An Optimal Solution to The Unit Commitment Problem for A Hybrid Power System

This paper address the unit commitment problem for a power system consisted of conventional fossil power plants and wind energy farms. The main objective function to be reduced is the cost of fuel while meeting the technical and environmental restrictions such as limitation of power generation for each unit, startup cost, shut-down cost, spinning reserve, CO2 emission, wind speed limit. The artificial technique adopted to search for the optimal solution is Salp Swarm Algorithm. The suggested algorithm is utilized in a typical hybrid power system. Two cases studies are tested. The first one is for a power system free of renewable sources. The second case is for an integrated power system with a wind farm consisted 20 turbines. The obtained results are discussed.
