The energy systems that are currently used are facing several challenges such as aging components, increase load, non-linear loads, natural and man-made disasters and cyber threats.

NWI had invested and developed energy research to improve the performance of current energy systems and investigate new technologies such as micro and smart grids to enhance future energy systems. NWI is leading research in several areas such as Phasor Measurement deployment, renewable energy, grid integration, microgrid design, simulation and development and distribution generation modeling and design.

NWI is also conducting research in energy storage system for grid and micro grid deployment. Another area that NWI is focusing on is understanding energy systems in rural areas. Because most rural communities are located far from a substation, the grids are weak. Weak grids can lead to voltage instability, brown-outs and black outs. NWI is investigating the role renewable energy and storage to improve the grid in rural communities. To solve the problems stated above, NWI has invested in advanced software and hardware tools that can model and evaluate multi-disciplinary aspects of energy systems. NWI is approaching this problem with a collaborative and diverse approach. Faculty from different disciplines such as engineering, business, communications and social science work together as a team to solve the energy problems.
