In this paper the features of hybrid CSP – Waste power plants are evaluated as a function of the location. The process integrates waste and concentrated solar within a combined cycle. The model is solved as a non-linear optimization problem within a multiperiod scheme to decide on the contribution of the energy resources and the operating conditions of the facility to meet a demand of 25 MW over a year as a function of the resource availability, solar and waste. Urban and rural areas of 5 different regions are considered selecting different types of waste, cattle and pig manure in rural areas and sludge and organic municipal solid waste (OMSW) in urban areas. The results yield that cattle slurry is selected over pig manure and OMSW over sludge. Only rural areas have enough waste to meet the demand constantly. Reaching the demand represents more than 50% additional investment on waste processing units. As a result, to ensure meeting the demand the cost of electricity increases by 30% compared to a CSP plant that produces following solar availability.

混合CSP垃圾处理厂的现场特定过程设计

在本文中,将混合CSP –垃圾发电厂的功能作为位置的函数进行评估。该过程在一个联合循环中整合了废物和集中太阳能。该模型作为多周期方案中的非线性优化问题进行求解,以决定能源的贡献和设施的运行条件,以满足一年中25 MW的需求,这取决于资源的可用性,太阳能和浪费。考虑在5个不同地区的城市和农村地区选择不同类型的废物,农村地区的牛和猪粪以及城市地区的污泥和有机城市固体废物(OMSW)。结果表明,选择牛粪浆优先使用猪粪肥,选择OMSW优先选择污泥。只有农村地区有足够的废物来不断满足需求。达到需求意味着对废物处理单元的额外投资超过50%。结果,与满足太阳能需求的CSP工厂相比,为了确保满足需求,电力成本增加了30%。
