Integrated Resource Optimizing Planning and Allocation Method of Intelligent Distribution Network for Differentiated Demands of Users

Considering the operation reliability and power demand response in the planning of active distribution network can stabilize the impact of distribution generation (DG) penetrating on power grid effectively.This paper introduces the demand response cost and the reliability constraint of power grid operation based on the traditional model of active distribution network, and builds a comprehensive resource planning model for intelligent distribution network, which is oriented to the different needs of users.The evolutionary algorithm was adopted to solve the model, and the planning scheme of active distribution network was obtained with considering the reliability of power grid operation and demand response.Based on the case study of IEEE 33-node system, the results show that the proposed planning can effectively reduce the total cost during the planning period, and provide the decision basis and method reference for the active distribution network planning.
