This paper adopts a proposed energy management controller in a micro grid. This micro grid integrates both a renewable energy source and energy storage systems. Photovoltaic (PV) is adopted as a main power source, a valve regulated lead acid battery, and Super-capacitor are the energy storage system. This hybrid energy storage integrates the advantages of a high energy density of the battery and a high power density of the super-capacitor to decrease the stress on the battery and to decrease the voltage change at transient conditions. The proposed controller consists of two control units. The First unit is used for …

In last couple of decades, the control of motors has increased drastically. With this increase, current control techniques are developed. In sensor-less passivity control of a DC Motor the term passivity means the property of stability in an input and output. To maintain the stability at the input side the solar pv panel is connected with MPPT which extract maximum and stable voltage. For output we simultaneously regulate, both, the output voltage of the SEPIC-converter to a value larger than the solar panel output voltage, and the speed of motor, in any of the turning senses, so that it tracks …
