碩士 === 清雲科技大學 === 電機工程研究所 === 97 === The purposes of this thesis are to investigate the design of a multi-purpose OTEC plant (including power generation and deep sea water applications) and to build the proper power model and cost model. Under the consideration of sea water temperature changes in one year, the objective function is defined as OTEC plant cost-benefit (benefits include both electrical energy and water sales). The optimal parameter design of a multi-purpose OTEC power plant is solved by using Particle Swarm Optimization (PSO). It is expected that better cost-benefit can be obtained by using the idea of multi-purpose OTEC, except for power generation, which can also be applied to desalination, fishery, air conditioning and agriculture. The performance of PSO is compared with that of traditional Powell’s method. Test results show that the cost-benefit of multi-purpose OTEC power plant using global optimal solution of PSO is better than that of local optimal solution of Powell’s method.
