Design and Modeling for DC Nanogrids

Smart grids were constructed as a means of communication to the electric grid through computer and other information technologies. This line of communication acts as gauge for a more accurate reading of power consumed. A nano grid is a model version of a smart grid with the ability to function as separate power generator. Such feature allows for this grid to power single loads and apply for special applications. A DC-DC converter was designed to apply to a nano grid which is a form of a smart grid. The converter was a single-input-multi-output converter which is taking one dc voltage and applying it to two dc output voltages. This boost converter takes the inputs and increases its voltages, leading to the outputs respectively. The nano grid utilizes this proposed converter to carry out its special characteristics. Procedures carried out in this research showed the success of the converter. Further steps include the designing of a ring and radial architecture nanogrid to form a microgrid. A comparison of results are made showing the efficiency and reliability of ring architecture layout microgrids Doing this creates a more complex system, and provide relief to multiple sources to prevent outages

Single-Input–Multi-Output (SIMO) Converter for Nano-Grids Applications

A nano-grid is a smaller version of a smart grid with the ability to function as separate power generator. This modification to the typical smart grid allows for a system focusing on single load with using special converters. This grid takes the concept of separate loads and uses it in its ability to multiple applications. This paper exemplifies the success in the converter and its use in a nano-grid system. This positive result shows a system that is both stable and reliable in regards to power supply. A DC-DC modified converter is designed, this converter is a single-input-multi-output converter that takes the process of boosting its inputs into 3 outputs respectively of various higher voltages. Furthermore a coupled inductor process is used to reduce conduction losses as well as include soft clamping processes. This converter is implemented with the use of MATLAB/Simulink. It can be concluded that the converter has a high step-up ratio, highly efficient converter with varying output voltages
