Hedging Price Risk Using Contracts for Difference with Volume Uncertainty
Journal of Electrical Engineering & Technology - - Trang 1-8 - 2024
Donghyuk Choi, Hojeong Park, Hunyoung Shin
Energy market instability due to global geopolitical tensions has led to increased volatility in the electricity spot market, increasing financial risk for market participants. As a result, it is now more crucial than ever to investigate into strategies to protect against price volatility in the market. This study aims to provide a comprehensive analysis of how Contract for Difference (CfD) impact...... hiện toàn bộ
A Modified Hybrid PDA/FIR Localization Algorithm for Wireless Sensor Network
Journal of Electrical Engineering & Technology - Tập 19 - Trang 681-693 - 2023
Cheng Long, Jiahe Song
In indoor localization based on wireless sensor networks, due to the complex and changeable indoor environment, the propagation of wireless signals will be interfered by obstacles and walls to produce errors, which is called non-line-of-sight (NLOS) error. Although the probability data association (PDA) filtering algorithm is one of the most successful positioning algorithms in line-of-sight, the ...... hiện toàn bộ
Soft Start Analysis of Induction Motor Using Current Phase Angle
Journal of Electrical Engineering & Technology - Tập 17 - Trang 1475-1480 - 2021
Jong-Gyeum Kim
Compared to other electric motors, induction motors can ensure convenience of maintenance, robustness and fast speed start-up characteristics, and are widely used in places where rotational force is required. Despite these various advantages, the voltage drop caused by high current during starting is the biggest problem. The voltage drop can make the operation of the motor itself as well as other ...... hiện toàn bộ
Analysis of Influence Factors on AC Breakdown Characteristics of Rod-Barrier Gap and Electric Field Simulation

Analysis of Multi-Input Multilevel Boost Inverter Circuit with Optimal Firing Angles Using dSPACE
Journal of Electrical Engineering & Technology - Tập 18 Số 2 - Trang 1135-1145 - 2023
Ponraj, Ram Prakash, Sigamani, Titus, Ravindran, Vijay
The DC load utilities are increased due to the modern development of alternate renewable Energy sources and Electric Vehicles. Contemporary applications like Electric Vehicles require multiple voltages that require separate DC-DC converters. Usage of more power electronic converters for multiple loads leads to more harmonics and high switching loss. To minimize the losses and improve efficiency, t...... hiện toàn bộ

Performance Enhancement for Microgrids Under the Demand Uncertainties with the Presence of Multiple DGs Through Stochastic Ranking Algorithm
Journal of Electrical Engineering & Technology - Tập 16 - Trang 223-238 - 2020
Thiruvenkadam Srinivasan, Xiancheng Wang, Hyung -Jin Kim, In-Ho Ra
The integration of Distributed Generators (DGs) in the reconfigurable microgrid is evolved to enhance the power delivery performance. The DGs are categorized as controllable and uncontrollable based on their power generation control behaviors. In addition to the control behavior, under the uncertain conditions of the microgrid, the performance of DGs is limited due to their respective drawbacks. T...... hiện toàn bộ
