Accurate and Fast Load Estimation Under Detuned Operation of IPT Systems Hani Savaedi, Seyed Saeid Heidari Yazdi, Mehdi Bagheri, Alireza Namadmalan International Journal of Circuit Theory and Applications, 2025 This paper introduces an accurate and easy‐to‐implement algorithm for estimating the mutual inductance and load for inductive power transfer (IPT) systems. The algorithm employs a modified fundamental harmonic analysis (MFHA) and takes into account models of the battery and output filter. Using this algorithm, mutual inductance, output power, and the instantaneous voltage of the battery are predicted with less than 5% error. The formulations are presented for a series–series IPT system and generalized for non‐symmetric conditions, meaning when the primary and secondary sides have different resonant frequencies. The proposed estimation method has been verified by different sensitivity analyses and simulations, using MATLAB and PSIM simulators. To validate the proposed algorithm, a laboratory prototype with operating frequencies of 82 to 85 kHz and maximum output power of 200 W was implemented and the accuracy of the estimations has been verified under different output power and operating frequencies for both symmetrical and non‐symmetrical conditions.
Design and Implementation of Underwater Inductive Power Transfer Systems With An Accurate Eddy Current Loss Model Approach Sadjad Shafiei, Seyed Saeid Heidari Yazdi, Adilkhan Kapanov, Mostafa Kermani, Almaz Saukhimov, Arsalan Hekmati, Mehdi Bagheri IEEE Transactions on Industry Applications, 2025 This study analyzes an underwater inductive wireless power transfer (UIWPT) to be used in offshore vehicles. Fixating on inadvertent eddy current losses (ECLs), this study offers an approach to tackle this concern based on the optimal selection of main design parameters of Archimedean magnetic coils. An accurate analytical electromagnetic field model is derived for directly calculating ECLs, and based on the ECL model, the main design parameters of coils are selected. The electrical fundamental components of coils are calculated as a function of the selected design parameters. A numerical metaheuristic optimization method along with the formulation of a multi-objective function and inequality constraints is utilized to estimate the selected parameters of coils. This function addresses various design objectives simultaneously, considering the water medium and inequality constraints. For optimization purposes, an electrical equivalent circuit model is derived, considering the ECLs impact by reflecting these losses in the equivalent circuit model. The ECL model is verified through Finite Element Analysis (FEA). Finally, a laboratory scale setup is developed and UIWPT experiments are conducted to validate the equivalent circuit and analytical modeling, the calculation of components, and the simulation study.
Enhanced Domino Wireless Power Transfer for Transmission Line Monitoring: Overcoming External Metal Object Interference and Optimizing Coil Design S.S.H. Yazdi, S. Shafiei, A. Kapanov, Y. Shakhin, A. Namadmalan, M. Bagheri IEEE Transactions on Power Delivery, 2024 Utilizing domino resonant inductive power transfer (DR-IPT) system embedded in disk insulators to energize monitoring systems for transmission lines has been recommended in this century. However, presenting the external metallic objects (EMOs) in the volume encompassing the involved coils will affect the electromagnetic field and induce eddy currents. This research has specifically focused on and provides a new solution to overcome this issue. The solution proposes a new electrical circuit design, modeling, and analysis, and employs numerical metaheuristic optimization techniques to tackle the issue, and verifies the entire approach experimentally over a 63 kV transmission line model. New electrical circuit parameters (ECPs) in the presence of EMOs are obtained, and analytical equations for air-core Archemidean magnetic coils' ECP calculation are provided and experimentally verified. Moreover, a comprehensive independent design parameter (IDP) specification method is proposed, and a multi-objective function is defined to meet design objectives simultaneously in the presence of EMOs taking into account the inequality constraints. The system-level impacts of the EMOs on the transfer performance of the DR-IPT are also discussed, analyzed, and optimized, and the (system-level) accuracy of the proposed design method is discussed and experimentally verified.
Impact Analysis of Sea Environment on Capacitive Power Transfer Systems: Equivalent Circuit Parameters and Performance Analysis Adilkhan Kapanov, Seyed Saeid Heidari Yazdi, Sadjad Shafiei, Askat Kural, Mehdi Bagheri 13th International Conference on Renewable Energy Research and Applications Icrera 2024, 2024 It is suggested that capacitive power transfer (CPT) technologies can be used to recharge electric maritime vehicles' batteries. This work presents a configuration of the Underwater Unmanned Vehicle (UUV)-CPT system. The modelling of the systems' equivalent electrical circuit is discussed and the theoretical analysis of the External Watery Medium (EWM) on the Equivalent Circuit Parameters (ECPs) is conducted. To observe the effects of the EWM over the system, 3-D Finite Element Analysis (FEA) is performed on both cases with and without EWM. Using the Particle Optimization Algorithm (PSO), the calculations for the new ECPs of circular electric couplers are specified and the implications of EWM are carried out. The accuracy of the proposed parameter specification approach is examined and verified through experimental setup. The system-level impacts of EWM on the performance of the capacitive power transfer system are analyzed.
