Optimization of Cogging Torque Based on the Improved Bat Algorithm
Wenbo Bai, Huajun Ran
Dec 21, 2022
Permanent magnet motors have the advantages of high output torque, high efficiency, and low noise, but the cogging effect is obvious. The 24-slot 4-pole surface-mounted permanent magnet synchronous motor is taken as an example...
A Novel Closed-Loop Clustering Method for Hierarchical Load Forecasting
Chi Zhang, Ran Li
Jan 31, 2021
Hierarchical load forecasting (HLF) is an approach to generate forecasts for hierarchical loadtime series. The performance of HLF can be improved by optimizing the forecasting model and the hierarchical structure. Previous...

While researching something else, I ran across an item in a business journal my eye ran across another item. In research this is called serendipity, something we do not hear so much about any more these days.

Load Characterization and Low-order Approximation for Smart Metering Data in the Spectral Domain
Smart metering data are providing new opportunities for various energy analyses at household level. However traditional load analyses based on time-series techniques are challenged due to the irregular patterns and large volume...
Reading Is, Like, You Know, Sooooo Gross!

Student Body Selects CSL Leadership for 2019-20
Winthrop University
Jan 01, 0001
HIGHLIGHTS Approximately 1,132 students voted in the March election, with only 16 votes separating Belton and Jackson from the runners-up. The pair ran on the platform "Be More," which will focus on cross-collaboration between...

Deep Learning for Household Load Forecasting – A Novel Pooling Deep RNN
Heng Shi, Minghao Xu, Ran Li
Sep 30, 2018
The key challenge for household load forecasting lies in the high volatility and uncertainty of load profiles. Traditional methods tend to avoid such uncertainty by load aggregation (to offset uncertainties), customer...
Phase Identification with Incomplete Data
Minghao Xu, Ran Li, Furong Li
Jul 01, 2018

Phase identification is a process to determine which of the three phases a particular house is connected to. The state-of-the-art identification methods usually exploit smart metering data. However, the data sets are not...

Prescriptive analytics for a maritime routing problem
Port state control (PSC) serves as the final defense against substandard ships in maritime transportation. The port state control officer (PSCO) routing problem involves selecting ships for inspection and determining the...
Regional nonintrusive load monitoring for low voltage substations and distributed energy resources

This paper presents a novel extension of the classic nonintrusive load monitoring (NILM) problem from household-appliance level to substation level. A new three-stage regional-NILM method is proposed to deduce the states of...

Utility-Scale Estimation of Additional Reinforcement Cost from 3-Phase Imbalance Considering Thermal Constraints
Kang Ma, Ran Li, Furong Li
Sep 01, 2017
Widespread three-phase imbalance causes inefficient uses of low voltage (LV) network assets, leading to additional reinforcement costs (ARCs). Previous work that assumed balanced three phases underestimated the reinforcement...

Quantification of Additional Reinforcement Cost from Severe 3-Phase Imbalance
This letter is an enhancement to our previous paper that quantifies additional reinforcement costs (ARCs) for low voltage (LV) assets under moderate degree of 3-phase imbalance. The original formulas cause an overestimation of...

Quantification of additional asset reinforcement cost from three phase imbalance
Kang Ma, Ran Li, Furong Li
Sep 28, 2015
Uneven load distribution leads to a 3-phase imbalance at the low voltage (LV) substation level. This imbalance has distinct impacts on main feeders and LV transformers: for main feeders, it reduces the available capacity as the...
