Protection Coordination Planning with Distributed Generation (DG) and the Impactof DG on Safety, Equipment and Distribution System Operation

Driven by economic, technical and environmental reasons, the energy sector is moving into an era where

Distributed Generation (DG) will meet a large segment of increasing electrical energy demand. Local

distribution companies (LDCs) are required to accept a given percentage of customer-owned renewable DG

units in their system. Generally, DG introduces new possibilities such as shaving of peak loads and

reliability enhancement. On the other hand, DG causes a number of protection problems in the distribution

networks, such as loss of coordination, de-sensitization, nuisance fuse blowing, relay bidirectional

operation, and overvoltages. In this work, all protection problems caused by DGs will be studied. The DG

penetration level that ignites each problem will be investigated. Solutions will be suggested to avoid the

adverse effects of the DGs based on simulation results and a prototype will be built to realize the suggested

solutions.
