Optimal sitting and sizing of renewable energy resources in distribution network with Bi-Level optimization

This paper proposes a Bi-Level optimization to determine the optimal size and location of wind turbine (WT) and photovoltaic (PV) generator in distribution network. At first level of optimization the optimal capacity in each bus is determined without consideration of kind of technology by maximizing the profit. At second level of optimization the number of WT and PV in each bus is determined by minimizing the cost. The minimum cost is used at first level of optimization to calculate the profit.
