摘要

由于全球寻求与技术发展有关的能源矩阵多样化,可再生能源的参与有所增加,因此需要重新设计规划和业务模式。在此背景下,本文提出了考虑风能和太阳能发电厂存在的短期调度,其中可再生能源的电力根据历史负荷分布进行分配。通过AMPL对算法进行数学建模,考虑两个不同的目标函数:(1)有功损耗最小化和(2)电力生产成本最小化。采用Knitro中的内点法对模型进行求解。对IEEE-30总线系统进行的测试使用了来自巴西电网的风能和太阳能发电场的真实发电数据,突出了该方法在可再生能源发电存在时提供充足和连贯的短期调度的能力。

Short-term Dispatch of Renewable Sources Considering Minimization of Active Losses and Generation Costs
The global search for diversification in energy matrix associated with technological developments has led to an increase in the participation of renewable sources, requiring the redesign of models for planning and operation. In this context, this paper proposes a short-term dispatch considering the presence of wind and solar plants, where the power for renewable sources is allocated according to historical load profiles. The mathematical modeling of the algorithm is performed via AMPL considering two different objective functions: (1) minimization of active power losses and (2) minimization of electricity production costs. The interior point method from Knitro is used to solve the model. Tests on the IEEE-30 bus system with real generation data from wind and solar power farms of the Brazilian Electrical grid highlight the method's capability in providing an adequate and coherent short-term dispatch in the presence of renewable generation.
