Technical Field
The invention relates to the technical field of electric power, in particular to a renewable energy source electric power tracking method based on a block chain in a quota environment.
Background
With the further development of distributed renewable energy power, in order to enhance the ability of a power grid to consume new energy power represented by photovoltaic power, wind power and the like, renewable energy quota systems and green certificate mechanisms are proposed in various countries of the world in succession to solve the problems of low utilization rate and the like faced by the energy sources. The renewable energy power tracking mode calculates the real proportion of renewable energy power through the analysis of power consumption composition of power users, effectively evaluates the actual consumption and quota completion conditions, and can encourage the consumption of renewable energy power at the user side. Therefore, it is necessary to build a distributed renewable energy power tracking platform in the context of quota system.
However, the distributed renewable energy sources have the problems of large quantity, wide distribution range and the like, and if the distributed renewable energy source power tracking platform is constructed in a centralized manner, the requirements of various participants on information privacy are not met, and the operation cost and the processing time are also increased due to the centralized decision-making manner. As a distributed accounting system, the distributed renewable energy power tracking platform has the characteristics of decentralization and data non-falsification due to bottom technologies such as a consensus algorithm of a block chain and the like, can maintain a trusted database without intervention of a third party by utilizing the block chain technology to construct the distributed renewable energy power tracking platform, and can realize service logic required by the operation of the platform by means of an intelligent contract.
Currently, research aiming at promoting the consumption of renewable energy power under the quota system by academic circles mainly focuses on green certificate trading and carbon trading. The block chain technology is applied to quota obligation assessment and is still in a starting stage, a distributed photovoltaic local absorption mode is researched in literature, and effective supervision of transactions is guaranteed by the block chain technology. The literature analyzes the mechanism and the necessity of carrying out excess consumption transaction at the user side, and a renewable energy consumption storage and certification system is deployed through a block chain. The block chain technology is used as a bottom-layer distributed database, and the establishment of an energy interaction platform is also one of the applications of the block chain technology in the energy field. The literature builds an electricity distribution trading platform based on etherhouses. In the microgrid, distributed resources are managed by means of a block chain technology, a mathematical model for power transaction in the microgrid is analyzed and introduced, and a block chain transaction platform is constructed to ensure the accuracy of decision making of a transaction main body and the economy of power utilization. However, from the perspective of the power composition of the quota responsible body, few documents provide a quantitative calculation method for the specific consumption of the responsible body to evaluate the actual quota completion condition, and a blockchain platform is established to manage the distributed renewable energy and the quota responsible body.
Disclosure of Invention

A renewable energy power tracking platform is built on an ether house, the consistency and the non-tamper property of data are maintained by a block chain decentralization mode, and the problem of low efficiency caused by human factors is solved by means of an intelligent contract technology. And as can be seen from comparison of examples, the real consumption of the user cannot be reflected by financial means such as green certificates and the like, the quota completion condition of the user is disconnected from the actual power consumption, and the renewable energy power tracking mode is to determine the quota completion condition of the user according to the renewable energy ratio in the power consumption of the user, so that the method has certain significance for stimulating the user to perform renewable energy consumption to complete quota system requirements.

Example 1
To verify the effectiveness of the renewable energy power tracking proposed herein, the present embodiment deploys the intelligent contract designed in the renewable energy power tracking process on an ethernet workshop as an experimental platform. Scenario setup takes a 14-node distribution network as an example, as shown in fig. 1, power consumers L1 and L2 have base loads at different times of the day, and power consumer L2 also has a certain capacity of photovoltaic installed, and nodes 5 and 12 also have distributed photovoltaic installed, assuming that all photovoltaics have similar power generation characteristics. The node 5 is equipped with a certain amount of stored energy, which is discharged during peak periods of the load and charged during underestimation periods of the load.
The renewable energy power generator and the power consumer submit a power generation and utilization request to the blockchain platform through an interface provided by a request issuing function in the intelligent contract, and transfer the Ethernet currency into the intelligent contract as a penalty amount when the quota obligation is not completed, and the result of simulation on Remix is shown in fig. 3. FIG. 3 is a table of complete information returned by the blockchain platform, indicating transaction hash values, transaction commit status, gas values of executing contracts, input and output parameters of contracts, etc. during execution of contracts.
