Investigating Smooth Power Flow Control for Dispersed Generator Working Parallel to the Grid System on the Load Side

This research work investigates development of a power flow control strategy so that power flowing from utility supply side to the common load bus can be controlled economically in the presence of DG. The control of power flow from Main/utility supply and DG source to common load bus will be such that, load will not sense any king of disturbance. The studies are performed based on well known software package MATLAB/Simpower tool box. The work proposes use of static/FACT device, Unified power flow controller (UPFQ) to control power flow at load bus by utility in coordination with DG source so that response time taken by DG source to share load with utility and transients that appears in initial seconds are reduced. The work shows that Reliable, Effective and Efficient operation of DG source in coordination with main utility network is achieved using static device. Hence, the consumer is optimally benefited
