Abstract
This thesis presents design and techno-economic evaluation for a Hybrid Power System (HPS), consisting of Photovoltaic (PV) system, battery bank and diesel generator power systems in addition to a one-way main grid connection. The design is based on typical collected data of the load demand, meteorological and geographical data of a typical case study. The case study is taken as construction New Talkha Nile Bridge Project in Egypt. This research provides general sizing procedures for the different components of the HPS. The design technique is effective and capable to be applied for any individual given load demand. The presented technical evaluation clarifies the major parameters affect on the performance of the utilized power systems. While, the economic analysis is based on the Life Cycle Cost (LCC), including the Net Present Cost (NPC), the annual running cost and the unit electrical (kWh) cost of each system individually. Then, various suggested operational configurations are created depending on variable percentages of the available power sources. Moreover, the current operation strategy, (diesel generators and the utility grid, if exists), is demonstrated and evaluated in a techno-economical analysis. Thereupon, an economic comparative for all operational strategies is provided with an illustrative for both the technical and economical views. An optimization process is involved and applied to determine the optimal configuration with the most cost effective for electrification the proposed load demand. The optimization techniques; developed MATLAB code with PSO and HOMER were utilized to determine the optimal HPS with the appropriate participation shares. It is concluded that the hybrid systems are more technical and economical than depending on only one power system. Moreover, it was confirmed that PV systems are more economical than diesel Genset, and the designed HPS is preferred than the current operational scenario.
