Microgrid: a limited complement to the traditional power grid rather than an impact
Post time: 2024-12-12
First of all: from the overall development trend, microgrids will not be adopted in large numbers
Although microgrids have certain advantages in some specific scenarios, traditional power grids still occupy a dominant position in most cases. After long-term development and improvement, the traditional power grid has formed a huge and stable power supply system, which can meet the electricity demand of the vast majority of regions.
Analysis from the power generation side: microgrid is only suitable for situations where local energy is relatively sufficient
If a region is very rich in energy resources, then you can consider the construction of microgrids to achieve efficient use of local energy. For example, in some areas with abundant wind resources, wind power microgrids can be built; Where solar energy is abundant, solar microgrids can be developed. However, if the energy is too abundant, a direct grid connection to the traditional grid may be a better choice, so that the excess power can be transferred to other places where it is needed to achieve the optimal allocation of energy. On the other hand, if the local energy is not sufficient, then the microgrid cannot be established at all, because there is no guarantee of a stable power supply.
From the point of view of the power side: microgrids are only suitable for relatively remote places
In remote areas that are far from the coverage of traditional power grids, the construction of microgrids can solve local power problems. Due to geographical constraints, connecting these areas to the traditional power grid can be prohibitively expensive or technically difficult. But in places that are not remote, there is already complete coverage of traditional power grids, and there is no need to build microgrids.
Think of it in terms of cost
If a place is not of strategic value, such as a garrison island or a specific area where large-scale electricity consumption is expected, it is impossible to build a microgrid. The power grid is an infrastructure strictly controlled by the state, and its construction and operation require a lot of capital and technical support. Unlike the Internet industry, it is not easy to get a lot of investment because of a concept. The construction and maintenance of traditional power grids is based on the country's overall energy strategy and people's livelihood needs and have long-term stability and reliability. The construction cost of microgrids is relatively high unless, in the special strategic needs, it is difficult to get large-scale promotion.
Analogy to IT microservices: Microgrids and IT microservices are not the same thing at all
IT microservices are made in a large service center, such as Ali Cloud, Amazon Cloud, and other resources to achieve flexible service combination and expansion. The microgrid is equivalent to developing a set of small service centers by itself, which requires independent construction of power generation, energy storage, distribution, and other facilities, and its complexity and cost are much higher than that of IT microservices.
At present, although the photovoltaic and wind power plants around the world belong to the category of microgrids to a certain extent, they are actually more of a product of the transitional stage of The Times. Unless the energy storage technology is greatly improved, these new energy generation methods can only increase GDP and employment to a certain extent, and cannot fundamentally replace the traditional power grid.
In the future, nuclear fusion technology may be the fundamental way to solve the energy problem. Nuclear fusion can provide a large amount of clean energy, once the commercial application, completely changes the global energy landscape.
Therefore, from the above points of view, the microgrid will not have an impact on the traditional power grid in the future, and it is more to play a complementary role in specific scenarios. We should look at the development of microgrids objectively, fully recognize their limitations and advantages, and make reasonable use of microgrid technology to contribute to the sustainable development of the energy field.