Analyzing Sea Environment's Effects on Inductive Power Transfer Systems: Equivalent Circuit Parameters and Performance Analysis Seyed Saeid Heidari Yazdi, Sadjad Shafiei, Adilkhan Kapanov, Mostafa Kermani, Amin Hajizadeh, Mehdi Bagheri Proceedings 24th Eeeic International Conference on Environment and Electrical Engineering and 8th I and Cps Industrial and Commercial Power Systems Europe Eeeic I and Cps Europe 2024, 2024 In this paper, the component-level and systemlevel influences of sea environments on the inductive power transfer (IPT) system are investigated. Archimedean coils are placed on the seabed and under the underwater unmanned vehicle (UUV) to recharge UUV's battery during its marine life monitoring mission and prolong its mission duration. However, seawater, characterized by its conductivity and relative permeability, acts as an external medium for the IPT system and influences its equivalent circuit parameters (e.g. self and mutual inductances and resistances). To study these influences, finite element method (FEM) studies are performed, and the impacts of the watery external medium on the magnetic flux lines distributions are investigated. Also, the process of inducing eddy currents in the watery external medium is analyzed and illustrated. Besides, an analytic method is proposed to reflect the impacts of the external watery medium on the equivalent circuit parameters of the IPT system. A preliminary analysis is also performed to study the impacts of the watery medium on system-level performances of the IPT system (e.g. output power, efficiency). The obtained results from theoretical and FEM studies are cross-verified by performing experimental studies over a prototype IPT system.
A Wireless Charging System Based on a DR-IPT to Power a UAV from Distribution Poles Seyed Saeid Heidari Yazdi, Sadjad Shafiei, Adilkhan Kapanov, Yussuf Shakhin, Alireza Namadmalan, Amin Zollanvari, Mehdi Bagheri IEEE Transactions on Industry Applications, 2023 This study proposes a wireless charging system (WCS) based on a domino resonant inductive power transfer (DR-IPT) system and series compensators to charge the batteries of unmanned aerial vehicles (UAVs) from distribution poles. Based on numerical metaheuristic optimizations, a comprehensive independent design parameter (IDP) method is proposed for the DR-IPT system. Self and mutual inductances and resistances of the coils are specified analytically as a function of the IDPs. Then, the electric equivalent circuit of the system is derived and analyzed. A multiobjective function is defined to meet design objectives simultaneously (supply of the nominal charging power, maximum efficiency, minimum copper weight, and uniform voltage rating of capacitors). Inequality constraints are included to satisfy the zero voltage switching condition of the input inverter, the size restrictions, and the maximum current density of the coils. Several case studies are defined, examined, and analyzed to determine the impact level of the available IDPs (geometries, interval space, and natural resonant frequency of coils), multiobjective weight factors, battery specifications, and implementation of the constant-current charging regime over the performance of the system. The successful performance of the proposed UAV WCS and IDP design method has been technically discussed and experimentally shown. The impacts of the proposed WCS on the flight time and travel distance of the test UAV are experimentally discussed.
Modeling, Control, and Operation of an M-DAB DC-DC Converter for Interconnection of HVDC Grids Seyed Saeid Heidari Yazdi, Kumars Rouzbehi, Miguel Jiménez Carrizosa, Amir Heidary, Mehdi Bagheri IEEE Systems Journal, 2023 Future high-voltage direct-current (HVDC) networks based on voltage source converters (VSCs) will have different structures (asymmetric monopolar, bipolar, or symmetric monopolar), voltage levels, control, and protection schemes. Therefore, dc–dc converters are needed to interconnect those VSC-HVDC grids and several technical issues on their control and operational systems must be adequately addressed. A dc–dc converter based on a modular-dual active bridge (M-DAB) converter is suggested to reach a desirable interconnection of the HVDC grids and regulate power flow (PF) between them. A dynamic averaged model is proposed for the M-DAB converter and its stability is analyzed using the Lyapunov function. Moreover, a new local controller based on nonlinear control theory is proposed for the M-DAB. The new M-DAB local controller is integrated with the energy management system (EMS), by updating the PF equations, to create a complete control structure. Considering the CIGRE DCS3 HVDC test system and the studied M-DAB, static, dynamic simulation, and experimental studies are conducted and the dc–dc converter and the performance of the designed controllers and the EMS are examined and validated.
Power system stability improvement considering drive train oscillations of virtual synchronous generator-regulated type-4 wind turbines Seyed Saeied Heidari Yazdi, Yaser Shokri‐Kalandaragh, Mehdi Bagheri Iet Renewable Power Generation, 2023 Abstract The type‐4 wind turbine generators (WTGs) can provide inertial frequency response by implementing the virtual synchronous generator (VSG) concept. However, unstable torsional oscillations (TOs) would be induced in the multi‐mass‐spring drive‐train which can destabilize the entire power system. In this study, participation factor analyses are performed for a power system inclusive of a thermal unit and aggregated WTG system. The system's eigenvalues are characterized and the possible detrimental impacts of TOs on the inertia provision process and overall power system stability are demonstrated and the related stability limits are identified. A comprehensive active torsional oscillations damper (CA‐TOD) and a supercapacitor‐based energy storage system (ESS) are presented and discussed to implement the CA‐TOD. A state of charge (SoC) regulator is also employed to set the reference speed difference for the turbine‐generator. Small‐signal studies and electro‐magnetic transient (EMT) simulations are performed to evaluate the functionality of the CA‐TOD and SoC controller and estimate their impacts on the system's dynamics. The robust performance of the CA‐TOD is compared to the band‐pass filter‐based TOD by sweeping key control parameters of the VSG and emulating drive‐train parameter uncertainty. Key results are cross‐verified by EMT simulations of a multimachine power system.
