In order to adapt to the change of power generation mode and power consumption behaviour after the ac- cess of large-scale distributed generators, energy storages and electric vehicles to distribution network, the smart power utilization technology has become the research trend of current and future smart grid, based on the connotation and fundamental features of which, the application demands of flexible and optimal operation of distribution network are reviewed from the aspects of demand response, power quality control, renewable energy accommodation, optimal power flow control and improvement of equipment utilization rate. Considering the interaction between operation and planning of distribution network, the current planning thoughts and research status are summarized and analyzed from three directions of distributed generation planning, distribution network planning, and energy storage and electric ve- hicle planning. According to the challenges of distribution network operation and planning brought by the generation- grid-load flexible interaction and the development trend of future distribution network, the problems of distribution network operation and planning in the background of smart power utilization technology need to be further researched are pointed out.
