The integration of Power from Rice Husk Power Plant into an Existing Weak Grid System

Abstract

This under graduate internship deals with the integration of power from rice husk power plant into an existing weak grid system. The aim of this internship is to develop and analyse a model of the power system considering husk power generation and integration with rural subtransmission grid. Power generation from rice husk energy has gained popularity in recent years all over the world, mainly because husk energy is renewable and eco-friendly. This internship has been completed to fmd the impact study of connecting a S*l-MW power generation from husk into the 33kV-sub transmission system of a utility company within the north-west part of Bangladesh. There are a total of 104 rice mills within 5 km of Dinajpur town. Rice mills in this area operate only 6 months out of the year. Husk is available at prices ranging from 2.3Tk/kg during the off season down to 3Tk/kg during peak husking season. In this internship it is found that steady state voltage changes are generally the factor which restricts the amount of power that can be connected at a certain point in the grid provided there is no restricted access in the transfer capacity. Reactive power control strategy can be used to integrate more power in the grid if the voltage limits are the deciding factor.The simulation result shows that it is possible to add a power generating subsystem in the weak grid to improve loadshedding.
