The penetration of distributed generation (DG) has recently been increased worldwide. These DG units have excessive effects on voltage profile and losses in distribution systems. In this paper, an optimization model for active distribution systems is constructed with considering voltage deviation index and active losses. An adaptive algorithm is proposed for optimizing the weighting factors of the objective members in real time simulation so that losses are minimized without violating voltage limits. The reactive power generation capability of photovoltaic (PV) technologies, transformer taps, and dispatchable DG units are incorporated in the optimization model. Real-time simulation for the 33-bus distribution system is performed. The results demonstrate the efficiency of the adaptive algorithm for optimizing distribution systems.
