Application prospect analysis of distributed microgrid combined with blockchain technology under the new energy trend

Beginning this year, the country has begun to vigorously develop clean energy, a large number of wind power and solar power projects have been launched, and the problem of long-distance power transmission has also become a problem that needs to be solved. Under traditional circumstances, the electricity we use is generally alternating current, which is suitable for high-voltage and long-distance transmission, so it has been widely used. However, if new energy sources such as solar energy become popular, problems such as difficulty in accessing power and conversion efficiency may occur, such as solar energy. The electricity from the board belongs to direct current, and in this case, multiple conversions are required to normally enter the main power supply network, which indirectly increases the cost of use.

In recent years, the rapid development of blockchain and distributed technology has enabled solar and wind power generation to be well utilized, reducing costs, and at the same time improving the safety of residential electricity consumption and avoiding problems caused by power system failures.

Clean energy short-distance power transmission has become a trend

The development of clean energy has directly led to the widespread deployment of power equipment such as solar and wind energy. However, if you switch to clean energy such as solar and wind energy, you may need to invest excessively high conversion costs, deployment, operation, and maintenance costs to make clean energy. Reaching the existing commercial transmission standards will cause a large amount of input costs on the one hand, and excessive power loss in the middle on the other hand, causing a certain economic loss.

In this case, the short-distance transmission and use of electricity becomes the key. For example, it can be directly applied to households near the place of electricity production, without passing through the central grid, thereby achieving a closed loop. This will become a development trend under the popularization of clean energy. That is, the microgrid.

Blockchain + distributed microgrid transforms power transmission system

We can regard the microgrid as a short-distance, small-scale power production and use mode. In this way, lower-voltage DC and AC power can be “consumed on-site” instead of “long-distance online unified deployment” “. The main advantage of this model is that the power loss is relatively small, and the investment cost is relatively low, and due to the use of distributed power transmission technology, it can achieve the stability of residential power consumption, rather than a centralized management model.

At the same time, in terms of civilian use, due to the certain market demand for DC power, such as household electronic equipment, electric power vehicles, etc., this simple conversion method can be used directly, which can also reduce certain energy consumption problems in the process. Corresponding energy storage equipment such as central charging stations and corresponding electric charging piles in important node areas can quickly realize the effective use of electric energy, while reducing costs and ensuring the promotion and use of clean energy.

Of course, the assumption is very good, but there are still certain problems in the actual application process, such as the settlement and bidding and allocation of electricity consumption. At the same time, the distributed power grid will also form an unfavorable factor for state-owned power enterprises. Particularity, the domestic market has not yet achieved marketization, and the relevant transaction parties are still mainly based on the State Grid. Therefore, there is a certain degree of difficulty in the process of promoting the distributed power grid.

Blockchain technology can solve such problems. The biggest feature of blockchain technology is distributed accounting, which also highly overlaps with the distributed grid. Therefore, the accounting of electricity energy consumption can be realized on the corresponding nodes and completed The settlement process of electricity on the chain, so as to realize the settlement and transaction problems in the process of short-distance transmission of clean energy.

Blockchain technology is very important in this process, mainly because in the actual commercial process, electricity settlement is a complicated issue, unlike the centralized management method, if smooth settlement cannot be achieved, basically It cannot be used for real, but can only be consumed in a closed system, which also loses the basis for the wide application of clean energy.

Current status of distributed microgrids

In fact, distributed microgrids have been widely studied in many countries, but it is still difficult to commercialize them as a whole. For example, China’s National Grid had practical applications for distributed power generation applications of solar and wind energy as early as a few years ago. , The rise of blockchain has also become an important booster of distributed power grids. At present, the corresponding tests and venues have been demonstrated a few years ago, but in the actual implementation process, the early society did not pay enough attention to clean energy and economic benefits It is not good. For example, to realize the direct transmission of electricity, it is necessary to use corresponding equipment such as the Internet of Things for transmission. There are currently no corresponding standards and regulations in power settlement. At the same time, the total proportion of clean energy stations in the country is limited, so the promotion is relatively slow.

With increasing efforts to peak carbon in recent years and solar power subsidies entering the final stage, competition in the solar panel market will continue to intensify. In this case, the price reduction of equipment may further reduce the cost of installing solar power. Under this premise, clean energy will drive blockchain technology to play an important role in the microgrid, so as to achieve the needs of specific applications.

Of course, the formation of a distributed power grid is a huge project. It requires the national and local governments to cooperate and implement policies in various aspects before practical applications , such as the market-based bidding of electricity, etc. This part of the developed countries is at the forefront. , So there are certain advantages to advance. However, my country is currently conducting related tests and developments in some test areas. On the whole, distributed power grids are only suitable for small-scale practical commercial use at the application level, and there is still a long way to go for larger-scale use.
