Optimal Power Flow under Variable Wind Generation

In this paper Optimal Power Flow (OPF) problem is solved for a power system, which includes wind power as an additional generation input under variable load conditions. The fixed‐speed Wind Turbine Generator (WTG) option is considered in this study: simulations have been performed for various sizes of wind farm attached to the IEEE 30‐bus systems using the DIgSILENT Power Factory simulation software and all simulations used the DIgSILENT package. The main conclusion is that a fixed‐speed wind farm generator is effective in minimising the losses and the total generation cost as well. IEEE 30‐bus system is considered to demonstrate the suitability of the proposed approach for solving the OPF problem.
