Improving the Electricity Network Resilience by Optimizing the Power Grid

A complete smart grid network is modeled and evaluated within two grid levels. The Microgrid Evaluation tool is used for the low-level voltage microgrid where the topology is detailed down to buildings and their assets. Outages of arbitrary duration are simulated to identify the microgrid's capability to reduce consumption through demand management and interruptible load mechanisms. In contrast, the mid-low voltage level grid is simulated using an overall grid modeling tool in which power plants, lines, stations (SCADA), current breakers, and localized generators are subject to simulated failures. The energy balancing optimization based on the cost minimization function is presented for normal and outage contingency grid operations. Overall, the tool evaluations provide the architectural basis for the evaluation of the effect of outages in two different levels of the grid.
