Exergoeconomic optimisation of steam networks connecting solar-thermal dish arrays

摘要: Abstract We optimise steam network trees that connect Big Dish paraboloidal collectors to a central power block. Exergy costs, pipe material and installation costs are estimated using an exergoeconomic model used links in trees. The optimal tree is then found for 10 MW e collector field genetic algorithm. An optimised 20 network. 20 MWe has additional east–west branches not seen the 10 MWe network, reduce transport from extremities. heat loss pressure drop account approximately 60% of total cost both cases. Total are, respectively, 8.9% 9.5% potential plant revenue 10  20  networks.
