Power and Energy

High-penetrated offshore wind farms (OWFs) to power systems result in low inertia and bring large disturbances. To enhance the frequency security, this paper proposes a frequency security constrained multi-stage dispatch problem by inserting the dynamic frequency process into the unit commitment (UC) and economic dispatch (ED) framework. Firstly, the transient frequency response model of power systems considering the active frequency support of OWFs is established.

This dataset includes the system data and equivalent Distributed Energy Resource (DER) allocations for two test cases: an 11-bus system and a 240-bus radial test feeder. The 11-bus system data is based on the CIGRE Technical Report "Benchmark system for network integration of renewable and distributed energy resources," 575, 2014. The 240-bus is based on the test system described in the paper titled "A time-series distribution test system based on real utility data" by F. Bu, Y. Yuan, Z. Wang, K. Dehghanpour, and A. Kimber, 2019 NAPS Conference, 2019.

We introduce a dataset comprised of energy consumption data from smart meters in French households, capturing detailed, disaggregated time series for various home appliances. This dataset covers a six-month period with a one-minute sampling rate across five different households. The objective of this dataset is to support the development of models that learn disentangled representations of time series energy data, which can significantly enhance model generalization across both in-distribution and out-of-distribution scenarios.

Wireless power transfer (WPT) systems for electric vehicles (EVs) need to accommodate different vehicle models with varying battery voltages and Z classes, while ensuring the power, efficiency, volume, cost, and compatibility of different vehicle assemblies (VAs). To address these challenges, this article proposes a series-parallel dual rectifier architecture based on the LCC-S compensation network. The characteristics of conventional topologies are analyzed mathematically, which may have a low output power under large coupling coefficient variations.

This dataset contains the .csv files of simulation results of virtual power line operation in the Kundur four machine two area system, and the Nordic 44 test system. This includes data based on a state space model of the system, and quasi-static simulations using DIgSILENT PowerFacory. The data is divided according to figure numbers, which correspond to the figures in a paper on the very same topic that has been submitted to IEEE Transactions on Power Systems. For more details on nomenclature, units etc., please see "Instructions".

The file contains the numerical data for simulation of the application case reported in the paper "Adaptive Feedforward Grid-Forming Controls to Preserve Inertial Capabilities in Power Systems". The paper presents a novel adaptive feedforward grid-forming control, which is specifically designed to preserve the inertial capabilities of grid-forming controls without feedforward terms, and at the same time to ensure the damping capabilities provided by the feedforward grid-forming converters to the system.

In order to enable an efficient and reliable integration of photovoltaic power plants into power
grids in sub-Saharan Africa in general and Chad in particular, which is committed to massively exploiting
solar energy to address its energy deficit, this work aims to forecast hourly temperature and global horizontal
irradiation (GHI). In this study, we employ ensemble methods represented by random forest (RF) and extreme
boosting gradient (XGB) model. Their performances are then compared with the support vector regression

In the process of traction system research, the train load model is often relatively simple, and the process of multi-train operation is not fully studied. The model of flexible DC-TPSS is built, which adopts the method of traction calculation and power flow calculation. This model restores the true characteristics of trains and bidirectional converters and simulates the multiple-trains operation based on actual environment.

As the demand for clean and efficient energy solutions grows, the aggregation of large-scale Distributed Energy Resources (DERs) plays a critical role in optimizing energy systems. This dataset provides detailed parameters and configurations for a variety of DERs, including photovoltaic (PV) systems, energy storage (ES) units, combined heat and power (CHP) systems, heating, ventilation, and air conditioning (HVAC) systems, and electric vehicles (EVs).
