generated by the renewable energy power generation equipment is transmitted to an inverter corresponding to the renewable energy power generation equipment.
In particular, renewable energy power generation devices are each equipped with one inverter corresponding thereto, and an edge computing device. The edge computing device can be a controller of the renewable energy power generation device, particularly can control a raspberry group singlechip of the renewable energy power generation device, and can have data processing and computing capabilities. In a power distribution network, the layout of a plurality of renewable energy power generation devices may be distributed.
The renewable energy power generation equipment can be a distributed photovoltaic array, a solar power generation plate or a small wind driven generator, and can convert primary energy into electric energy, for example, the distributed photovoltaic array can convert collected light energy into electric energy, the solar power generation plate can convert the obtained solar energy into electric energy, and the wind driven generator can convert the obtained wind energy into electric energy. The inverter corresponding to the renewable energy power generation device may be a DC/AC grid-connected inverter.
Step S120, acquiring output power of the inverter by acquiring output voltage and current information of an output end of the inverter.
Specifically, a voltage measuring instrument may be installed at the output end of the inverter to measure the output voltage of the output end of the inverter, or a current measuring instrument may be installed at the output end of the inverter to measure the current information of the output end of the inverter. The output voltage and current information can reflect the electric energy information produced by the renewable energy power generation equipment, and after the output voltage and current information is obtained, the output voltage and current information can be multiplied to obtain the output power of the inverter.
Step S130, calculating the generating capacity data of the renewable energy generating equipment based on the output power.
In particular, the power generation amount data of the renewable energy power generation apparatus may represent an amount of power generated by the renewable energy power generation apparatus during a given period of time. The power generation amount data of the renewable energy power generation device can be calculated according to the following formula:
W＝P*t
wherein W is the generated energy data of the renewable energy power generation equipment, P is the output power of the inverter, and t is the duration of a given time period.
And step S140, marking a time stamp on the generated energy data to obtain the generated energy data with the time stamp.
It will be appreciated that the time stamp of the generated energy data may represent a time value when the generated energy data is calculated, and may represent the generated time information of the renewable energy power generation apparatus, so that the data information is provided to the respective blockchain nodes of the blockchain network with higher reliability when being written to the blockchain for verification.
Specifically, the generated energy data may be time-stamped by a device having a clock synchronization function.
And step S150, carrying out data encryption and digital signature on the generated energy data with the time stamp to obtain generated energy encrypted data, and writing the generated energy encrypted data into a target blockchain node in the blockchain network.
The blockchain network can be built based on an open source alliance blockchain platform and can be operated based on a Ubuntu 20.04 system. The blockchain network may employ federated blockchain techniques to reduce computation on blockchain links and improve blockchain throughput.
Specifically, the generated energy data with the time stamp can be subjected to data encryption and digital signature through the edge computing equipment corresponding to the renewable energy power generation equipment, and the obtained generated energy encrypted data is safer and more reliable, so that the generated energy encrypted data is more reliably recorded when being written into a target blockchain node in a blockchain network, and the credibility requirement of providing auxiliary services for a power grid is met.
It can be appreciated that the blockchain network may include a plurality of distributed blockchain nodes, and each blockchain node may correspond to the generated energy data of each renewable energy power generation device for the service of writing the generated energy of the renewable energy, so that the blockchain network may uniformly record and manage the generated energy data of each renewable energy power generation device.
According to the blockchain writing method of renewable energy generating capacity, electric energy generated by renewable energy generating equipment is transmitted to an inverter corresponding to the renewable energy generating equipment, output voltage and current information of an output end of the inverter are collected to obtain output power of the inverter, generating capacity data of the renewable energy generating equipment is calculated based on the output power, a timestamp is marked on the generating capacity data to obtain generating capacity data with the timestamp, data encryption and digital signature are carried out on the generating capacity data with the timestamp to obtain generating capacity encryption data, and the generating capacity encryption data are written into a target blockchain node in a blockchain network. Therefore, after the generated energy data is obtained, the generated energy data can be marked with a time stamp, the data recording precision of the generated energy data is improved, and the generated energy data is subjected to data encryption and digital signature before being written into the blockchain, so that the written generated energy data is safer and more reliable.
In some embodiments of the present application, a process of timestamping the generated energy data to obtain timestamped generated energy data in step S140 may include:
and marking a time stamp on the generated energy data through a similar phase measuring module to obtain the generated energy data with the time stamp.
It is understood that in the present distribution network, a smart meter equipped with a synchrophasor measurement unit is adopted, which has a wide area synchrophasor measurement function, but considering the cost of such a smart meter, it is difficult to install in a large scale in the distribution network, so that it is difficult to precisely meter the amount of electricity generated by the renewable energy power generation device after the renewable energy power generation device is generally connected to the meter by the existing power grid side measurement equipment. The phase-like measurement module can comprise a GPS synchronous clock module which can be applied to wide-area synchronous measurement and can have a GPS synchronous clock function. Because the cost of the similar phase measuring module is far lower than that of the intelligent ammeter, a plurality of similar phase measuring modules can be respectively connected with each renewable energy power generation device, and therefore the accurate measurement of the generated energy of each renewable energy power generation device is realized.
