Novel Approach for Optimal Sizing of Stand-alone Hybrid Photovoltaic/Wind Systems


Science and research, Islamic Azad University, Kerman, Iran


Nowadays using of new energies in the form of dispersed resources in the worlds is wide spreading. In this article we will
design a dispersed production source in the form of a solar/wind hybrid power plant in order to supply the energy of a residential
unit according to a sample load pattern. The aim of aforementioned design is to reduce its costs in a period of 20 years. In order
to optimize system costs we will use a new algorithm which is based on collective intelligence namely gravitational search
algorithm and also we will use particle swarm optimization algorithm. At the end of the article we will present anemometry
and radiation data which is collected from an area in Ardebil and Mashhad, note that these data is optimized based on our
suggested algorithm. Finally we can conclude that with an appropriate design of dispersed production resources we will be
able to effectively reduce costs and make renewable energy usage more economically.
