Abstract :

This paper deals with a multi-objective optimization problem with conflicting objectives aims to find the best compromise tradeoffs among the feasible solutions in the search space. These kinds of solutions are known as non-dominated solutions or Pareto solutions. In the test system two wind turbines, one fuel cell and two photovoltaic arrays have implemented to optimal the system operation under two conflicting objective function. The first power quality improvement and second the minimization total cost. The power quality index which considered in this research is deviation of the bus voltage concept. Using NSGAII application, the Pareto set, the best compromise solution is selected according to the fuzzy based decision ranking.
