Power and Energy

This repository contains datasets and code with a novel numerical approach aimed at finding a distribution network expansion plan (DNEP) that prevents future congestion and voltage issues. This approach is tested using the modified IEEE 33-bus network. Electricity demand and PV production data for a leap year with a 1-minute resolution was generated using the CREST model from the Loughborough University and is provided as a dataset of future high-load and high-production scenario.


Nowadays, decentralized organization has become the emerging characteristic for AC-DC hybrid distribution systems (DS) facilitated by modern power electronic and information & communication techniques. This urges the DS to drop the centralized power supplying mode. In substitution, the DS is divided and operated as several self-adequacy subnetworks. In this paper, a two-stage Wasserstein distributionally robust optimization (WDRO) framework is proposed to provide a dynamic regionalization strategy for unbalanced AC-DC hybrid DSs.


High-capacity and large-sized batteries are widely employed in electric vehicles and energy storage systems. The surface temperature (ST) field of these batteries is usually maldistributed and unmeasurable in practice, which brings great challenges to temperature safety monitoring. Thus, this paper rebuilds the lumped thermal model and proposes a KF (Kalman filter)-MLP (multi-layer perception) joint estimation algorithm to reconstruct the two-dimensional (2D) ST field of lithium-ion batteries (LIBs).


The Illinois 200-Bus Cyber-Physical System (CPS) serves as an important case for studying risk analysis through the integration of physical and cyber components. This system designed to reflect real-world architectures. Access Complexity scores are assigned to its network edges based on the Common Vulnerability Scoring System (CVSS) Access Complexity (AC), allowing for the simulation of adversarial pathways within the system.

In order to study the principle of this control method, this paper starts from the perspective of Joule heating principle.


The efficient operation of interconnected power systems relies on Load Frequency Control (LFC) to maintain stable frequency and regulate tie-line power flow between distinct areas. In modern setups, LFC parameters are monitored and processed in real-time through cloud-based platforms, enabling centralized control and optimization. However, this introduces vulnerabilities, as demonstrated by the susceptibility to attacks such as scaling, ramp, and random manipulations of data transmitted between areas and the cloud server.


The traditional wired charging mode requiresautonomous underwater vehicles (AUVs) to be salvaged to the ship for energy replenishment, which cannot work continuously and is complicated to operate. To address this issue, since the battery voltages of AUVs are low, a convenient high-current wireless power transfer (WPT) system is introduced for the AUV batteries with low-voltage, it may cause large losses in the receiving coil and an unbalanced current-sharing issue among the rectifier diodes.


This database contains Synthetic High-Voltage Power Line Insulator Images.

There are two sets of images: one for image segmentation and another for image classification.

The first set contains images with different types of materials and landscapes, including the following landscape types: Mountains, Forest, Desert, City, Stream, Plantation. Each of the above-mentioned landscape types consists of 2,627 images per insulator type, which can be Ceramic, Polymeric or made of Glass, with a total of 47,286 distinct images.


This is the PSCAD simulation for the article "Grid Impedance Adaptive VSG Control Based on Accurate Small-Signal Modelling".


This report provides supplementary material and additional information to complement the data in the paper: “VSG-Based Power Plant Control Using System Identification and Model-Matching Techniques”. Abstract: This paper presents a control strategy for renewable power plants with converter-interfaced generation (CIG) units. Virtual synchronous generator control is used in CIG units to provide inertia and frequency support, and centralized control is proposed to achieve high-performance control of active and reactive power at the point of interconnection with the grid.
