  7. Abstract:
  8. Due to the increasing influence of distribution generation , their effect in planning can't be ignord , especially solar panels ,which are incresing rapidly. The main purpose of this thesis is to an active distribution network that annually load bus and the amount of photovoltaic production in it increases and plan dynamically. In the planning that is done , uncertanty in the amount comsumption load and uncertanty in the pattern of sunlight and also annual innterest rates in the classical system we have planned by optimizing the network expansion costs , in addition to supplying the load bus, we can keep the voltage drop bus and line filling within the allowable . To do this , we considered line over load and voltage drop bus in two ways , once as a cost function in the objective function and again as a constraint in the objective function and to consider , uncertainty the loads and uncertainty the solar panels be approximated with the normal distribution function and in planning repairs costs and maintenance , the cost of construction of lins and losses in the network has also considered and we have formed the objective function and considering the cost function in nonlinear . Finally, we performed the optimization using genetic algorithm in MATLAB software
