Design and Simulation of an Autonomous Smart Microgrid for Energy Independence

Abstract

– The project designs a microgrid based on downtown community of El Monte city, California. The system main components include a solar PV system, a battery, a diesel generator, an inverter, a control system, and loads. The microgrid design is simulated using MATLAB Simulink. The results show that the microgrid can supply power to its community adequately and independently without relying on a utility power grid. The microgrid is smart as it can operate autonomously thanks to its automatic control system. For various operational scenarios, the microgrid proves to be resilient where it can supply its load demand successfully using its solar system, battery, and diesel generator. The load voltage is kept at satisfactory values of around 1.0 per unit. The power distribution efficiency is around 99%. The results contribute to development of smart microgrids which, in turn, improve the reliability and resiliency of large power grids, as well as provide energy independence to communities.
