Abstract

In the coordinated planning process of distributed generator (DG) and network structure of active distribution system

it is difficult to consider their interaction in the operation process simutaneously. To solve this problem

a mathematical model and solving algorithm for multi-agent balance of interest considering planning and operation alternative optimization are proposed. Firstly

considering demand response and operation strategy

a tri-level optimization framework and mathematical model based on the optimal cost-effectiveness of distribution network and DG are established. Secondly

the network simplification method based on topological equivalence principle is presented. Based on the in-depth analysis of the topological structure variation in the network structure generation process

a rapid generation strategy for link and loop network based on broken circle method is proposed. Then an encoding/decoding scheme of particle swarm optimization is developed. Thirdly

based on the load characteristics and demand response willingness of customers

an optimization method and operation strategy for dynamic time-of-use price are proposed

and coordinated planning solution process of the source and network considering the operation optimization is presented. Finally

the efficiency and practicability of the method are demonstrated on a practical system.
