Abstract

With the transformation of the energy sector from big centralized grids and fossil fuel power stations to local interconnected grids based on renewable energy sources, accessibility to dependable energy resource is important for residential and commercial purposes. Due to the fluctuations in wind and solar energy available multiple energy sources as well as appropriate storage is needed to generate affordable electricity and heat for residential and industrial purposes. The benefits of hybrid solar and wind power with battery and hydrogen energy storage-are investigated. The study focuses on a specific location, in Lemgo, Germany under the name of KraftwerkLand, which is a pilot plant with 5 kWp photovoltaic solar panels, 5 kW wind generator and several energy conversion technologies. In the present work, an analysis with regard to the economic viability and environmental sustainability using RETScreen is performed in KraftwerkLand as a case study. The possibilities to virtually transfer the installation to other locations is shown. Combined renewable energy sources coupled with appropriate energy storage providing local energy grids are an economic environmental friendly and economically viable solution.
