Optimal Voltage Stability Constrained Planning Model for Integration of Large Scale Wind Farms into Iran’s southeast Grid

Recently, the penetration of intermittent power sources has increased in power systems due to the international drive for clean and sustainable energy sources; but these alternative energies could encounter the power systems with some problems which should be planned and prevented. In this paper, based on project management consideration, a novel scenario-basis multi-objective planning method for large wind farm development plans is proposed in order to optimally minimize the wind farms’ Levelized Cost of Energy (LCOE) and total cost of power flow while maintaining the desired security margin of the grid in any state of operation. The studies are conducted on actual power system of Iran’s southeast grid using MATPOWER software and the obtained results show the effectiveness of the proposed method.
