INTEGRATION AND OPERATION STRATEGIES FOR INVERTER-INTERFACED DISTRIBUTED GENERATION SYSTEM

This paper describes an inverter-interfaced distributed generation system that is interconnected with the electric power system. This system has two main goals: to serve customers with reliable electric power and to improve power quality. This system is interfaced through inverters because they are effective to control output voltage and current. Because DGs are interconnected with the electric power system, DGs should have countermeasures against disturbances from the electric power system. This paper proposes the operating strategy of DG in consideration for protection, islanding, and power quality. Using this operating strategy, site loads can be served high-quality power.
