Optimal planning of wind—diesel generation units in an isolated area

Abstract This paper proposes a technique for computing the actual output energy of different combinations of a wind energy—diesel engine system. Three different generation procedures for an economical wind—diesel engine system for supplying the load requirements of an isolated area are also studied. A non-linear programming technique is performed to optimize the combination of wind—diesel generation units to meet the load demand. The suggested technique is applied numerically to choose the most economical model from the different wind energy machines installed at a site in Egypt on the Mediterranean coast. In addition, an optimal generation procedure for the economical wind—diesel engine system of a recently constructed village at the considered site is introduced. The percentages of wind energy and diesel engine energy to feed a specified load at minimum cost within the system operation constraints are deduced.
