Smart Microgrid Application Analysis

What is a smart microgrid?

The rise and fall of the photovoltaic industry depends on the large-scale application of photovoltaics, but photovoltaic applications can be solved without simply building a ground station or a rooftop power station. In the article “Characteristics and Construction of Smart Photovoltaic Microgrid” published on March 31, 2014, the author pointed out that photovoltaic power generation has three major disadvantages: instability, low energy density, and poor power adjustment. These three major shortcomings seriously hamper and limit The application of photovoltaic in the power supply, but to overcome these three major shortcomings, the only way is to build a smart photovoltaic microgrid. This article also introduced the structure, characteristics and technical aspects of the smart photovoltaic microgrid.

The so-called micro-grid refers to the use of photovoltaic power generation as the main power supply during the day, while simultaneously utilizing other renewable energy sources that can complement the photovoltaics to meet the power supply under different climatic conditions, using energy storage systems and including micro Gas turbines and other clean energy as a means of power supply regulation, through advanced automatic control technology and information network technology to achieve intelligent control of the network and remote scheduling between the Internet, directly within the power supply area of ​​the user load directly to the power grid. The so-called micro, refers to the comparison with the existing national grid, does not mean that the capacity is less than a specific value. Microgrids can also be connected to the utility grid.
