Stability of distribution networks with embedded generators and induction motors

The paper investigates the collective and individual influence of synchronous and induction embedded generators (EG) on stability of a generic distribution network. With a model of the network developed in IPSA computer software package simulations were performed to determine the behavioural characteristics of the system (voltage and angular stability) with a varied mix of embedded generators, system loads and operating conditions. It was found that embedded generation collectively enhanced the overall performance whilst individually, synchronous machines offered greater benefits in comparison to the induction machines.
