Industrial electrification provides a motivation to explore new methods for electrical power management. This paper addresses the situation where the available power is not enough to meet the full demand of a large production site, which can happen b

Kernel Principal Component Analysis (KPCA) using Radial Basis Function (RBF) kernels can capture data nonlinearity by projecting the original variable space to a high-dimensional kernel feature space and obtaining the kernel principal components. Thi

Efficient disturbance detection is important for power system security and stability. In this paper, a new detection method is proposed based on a time series analysis technique known as k-nearest neighbor (kNN) analysis. Advantages of this method ar

Management of compressor degradation is often considered from the perspective of maintenance of the compressor, but most frameworks for the operation of compressors do not take degradation into account. This paper proposes a method for operation of c

A multivariate statistical process monitoring scheme should be able to describe multimodal data. Multimodality typically arises in process data due to varying production regimes. Moreover, multimodality may influence how easy it is for process operat

This paper reviews existing data-driven methods according to three criteria: the properties of the method, the impact of the systems through which the disturbance propagates on the results of the method, and the types of disturbances covered by the m

The paper discusses operation and control of a process for the liquefaction of natural gas in which the refrigeration compressors are driven by electric motors. The aim is to enable the plant to accommodate contingencies in the availability of electr

Varying production regimes and loading conditions on equipment often result in multiple operating modes in process operations. The data recorded from such processes will typically be multimodal in nature leading to challenges in applying standard dat

This paper presents a test model for investigating how to coordinate a power grid and energy storage systems (ESSs) by wide-area monitoring (WAM). It consists of three parts: first, a model of a power grid containing different types of generators, lo

Two main approaches to optimisation of load allocation for a system of compressors working in parallel rely on either minimisation of power or maximisation of efficiency. This paper shows that the two approaches are not equivalent. An example with tw
