This paper aims to study the impact of demand side management (DSM) technology on the operational risk of active distribution network (ADN). Firstly, a demand side integrated management model is established including energy-efficiency load optimization and interruptible load scheduling, and the active management of load resources is completed. Then the severity indicator system is established, and an ADN risk assessment method based on improved Monte Carlo simulation (IMCS) method is proposed. Finally, a risk assessment of a regional power grid is carried out. The results show that DSM can significantly improve the operational risk indicators and ensure the reliable operation of ADN.
