Tiivistelmä
Increase of power demand and greenhouse gas emission from nonrenewable energy resources change the direction to use of renewable energy resources as micro grids. The solar and wind energy is free, infinite, and environment friendly. Due to the uncertain nature of renewable energy resources i.e. solar energy and wind energy, a system cannot depend entirely on single renewable energy resource. Therefore, a hybrid power system, with two or more renewable resources of energies is a better choice for isolated loads.
In this thesis, feasibility of hybrid power system consisted of solar panel and wind turbine energy storages and biogas generator is studied for a virtual high-rise building. Two cases were studied in this thesis work i.e. case Tampere, Finland and case Colorado, United States of America. Solar irradiance and wind speed measurements are collected for year 2016 from these two places and then energy generation is calculated and compared with electrical load required by a virtual high-rise building. Each case is divided into three subcases and one year is divided into three quarters (i.e. January to April, May to August and September to December). Hybrid power systems based on renewable energy sources can be effective option to provide continuous energy supply to electrical loads in a high-rise building. In addition, an application is developed to calculate the payback time of the hybrid power system.
Hybrid power system is based on renewable energy resources and so its CO2 generation is also less than nonrenewable energy resources. As the duration of daytime and wind speed is different around the globe, there is difference in the behavior of hybrid power system in both case studies. The hybrid power system provides a very feasible solution for energy demands of high-rise building. Solar and wind energy has become the least expensive renewable energy technologies and requires one-time investment and need less maintenance cost in existence and has attract the interest of scientists and educators the world over. Based on the results of case study, hybrid system is more feasible when compared to the installation of single renewable energy resource in case Colorado and in case Tampere, hybrid system is more effective in second quarter of the year (i.e. May to August).
