Inverter Based Distributed Generation Comprehensive Optimization For Unbalanced Power Distribution Systems

During these years, the integration of distributed generation (DG) devices has been very popular. The development of DG devices provide an opportunity to acquire better performances; for example, reducing the power loss, improving the better voltage profiles, superior energy saving function. As the novel algorithms develop, many optimization algorithms will be applied in the optimal powerflow (OPF) fields. In this paper, a multiobjective function is used to make five objects into one objective function (OF). Two kinds of DG units combination methods will be utilized. Cuckoo Search (CS) algorithm is investigated using for IEEE 123 test case. Comparing results of the two types of DG unites combination methods, it shows that placing microturbine generator (MTG) in three phases nodes and photovoltaic generation (PV) to one phase node at the end of system can play the better performance.
