Optimization of Hybrid Standalone Renewable Energy Systems by Linear Programming

Hybrid systems utilizing various renewable energy sources are well suited to satisfy the energy needs of rural and isolated areas not supplied directly by the electrical grid, especially in developing countries. This paper presents a mathematical formulation of Renewable Hybrid Sources connected together in order to build and economic System. This problem is expressed as a Linear Program where the objective function is to minimize the capital investment cost of each Renewable Energy components subject to the energy resources, size of components and energy demand. This method is general and can be applied to different locations as well as energy scenario. For illustration purposes, a numerical example combining Photovoltaic, Wind and Hydrokinetic Energy systems is provided.
