摘要: This paper develops a flexible control strategy for DG inverters in microgrid application with load current decomposition based on Instantaneous Power Theory (PQ). For grid connected mode of operation, the simultaneously supply all or part components allowing system to inject its available energy, as well work an active power filter, mitigating disturbances and improving quality. Being able total by inverter allows smooth transition between grid-connected islanded modes operation zero injection guarantee uninterrupted critical loads within microgrid. multi loop method preservation is developed regulate voltage/frequency wide range conditions. The implemented abc-frame. principles supporting are discussed analyzed offering very flexible, selective powerful system, effectiveness demonstrated through digital simulations conducted PSIM.
