Research on the Enhancement Strategy of Double-loop Network Construction in Urban Core Areas

With the acceleration of urban development and construction process , as well as the integration of diversified loads and power sources, the construction requirements of urban network have also increased. Since the construction of double-loop network in urban core area, the reliability of power grid has been significantly improved. This paper explores the construction of double-loop network under three typical modes: trunk network, branch network and user access. The development direction and layout of urban distribution network in the future are defined, so as to do a good job for the construction of smart distribution network.
