Research on the Planning Strategy and Layout Pattern of Electricity Grids in Megacities from the Perspective of Urban Planning

In light of the advancement of urbanization and the development of digital and intelligent technologies, urban power consumption has shown a continuous and rapidly increasing trend, which makes power supply and its protection key issues in terms of further urban development. Given this context, the electric power system per se has likewise been undergoing continuous improvement and change, with many efforts directed toward AC-to-DC conversion for electricity transmission. As such, the new measures applied in urban areas inevitably face the challenge with regard to coexisting with the existing urban systems. On the one hand, electricity grids, as important infrastructure of urban power supply systems, play a key role in supporting modern urban life. On the other hand, the traditional planning methods, solely relying on electricity load forecasting and load nodes, results in a certain degree of inconsistency and conflict between the electricity grid planning and the Master Urban Plan, thereby leading to serious negative impacts of the electricity grid layout on urban space quality. Given this context, this article reflected on the limitations of the traditional electricity grid layout and planning methods by analyzing the current situation and the needs of urban space development. Subsequently, relevant planning theories were combined to explore strategies and models for the planning and layout of electricity grids and related facilities in megacities based on comprehensive consideration of power security, power safety, not-in-my-backyard mentality, urban development needs, and urban space quality, in order to achieve harmonious coexistence of electricity grid construction with urban-rural space.
