Abstract
The development of demand response (DR) technology provides a new approach for the optimal removal of controllable load in the distribution network. The traditional load shedding scheme is relatively extensive, the load power is directly cut off in this scheme, which will worsen the relationship between power grid companies and users. In this paper, an active distribution network (ADN) load shedding model considering user satisfaction is proposed. Taking the maximum user satisfaction and the minimum distribution network DR cost as the objective function, the min-max standardization method is used to simplify the multi-objective function. The second-order cone relaxation technique is used to linearize the original mixed-integer nonlinear model and establish a mixed-integer second-order cone programming model. The results show that the multi-objective active distribution network load shedding model can effectively reduce the DR cost and improve the voltage stability.
