A Novel Technique to Identify Proper Locations for Distributed Renewable Generation Integration to Minimize Contingency Impact

Abstract

this paper presents a novel technique to define proper locations for distributed renewable generation (DRG) integration to minimize contingency impact. The contingency (n1) analysis and the repeated power flow technique are used to investigate the Critical Voltage Buses (CVB). Then priority rankings are defined in two considerations, the number of impacts and voltage level at the CVB. The POWERWORLD simulator is used in this study to analyze the modified Thailand power system during peak load period. The results show that the proposed technique can identify the priority CVBs, which are the proper locations for DRG installation. With more DRG installations at the CVBs, the numbers of CVB, generator capacity and power system loss can be decreased and the load demand can be increased. This proposed novel technique can be applied effectively for the power system security enhancement.
