Abstract

Distributed generation, or DG, involves utilization of small generators that are distributed in a power network, to supply the electric power demands of utility customers. This paper presents the analysis of droop based generation control schemes for DG inverters comprising of active power-frequency and reactive power-voltage controllers. This enables decentralized operation with load sharing in a microgrid containing several interconnected DGs. Small-signal models are developed for microgrids consisting of several DGs connected in a chain topology. Mathematical propositions for stability are developed and guidelines are provided for design of controllers to meet the IEEE P1547 performance specifications.
