新能源机组大量接入电力系统和负荷快速变化引入了不确定性。为此,提出了一种基于海量历史数据,利用深度学习方式求解考虑不确定性的实时调度问题的新思路。首先,利用负荷矩阵相关性分析确定面向各调度时刻的训练样本集的基本结构;其次,基于美国PJM电力市场提出的完美调度理念,生成学习模型的训练目标,并构建各自适应学习模型的差异化训练样本集;然后,提出基于输入更新的长短期记忆(LSTM-IIU)网络,构成面向各调度时刻的实时调度自适应学习模型;最后,以WSCC 9节点和IEEE 118节点标准算例验证所提方法的可行性和适用性。与基于非线性优化理论得到的调度方案相比,文中方法能更好地对完美调度方案进行学习,提升考虑不确定性的调度能力。
The uncertainty is caused by the integration of large numbers of renewable energy units into power system and the rapid charge of load. Therefore
a new idea is proposed to solve the real-time dispatching problem considering the uncertainty by using the deep learning method based on massive historical data. Firstly
the load matrix correlation analysis is used to determine the basic structure of the training sample set for each dispatching instant. Secondly
based on the perfect dispatching theory proposed by the PJM electricity market in USA
the training objectives of the learning model are generated
and the differentiated training sample set of each adaptive learning model is constructed. Then
an long short-term memory network with internal input update (LSTM-IIU) is proposed to form a real-time adaptive learning dispatching model for each dispatching instant. Finally
the feasibility and applicability of the proposed method are verified by the standard WSCC 9-bus and IEEE 118-bus examples. Compared with the dispatching scheme based on the nonlinear optimization theory
the proposed method can better learn the perfect dispatching scheme and improve the dispatching ability considering uncertainty.
