Research on Power Security in Key Areas of Urban Distribution Network

To solve the problem that the voltage and current of power consumption in key areas of urban distribution networks exceed the safe range of power consumption, research on power consumption security in key areas of urban distribution networks is carried out. Under the condition of the feeder N-1 criterion, the maximum power supply capacity model of the urban distribution network is established. The theory of feeder interconnection is introduced to determine the security region of the distribution network. The security response is carried out for power users in key areas, and a new power security scheme is proposed. The example proves that the application of the safety guarantee scheme can control the voltage and current in the key areas of urban distribution networks within a safe range, and improve the overall operation safety of urban distribution networks.
