In today's electric power grids, the integration of distributed renewable energy sources gradually becomes popular with the increasing usage of them in the power system. In this study, the load-flow analysis is realized for situations participating the time-based average daily production profiles and modeled distributed renewable sources to IEEE 39 bus system. In these analyzes, the problems are revealed with the analyzing the level of intraday bus voltage, power factor, active power, reactive power and generator reactive power changes. The load-flow is realized with synchronous generator, shunt reactors and shunt capacitor connected to convenient bus of system and the eliminating of the above-mentioned drawbacks is determined.
