Renewable energy sources(RES)such as wind turbines(WT)and solar cells have attracted the attention of power system operators and users alike,thanks to their lack of environmental pollution,independence of fossil fuels,and meager marginal *** the introduction of RES,challenges have faced the unitcommitment(UC)problem as a traditional power system optimization problem aiming to minimize total costs by optimally determining units’inputs and outputs,and specifying the optimal generation of each *** output power of RES such as WT and solar cells depends on natural factors such as wind speed and solar irradiation that are riddled with *** a result,the UC problem in the presence of RES faces *** grid consumed load is not always equal to and is randomly different from the predicted values,which also contributes to uncertainty in solving the aforementioned *** current study proposes a novel two-stage optimization model with load and wind farm power generation uncertainties for the security-constrained UC to overcome this *** new model is adopted to solve the wind-generated power uncertainty,and energy storage systems(ESSs)are included in the problem for further *** problem is written as an uncertain optimization model which are the stochastic nature with security-constrains which included undispatchable power resources and storage *** solve the UC programming model,a hybrid honey bee mating and bacterial foraging algorithm is employed to reduce problem complexity and achieve optimal results.
