    • 摘要: 通过凹凸棒黏土负载TiO2-Fe3O4制备了TiO2-Fe3O4-ATP吸附剂,进行了P(V)的静态吸附和脱附实验,对其动力学和热力学参数进行了研究.通过SEM对凹凸棒黏土负载纳米TiO2-Fe3O4前后结构进行了表征,考察了物料配比及吸附时间、pH值、温度、投加量和初始浓度对P(V)吸附率的影响.结果 表明,3/4负载TiO2-Fe3O4-ATP吸附剂对P(V)有良好的吸附作用,当吸附剂质量为0.6 g,P(V)离子初始浓度0.6 mg/L时,pH为8左右,温度20°C,吸附剂对P(V)的吸附率为92.9%.吸附过程为准二级动力学,吸附类型与Freundlich吸附模型一致.TiO2-Fe3O4-ATP吸附剂在循环使用4次后,吸附率仍能达到77%以上.

    • 摘要: 目前光伏发电量预测的研究主要集中在光伏并网发电系统的发电量的方面,对家庭式PV发电量的研究较少.为在实时家庭式PV发电量序列的情况下对未来1天的发电量进行预测,提出一种基于自动分发多级分解TCN-BiLSTM-LightGBM家庭PV发电量预测模型.将各个家庭pv时序数据自动分发到各个模型中,并对时序数据进行SSA和CEEMDAN分解,将多级分解后的数据序列输入TCN和BiLSTM网络,进行分解后的时序预测,并通过LightGBM对TCN和BiLSTM预测结果进行融合,从而实现对各个家庭PV发电量的自动预测.

    • 摘要: The search for alternatives to traditional sources of electric energy opens the way for a new market in the world, and for Brazil in particular. Still in its first steps, but with immense potential, the generation of energy from solar irradiation and hydroelectric plants in hybrid systems is an important alternative. On the other hand, single source power systems, when designed to meet a particular demand without fail, lead to low market acceptance due to the availability of resources and low efficiency in performance that rewards high initial investment costs. One solution to balance and optimize energy supply is the use of more than one energy resource when sources can be complementary. Among several possible combinations reported in several studies, the hybrid photovoltaic hydroelectric system is considered to be an optimal and interesting combination. In this context, the present article makes a technical and economic pre-feasibility analysis of a hydroelectric photovoltaic hybrid system, operating photovoltaic panels on floating structures on the water surface to allow the use of the Laranjeiras dam. The study was conducted based on simulations with HOMER. The solution indicated as optimal was the installation of a hybrid energy system, implementing a hydroelectric power plant at the base of the dam, with 1497 kW of installed capacity, operating simultaneously with a set of photovoltaic modules, on the water surface of the dam, with 180 kW of installed capacity, and a power limit for the purchase and sale to the grid equal to 400 kW, to supply the demand of consumer loads up to 40 MWh per day. This combination would result in an initial cost of US$3984.885 per kW and an energy cost of US$0.026 per kWh.

    • 摘要: In the scope of solar energy-based electrical needs in rural tropical regions, the present article develops and confronts experimental power models from the using of manufacturer data and a new model made with the meteorological and electrical data acquired. These data are registered through an acquisition station around a monocrystalline photovoltaic panel, designed and realized in the scope of this work. After the acquisition of meteorological data, a choice of the most relevant meteorological variable as input vectors to express the output powers obtained was carried out. Around the Single-Diode model, seven models are performed with analytics equations, iterative methods and an optimization method with a multi-objective function to get internal parameters. The proposed experimental model is made by a combination of the solution got at STC of an iterative method, with the value of nameplate and the use of an open circuit voltage equation with experimental coefficient to predict power output in operating conditions, and it’s demonstrated more efficient. The optimization of a multi-objective function using Nonlinear Squares (NLS) through the Leveng-Marqued method to solve the parameter estimation of a PV panel has been well done and the results are useful, like classic iterative method and less time-consuming.
