Multi-Area Dynamic Economic Dispatch Considering Water Consumption Minimization, Wind Generation, and Energy Storage System

This paper introduces a novel, practical model for Multi-Area Dynamic Economic Dispatch (MADED) problem whose primary targets are to minimize both operational cost and water consumption. To make the proposed study more practical, several additional requirements that are inevitable in forthcoming power systems are taken into account including wind power penetration, pumped storage systems, and different interconnected areas. Such a complicated problem needs to be solved by a potent multi-objective optimization tool. In this regard, one of the relatively new optimization approaches, Whale Optimization Algorithm (WOA), is implemented to solve the proposed problem. The obtained optimal solutions on a 40-unit power network illustrate the effectiveness of the proposed approach and reveal a substantial improvement in reducing the operational cost, i.e., more than $30 million is reduced annually.
