Resiliency improvement in power distribution infrastructure employing distributed generation and switches-a review summary

The long interruption in power supply due to the naturally occurring extreme events causes very adverse impacts on the customers and essential services. In recent years, weather-related hazards have become more severe. Thus, it is very important to incorporate resiliency as an attribute of the modern distribution system to deal with such disastrous events. The application of distributed generation (DG) and automatic line switches is drawing the attention of researchers to foster resiliency planning. However, a review summary focusing on the topical part of resiliency is still beyond the scope of the practitioners and researchers. This paper highlights a strategic review of various existing techniques toward resiliency-oriented approaches. Later, an attempt was made to summarize an analytical survey on the existing research related to the application of DGs and switches to prosper resiliency in power distribution systems. This study portrays an interesting model to enable resiliency considering DG, switches, and customer power consumption patterns during natural calamities. Further, the economic aspect of local generation employment and network power loss minimization is also embedded in the planning problem. The simulation of the proposed planning model on a standard distribution network depicts an encouraging resiliency improvement result.
