Introduction The smart grid is an important part of smart cities. With the construction of smart cities, the city's smart grid is ushered in a period of accelerated development. The existing urban smart grid planning pays more attention to the introduction of new technologies, and does not study in depth how to select new technologies and how to systematically apply them to smart grid construction. Method This paper attempted to construct a systematic planning method. By combing and summarizing the characteristics of smart grids in advanced cities at home and abroad, and combining the conditions of the target cities, we could find gaps and fill shortcomings, and formulate target cities' smart grid development targets according to local conditions. By comparing various aspects of power production and management, we proposed smart grid construction measures.This paper took Guangzhou Power Grid as the representative of large-scale urban power grid and analyzed the planning and construction of urban smart grid.
Result Finally, through the improvement of a series of evaluation indicators, the effectiveness of smart grid construction was illustrated.
Conclusion The large-scale urban smart grid planning method proposed in this paper is feasible and effective, and can provide guidance for the planning and construction of smart grids in other large cities.