According to the blockchain writing method for renewable energy generating capacity, the generating capacity data are marked with the time stamp through the quasi-phase measuring module, the generating capacity data with the time stamp are obtained, the cost of the intelligent ammeter with the synchronous phasor measuring unit is saved, meanwhile, the accurate measurement of the generating capacity of each renewable energy generating device is achieved, and the requirement that renewable energy generating equipment participates in auxiliary service and needs to be checked is met.
In some embodiments of the present application, a process for writing generated energy encrypted data to a target blockchain node in a blockchain network as referred to in the above embodiments is described, where the process may include:
s1, broadcasting each block chain node in the block chain network, and sending digital signatures of generated energy encrypted data to each block chain node.
It can be appreciated that the blockchain network has the characteristics of distributed type, high security and distributed type, when the generated energy encrypted data needs to be added into the blockchain network, each blockchain node needs to be initiated to audit the generated energy encrypted data, and the digital signature of the generated energy encrypted data can be verified specifically so as to verify the security of the generated energy encrypted data newly added into the blockchain network.
Specifically, when the generated energy encrypted data needs to be written into the target blockchain node, the blockchain network can execute a preset intelligent contract, trigger broadcasting of each blockchain node of the blockchain network, send the digital signature of the generated energy encrypted data to each blockchain node, and each blockchain node can verify the digital signature to obtain a verification result.
Each blockchain node can verify the digital signature according to the verification mode of the blockchain node, and the verification result of each blockchain node can represent the result that whether the blockchain node considers the digital signature to be safe or not and whether the digital signature is trusted or not.
And S2, when the verification result of each block chain link point on the digital signature meets a preset condition, writing the generated energy encrypted data into a target block chain node in the block chain network.
Specifically, the preset condition may represent a condition that the blockchain network verifies the digital signature of the generated electricity encrypted data, or may represent a verification passing condition specified by an intelligent contract adopted by the blockchain network.
It will be appreciated that, since each blockchain node verifies the digital signature to obtain a verification result pertaining to that blockchain node, when there are multiple blockchain nodes in the blockchain network, there are a corresponding number of verification results. The first is that all the verification results pass verification, the second is that all the verification results fail verification, and the third is that part of verification results pass verification and part of verification results fail verification, then preset conditions can be set, the preset conditions can be related to the proportion of the verification results, if the passing rate of each block link point to the digital signature is not lower than the preset proportion, the preset proportion can be 1/2 or 2/3, and can be customized, and therefore when the verification results of each block link point to the digital signature meet the preset conditions, the generated energy encryption data can be written into the target block link point in the block link network.
For example, when the preset condition is that the passing rate of each blockchain node to the digital signature is not lower than the preset proportion, and the preset proportion is 50%, if the passing rate of each blockchain node to the digital signature is 60 out of 100 blockchain nodes in the blockchain network, the passing rate of each blockchain node to the digital signature is higher than 50%, then the generated encrypted data can be allowed to be written into a target blockchain node in the blockchain network, if the passing rate of each blockchain node to the digital signature is 40 out of 100 blockchain nodes in the blockchain network, and the passing rate of each blockchain node to the digital signature is lower than 50%, then the message of refusing to write into the target blockchain node can be sent to the terminal requesting to write into the target blockchain node.
According to the blockchain writing method of renewable energy generated energy, when the generated energy encrypted data is written into the target blockchain node in the blockchain network, each blockchain node of the blockchain network can verify the digital signature of the generated energy encrypted data, and after the digital signature reaches the preset condition, verification is confirmed to pass, the generated energy encrypted data is allowed to be written into the target blockchain node, the safety of the data written into the blockchain is improved, and the safety and credibility of the generated energy data written into the blockchain network are indicated.
Considering that the essential function of the renewable energy power generation device is to convert primary energy into electric energy, and to make full use of the electric energy, the inverter may make full use of the electric energy of the received renewable energy power generation device, in some embodiments of the present application, a process for distributing electric energy to the inverter is described, where the process may include:
s1, converting direct-current electric energy into alternating-current electric energy through an inverter.
It is understood that, after the renewable energy power generation device converts primary energy into electric energy, the electric energy is in the form of direct current electric energy, and electric energy required to be consumed by most electric equipment is alternating current electric energy, so that the direct current electric energy can be converted into alternating current electric energy.
S2, inputting alternating current power into a power grid through an inverter.
In particular, the power grid may be a power grid to which the renewable energy power generation device is connected.
According to the blockchain writing method of the renewable energy generating capacity, after the inverter obtains the electric energy of the renewable energy generating equipment, the direct-current electric energy is converted into alternating-current electric energy and is transmitted to the power grid, so that the electric energy is fully utilized.
