Abstract-Power shortage has become the major issue inb the current scenario of the world. The consumers started generating the needed power using Distributed Energy Resources (DERs) which in turn led to the development of the microgrid. Microgrid has two modes of operation: a) grid-connected mode, b) islanded mode. In grid connected mode, the connection is established between main grid and micro grid where as no such connection exists in islanded mode and thus it operates autonomously. Microgrid may operate in islanded mode intentionally or unintentionally. Voltage and frequency in the grid are not constant due to the variable loads connected to the grid. In three phase microgrid, fault in one phase causes loss of voltage stability and in other…show more content…
VD is the voltage across the diode. VT is the thermal voltage and Eg denotes silicon band gap, n denotes p-n junction ideality factor, k is Boltzmann’s constant and q is electric charge. To increase PV Voltage solar cells are connected in series. In order to increase current they are connected in parallel. III. BOOST CONVERTER DESIGN Voltage from the micro-source is not equal to the base voltage of the line. Hence, boost converter has been designed in order to step up the voltage. The boost converter consists of components such as inductor, capacitor and switching devices whose values are given by the following equations [6]. The inductor value is Here VIN denotes the input voltage, VOUT stands for the desired output voltage, fs represents minimum switching frequency of the converter and ∆IL indicates current ripple. The inductor current ripple is Here IOUT(max) is maximum output current. The duty cycle of the switching device