Figure BDA0003367356050000121
The electric energy composition of the discharged electric power during the storage energy discharge period and the power consumption source of the electric power consumer and the storage energy per hour in the 24-hour period of the day are researched. And if the photovoltaic output and the energy storage output are smaller than the total basic load of the user, electricity is purchased according to the electricity price of the power grid company, and the electricity consumption behavior of the user is not influenced. Fig. 4 is a prediction situation of output and load of renewable energy power generator and power consumer, and it can be seen that the photovoltaic output time period is concentrated in 10: 00-20: 00 for a total of 10 hours. Dividing according to the load electricity utilization condition of a certain city, 08: 00-15: 00 and 18: 00-21: and 00 is the load peak time period, the stored energy is discharged, and the rest time periods are the load underestimation time periods, and the stored energy is charged.
The safety check function checks according to the power generation and utilization information submitted by the user, after the safety check is passed, the renewable energy power tracking function calculates the hourly electric energy composition of the power user, stores the hourly electric energy composition in an array corresponding to the user address in a mapping mode, and records the hourly electric energy composition by using events: the address of the user, the power consumption time and the electric energy form an array, as shown in fig. 5.
Figure BDA0003367356050000131
Fig. 6 shows the power generation and utilization of load, photovoltaic and stored energy during the day, and the power utilization composition per hour of the electric power consumer L1. 08: before 00, the load is in a valley period, the stored energy is in a charging state, the output of the photovoltaic is 0, and all the electricity of the L1 comes from the electricity purchased from the power grid. 08: 00-15: 00, the stored energy starts to discharge, and the power source of the L1 has stored energy components. 10: 00-21: when the power output of the 00 photovoltaic grid starts, the electric quantity bought into the power grid by the L1 is gradually reduced, the pressure of the power grid in the load peak period can be effectively relieved, the peak load of the main power grid is reduced, and the operation of the power grid is stabilized. Unlike L1, L2, by itself, has a photovoltaic device, 10: 00-21: the power utilization composition of 00 also comprises the photovoltaic output of the node. As can be seen from a comprehensive comparison of fig. 6 and 7, the amount of electricity purchased into the main grid during peak load periods is reduced due to the installation of distributed photovoltaic and stored energy in the distribution network.
In the load valley, the stored energy is charged as shown in fig. 8. At 08: 00 and 22: after 00 there is no photovoltaic output, the charging source of the stored energy is mainly from the electricity in the main network, in 16: 00-18: 00 has photovoltaic output, and part of the electricity in the stored energy is renewable energy power. The main components of the power discharged from the energy storage during peak load periods are shown in fig. 9, 08: before 00, all electric energy in the stored energy comes from a power grid, 08: part of the electric energy discharged after 00 without renewable energy power; at 16: 00-18: the photovoltaic output part exists in the energy storage between 00 hours, and the renewable energy components exist in the discharging components of the energy storage during the peak time at night.
And when the specified electricity generation and utilization time is reached, the renewable energy power generator and the power consumer generate electricity, and the intelligent electric meter transmits electricity generation and utilization data to the intelligent contract in real time through the interface. And calculating the consumption of the power consumer by a consumption settlement function. The energy storage part in the power utilization composition of the power consumer needs to be further split so as to obtain the actual consumption of the power consumer. Fig. 10 shows the actual consumption and quota completion of two power consumers output by the intelligent contract. The consumption of L1 is 3941kWh, the quota index completion is 26%, the consumption of L2 is 4194kWh, and the quota completion is 30%.
Figure BDA0003367356050000141
And the auditing mechanism calls a quota obligation auditing function for auditing in an auditing period, the input quantity is the account address of the user to be checked, and punishment is carried out when the quota completion degree of the user does not meet the requirement. The punishment is carried out by taking the corresponding punishment amount of 1MWh as 300 yuan, and the quota obligation index is 27%. Since the L2 has its own renewable energy source to generate power, it consumes more renewable energy source and meets the quota requirement, and the L1 does not meet the quota requirement and is subjected to corresponding punishment, and the intelligent contract execution result is shown in fig. 11.
