Under the low-carbon background, considering the source load storage optimal operation strategy of active distribution network (ADN) is of great significance to the low-carbon, economic and stable operation of ADN. Aiming at the and voltage out of limit problem caused by high proportion distributed energy access, this paper constructs a low-carbon ADN voltage coordination and optimization model considering load demand response and stepped carbon trading, and uses second order cone programming (SOCP) to convex the model. First of all, build the ADN power flow model, model and analyze the voltage coordination devices in the ADN, build the load side comprehensive demand response characteristic model, guide the load side schedulable resources to participate in the ADN voltage coordination and optimization control, and improve the traditional condition of relying only on controllable units. Secondly, the ladder type carbon trading mechanism is introduced to build an ADN voltage coordination control model with low-carbon characteristics, to deeply explore the coordination ability of ADN voltage coordination control between economy and low-carbon, and to ensure that the system voltage is within the allowable range. Finally, CPLEX is used to solve the ADN voltage optimization model, which verifies the effectiveness and feasibility of the proposed model and method.
