The Overall goal of this thesis has been to develop an optimisation method for a hydrogenbased renewable energy supply system . The cost-effective application of such a system is also analysed. The main cost intensive components, used in the System are optimised an the basis of the lifetime and the investment cost of the different components . The main cost intensive components are the renewable energy converter (REC), the battery, the electrolyser, the gas tank and the fuel cell. The sizes of the first four components are interdependent. A comparative analysis of hydrogen and diesel generator based renewable energy supply system is performed. Photovoltaic and wind energy converter is considered as energy converter and energy is supplied to a microwave repeater station. The hourly average solar radiation and wind speed for whole year as well as the load profile of the microwave repeater station is considered as input data for present optimisation method. In this optimisation method, the different components have different lifetime. It is expressed in different units. For example, the REC lifetime is expressed in year where as the battery life is expressed in füll cycles and the electrolyser and fuel cell's lifetime is expressed in terms of operating hours. In present optimisation method the battery capacity is considered in such a way that the lifetime of the system becomes integer multiple of the battery lifetime. The life of the electrolyser, the fuel cell and the tank does not end at the end ofthe system's lifetime. The cost of the components at the end of the system's lifetime is calculated an the basis of the remaining lifetime of the components, general escalation and the discount rate. [...] |
