Abstract: Once safety issues arise in the intelligent distribution network, it will have a significant impact on the stability of power supply. Therefore, a mode conversion based control method for the safe operation of the intelligent distribution network is proposed. Firstly, based on the structure of the intelligent distribution network, the safe operation reserve constraints are calculated and conversion strategies for multiple operating modes are generated. Secondly, considering the requirements of negative voltage offset and line load rate in the operation of the distribution network, and under the constraints of power flow, power output, compensation equipment capacity, and topology structure, a multi-stage control decision-making process is adopted to complete the safe operation control of the intelligent distribution network. The experimental results show that the control method studied can reduce the load fluctuation and overall fault rate of the distribution network, with a maximum fault rate of only 0.31%.

Keywords: mode conversion; intelligent distribution network; safe operation control; current constraints.
