Microgrids become a new option

"Global Meter" Information Station reported: Smart grid can realize two-way interaction between users and the power grid, allowing small and medium-sized power supplies to be connected to the power grid. In addition to using the electricity generated by users' own solar generators and other equipment for their own use, it can also be connected to the power grid for use by others.

Recently, several power supply companies in the Netherlands have made a new attempt: they have formed a small power grid with 25 households, and equipped these households with electric heating systems composed of solar panels and high-energy boilers, hybrid heat pumps, and even electric vehicles. . Users are charged based on the readings from their installed smart meters. Experimental reports show that such an operation is conducive to the optimal use of energy and reduces the burden on the power grid. This method of forming an independent power grid by several households may become a priority for providing stable power to households in the future.

Developed countries in Europe such as Britain, France, Germany and other countries have turned to plans to use wind power, solar energy and micro (small) gas turbines fueled by natural gas and other distributed power generation to gradually replace the large-scale thermal power plants and nuclear power plants currently in operation and serve as the main power generation in the future. power supply means, improve energy utilization efficiency and reduce environmental pollution.

Microgrid technology plays an increasingly important role in electric power technology. Although my country faces many challenges in the development of microgrids, with the changes in my country's fuel structure and the increasing power load during peak periods, it is necessary to accelerate the development of microgrids. technology, optimize the power supply mode and ensure the safety of power supply. In addition, from the perspective of sustainable development and environmental pollution reduction, microgrids are also an inevitable choice for our country. In general, whether from the perspective of national energy strategy and energy market, or from the perspective of user needs and power market, mini-grids provide an ideal technology and market integration solution.
