Abstract

We developed a power system stabilizer with an EDLC (electric double layer capacitor) that makes it possible to operate microgrids autonomously from utility grids, and to maintain the electric power quality in an islanded microgrid. This paper proposes two types of control systems that are composed of a PFC (power flow compensator) and a CVCF (constant voltage constant frequency) compensator. Installation locations of this system with the CVCF compensator are not limited by hardware requirements, and can maintain the quality of electricity in the islanded microgrid. Also, it is possible for the CVCF compensator to manage a dynamic load sharing function. Therefore, it is not always necessary for this equipment to have the central controller by using information networks. The EDLC is capable of charging and discharging stored electricity at a short cycle repetitively and has an advantage to keep a storage resource minimum to maintain the electric power quality. This paper shows specifications and verification results obtained by simulation studies and by demonstrating experiments of this equipment. In order to verify the practicability of the proposed control, these experiments were carried out in the microgrid that is supplying electric power to actual loads.
