摘要

发电站的故障变量与天气、物理结构、控制和负荷行为等方面有关。由于其不可预测的特性,预测时间性电力故障非常困难。由于通常要求高精度,短期时间预测的故障估计非常困难。本研究提出了一种将随机行为转换为稳定模式的方法,这种模式随后可用于短期估算。在这种转换中,采用了 K 均值聚类,然后使用长短期记忆和门控递归单元算法来进行短期估算。环境、运行和生成的信号因素都是通过数学模型模拟的。天气参数和负荷样本已作为数据集的一部分收集起来。使用 MATLAB 编程进行蒙特卡洛模拟,对故障进行实验估算。然后将实验估计的故障与实际的系统时间故障进行比较,发现两者非常吻合。因此,为了填补未来电网故障估计方面的知识空白,本文所取得的成果为电网未来故障估计试验台奠定了良好的基础。

Temporal forecasting by converting stochastic behaviour into a stable pattern in electric grid

The malfunction variables of power stations are related to the areas of weather, physical structure, control, and load behavior. To predict temporal power failure is difficult due to their unpredictable characteristics. As high accuracy is normally required, the estimation of failures of short-term temporal prediction is highly difficult. This study presents a method for converting stochastic behavior into a stable pattern, which can subsequently be used in a short-term estimator. For this conversion, K-means clustering is employed, followed by long-short-term memory and gated recurrent unit algorithms are used to perform the short-term estimation. The environment, the operation, and the generated signal factors are all simulated using mathematical models. Weather parameters and load samples have been collected as part of a dataset. Monte-Carlo simulation using MATLAB programming has been used to conduct experimental estimation of failures. The estimated failures of the experiment are then compared with the actual system temporal failures and found to be in good match. Therefore, to address the gap in knowledge for any future power grid estimated failures, the achieved results in this paper form good basis for a testbed to estimate any grid future failures.

期刊介绍: This Journal is established with a view to cater to increased awareness for high quality research in the seamless integration of heterogeneous technologies to formulate bankable solutions to the emergent complex engineering problems. Assurance engineering could be thought of as relating to the provision of higher confidence in the reliable and secure implementation of a system’s critical characteristic features through the espousal of a holistic approach by using a wide variety of cross disciplinary tools and techniques. Successful realization of sustainable and dependable products, systems and services involves an extensive adoption of Reliability, Quality, Safety and Risk related procedures for achieving high assurancelevels of performance; also pivotal are the management issues related to risk and uncertainty that govern the practical constraints encountered in their deployment. It is our intention to provide a platform for the modeling and analysis of large engineering systems, among the other aforementioned allied goals of systems assurance engineering, leading to the enforcement of performance enhancement measures. Achieving a fine balance between theory and practice is the primary focus. The Journal only publishes high quality papers that have passed the rigorous peer review procedure of an archival scientific Journal. The aim is an increasing number of submissions, wide circulation and a high impact factor.
