Advanced Micro-Grids
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 4
Abstract
In modern society every sector needs continuous power on demand. To achieve this voltage, current and frequency, these parameters of the power system should be at rated values. Because of remote generation, transmission and distribution, we are failing to receive the reliable power. To overcome this problem, the Distribution energy sources (DES) become more suitable solution. This generated power from DES is supplied to local loads and this can be connected to the main grid through the Micro-Grid (MG). Micro-grids will operate in two modes, A Grid-connected mode and in an Islanded mode. During islanding mode, one Distributed Generation (DG) unit should share output generation power with other unit in exact accordance with the load. Need to control Real and Reactive power effectively for the load to operate without disturbance. Hence in the present work, Voltage Source Inverter (VSI) and Proportional Integral Derivative(PID) controller in power conversion process to get required real and reactive power for the normal operation of micro-grid. The proposed method has been applied to a designed test Simulink model for different types of Grid connected and Isolated modes. The simulation results obtained show that, this method can improves the reliability and smooth operation of the micro-grid system.
