Multiobjective optimal load flow based on ideal distance minimization in 3D space

In this paper, three objectives of Multiobjective Optimal Load Flow (MOLF) problem -- cost of generation, system transmission loss and pollution - are considered. The MOLF problem is formulated as a multiobjective optimization problem using weighting method and a number of noninferior solutions are generated in 3D space. The optimal power system operation is attained by Ideal Distance Minimization method. This method employs the concept of an `Ideal Pointʹ (IP) to scalarize the problems having multiple objectives and it minimizes the Euclidean distance between IP and the set of noninferior solutions. This method has been applied to three IEEE standard systems.
