Abstract: Distributed energy resources are widely used within microgrid to offer optimised electricity supply to meet demand patterns in local regions. A proposed microgrid design comprising novel distribution FACTS devices is presented in this paper. The proposed design is used to stabilise the bus voltages, reduce the feeder losses, improve the power factor and mitigate the harmonic distortion. Modulated power filter compensators and green plug filter compensator are presented as AC-side and DC-side D-FACTS devices, respectively. D-FACTS devices are controlled using multi-loop error driven self-tuned PID controllers. The particle swarm optimisation is developed to optimise the self-tuning of PID controllers to achieve an effective integration of distributed energy resources technologies and to give higher microgrid performance. The results shown are generated from MATLAB simulation of the presented microgrid, where comparisons of the results with and without D-FACTS devices are presented. Results show superiority and improved performance using the presented D-FACTS.
