specific Embodiment approach 1

[0028] Specific implementation mode one: combine Figure 3 to Figure 9 Describe this embodiment, a distributed energy generation and energy storage system based on blockchain transactions described in this embodiment, the energy storage system realizes the power transfer and asset transfer between buyers and sellers through the energy storage battery combination 5 and the blockchain transaction system transfer;

[0029] The energy storage battery combination 5 operates as a transitional power supply. When the electric energy generated by the distributed energy exceeds the demand of the load electrical appliances, the excess electric energy is stored by the energy storage battery combination 5; When there is a demand, power is supplied by the energy storage battery combination 5;

[0030] The blockchain trading system includes a bidirectional inverter charging and discharging control cabinet 3, a PMU energy management unit 4 and a smart meter 7;

[0031] The bidirectional inv...

specific Embodiment approach 2

[0049] Specific embodiment 2: This embodiment is to further limit the distributed energy generation and energy storage system based on block chain transaction described in specific embodiment 1. In this embodiment, the block chain transaction system includes Including DC / DC inverter control cabinet 1;

[0050] The DC / DC inverter control cabinet 1 is provided with a DC / DC module and a No. 1 MPPT controller;

[0051] The electrical energy output by the photovoltaic generator is regulated through the DC / DC module, and then continuously tracked and controlled by the No. 1 MPPT controller, so that the electrical energy output by the photovoltaic system is output to the DC bus at the maximum power state.

[0052] In this embodiment, the electric energy output by the photovoltaic generator is unstable electric energy, which will fluctuate due to the influence of objective factors such as weather, so the output electric energy is regulated through the DC / DC module, and then passed thr...

specific Embodiment approach 3

[0053] Specific embodiment three: This embodiment further defines a distributed energy generation and energy storage system based on blockchain transactions described in specific embodiment one. In this embodiment, the blockchain transaction system also includes AC / DC rectification and inverter control cabinet 2;

[0054] The AC / DC rectification and inverter control cabinet 2 is provided with an AC / DC module and a No. 2 MPPT controller;

[0055] The electric energy output by the wind turbine is rectified by the AC / DC module, and then continuously tracked and controlled by the No. 2 MPPT controller, so that the electric energy output by the wind turbine is output to the AC bus at the maximum power state.

[0056] In this embodiment, due to the influence of wind fluctuations, the voltage and frequency of the wind power generator's electric energy are in a fluctuating state, so the output electric energy is rectified by the AC / DC module, and then continuously tracked and controll...

Abstract

The invention discloses a distributed energy power generation and energy storage system based on blockchain transaction, relates to a distributed energy power generation and energy storage technology,and aims at solving the problems that existing distributed energy power generation is poor in stability, high in regulation and control difficulty and poor in safety and credibility in the electric energy transaction process. According to the energy storage system, by means of the energy storage battery combination, the blockchain transaction system is used for optimizing the client of a user, amulti-energy complementary electrical connection mode is adopted for connection, and meanwhile power transfer and asset transfer of a buyer and a seller are achieved on the basis of a physical topological structure of transaction of distributed energy P2P. The system has the beneficial effects that the stability of distributed energy power generation is improved; the transaction electric energy has the characteristics of high stability and high safety.

Description

technical field [0001] The invention relates to a distributed energy generation and energy storage technology. Background technique [0002] With the development of the Energy Internet, distributed energy such as solar energy and wind energy has the advantages of less pollution, high energy conversion rate, high operational reliability, small equipment size, and convenient and flexible installation. Therefore, distributed energy has gradually become an important aspect of power generation. source; however, it has unstable power generation and difficult regulation, which also makes it more difficult to trade freely in the market. [0003] Existing market entities mostly adopt a centralized model when conducting transactions between them: power generators and users upload data to the central processing system, and match power generators and consumers through centralized matching or optimization. However, with the rise of distributed energy sources of various types and quantit...
