Service Restoration of Active Distribution Network Considering the Islanded Operation of Distributed Generation and Micro-grid

This paper proposes a novel service restoration method of active distribution network considering the islanded operation of distributed generation and micro-grid. Firstly, the islanded model with the objective function of maximizing the weighted sum of restored load considering the output power of distributed generation and micro-grid is presented. Secondly, the service restoration model with the objective function of minimizing the loads without energy supply and the power losses is established. The multi-objective model is then transferred to a single-objective model by weighted function method. And the proposed service restoration model is solved by adaptive genetic algorithm. At last, case studies are carried out on a modified IEEE 33-bus active distribution network, and the results verify the feasibility of the proposed service restoration method.
