Aperçu de Project Overview

The national grid is shifting from centralized AC to distributed DC power generation and distribution with an increasing number of multiple-operational and variable sources and loads. The converters catering to these various terminations interact through the local or main grid. Such interaction may have an adverse impact on stability and performance. Traditional methods based on standalone converter models fail to address these issues satisfactorily, and this calls for new tools and approaches.

This project aims to develop stability analysis and control design approaches for interacted converter systems in emerging smart grids that are majorly DC. The key idea is to treat variable characteristics of terminations as discrete events or variables and capture the interactions through a connection graph model. In so doing, the entire system can be analyzed and designed under the framework of hybrid distributed systems.
