Abstract :
This paper proposes a new coordinated voltage control (CVC) method with reactive power management scheme (RPMS) for a hybrid micro-grid (MG). The CVC scheme, based on synchronizing the response speeds of different voltage regulating devices, is coordinated with novel RPMS. Two cases, with and without proposed CVC, were simulated in the power system computer aided design (PSCAD)/electromagnetic transients including dc (EMTDC) environment and compared against each other. The case with proposed CVC shows superior performance, when tested for fault triggered islanding, intentional islanding, and MG internal fault. Further, the proposed CVC with RPMS is compared to a voltage regulation method present in literature. The proposed CVC with RPMS provides better voltage regulation, maximizes the fast dynamic reactive power reserve, and improves the transient response and transient stability margin of the hybrid MG.
