Modeling requirements to study interactions of DG and distribution systems

This presentation includes modeling requirements to study interaction of distributed generation (DG) and distribution systems. Growing requirements for high reliability of power supply have focused interest on DG and custom power devices when ride-through support is needed. When combined with the existing power grid, high reliability is possible. Even when custom power equipment is not required, DG must be used to achieve a high-reliability system The resulting impact will be a growth in DG. However, the addition of DG complicates protection schemes and associated control equipment. If not properly handled, lower reliability and even a reduction in power quality can result.
