Abstract

This paper discusses the results of case studies which assess transient and small-signal stability of distributed generators connected to utility distribution networks. It also presents an investigation of the interaction between the controllers of individual generators. Case studies are based on different levels of generation penetration and a variety of operating conditions of both the networks and the generators. Transient stability and small-signal stability were assessed using commercially available power system simulation software. The interaction between the controllers is initially examined using eigen-analysis. A novel approach, i.e.individual channel analysis and design (ICAD), is then utilised to obtain an insight into the dynamics of the multivariable control problem.
