Abstract

Distributed Generation (DG) can bring support to distribution system, meanwhile, it bring unbalancedness in power source, load and line. Traditional load flow algorithms are not applicable to the weakly meshed distribution system with DGs. First, this paper present a direct algorithm based on BIBC matrix and BCBV matrix. With some improvement it is applicable to unbalanced and weakly meshed system. Then with sensitivity compensation method, this paper improve this three phase power flow algorithm, make it can deal with distribution system with DGs of wind turbines, photovoltaic system, fuel cells, storage battery, microturbines, etc.. This algorithm is proved in 33 nodes system.
