| Abstract |
Traditional distribution power grid planning for smart cities is usually based on the expansion of future cities. However, as the aging problem of the world's population combined with the global economic recession in recent years, it is important to gain a planning strategy not only for developing cities but also for shrinking cities as well. This paper first designed an evaluation index to evaluate the future development level for different cities, for which factors such as population, economic, political problems and power grid are considered. Second, the cities are divided into three secondary-level categories which are expanding, moderate developing, and shrinking based on the evaluation method. Additionally, these categories are further divided into third-level categories based on the combination of raising and falling in Gross Domestic Product (GDP), population and power consumption. Last, a suggested distribution power gird planning method is provided for different types of cities as a reference for power engineers around the world. Also, factors such as renewable energy and electric vehicles are considered. By applying this planning technology, a safe, efficient and sufficient power grid can be built for different development types of cities. © 2022 IEEE. |
