Catastrophe Theory as a Tool for DG Placement Decision Making

A big promotion of distributed generation (DG) is a direct consequence of sustainable development policy in world environment and advancement in technology, therefore it is urgent to find an effective way to evaluate the DGs located at power system. A Hierarchical model for placement of DGs synthetic evaluation is present with duly consideration to the impact of environmental and economic context. A hierarchical evaluation system for power quality is also established, and it presents another method to rank the locations for DG from the perspective of the DG's influence to power quality, as indicated in the second cases in Section IV as well. Two case studies are given to show the effectiveness of the catastrophe theory.
