![]() | A Novel Hybrid Energy Storage Topology and its Control Algorithm
By Fengqi CHANG, Zedong ZHENG, Yongdong LI | |
Abstract: A novel hybrid power storage topology based on modular multi-level converter (MMC) is proposed in this paper. The topology is highly modularized and embedded voltage equalization for power storage cells is realized. The hybrid power storage system based on proposed topology was built using super capacitors and batteries. Corresponding power dividing strategy is proposed to improve working conditions of batteries and to extend their lifetime. Experiments are implemented to verify the performance of the proposed topology and the control algorithm.

![]() | Compact Energy Source for Emergency Engine Staring based Synergetic Battery-Ultracapacitor Circuit
By Moshe AVERBUKH, Alon KUPERMAN, Lineykin SIMON | |
Abstract: The present article presents an original, compact and powerful electric source, synergistically combining ESB and UC for emergency starting of internal combustion engines. The prototype of this device was created on the basis of an original circuit solution; also, a special algorithm for optimal charging of the UC was developed. The prototype was successfully tested with a diesel engine.

![]() | Fault-Tolerant Operation of the Modular Multilevel Converter in an Energy Storage System Based on Split Batteries
By Andre HILLERS, Jürgen BIELA | |
Abstract: This paper proposes a new control structure to operate a split-battery energy storage system (sBESS) based on the modular multilevel converter (MMC) in case of multiple module faults. Energy can be shifted independently between the arms to achieve an equal power draw from all batteries and an equalization of their state-of-charge, even in case of fault. Because this operating mode requires the converter to drive additional balancing currents through its arms, this has an influence on the design, which is discussed in detail. Comprehensive simulation results demonstrate the effectiveness of the proposed approach and confirm the design considerations.

![]() | Simulation and investigation of a kinetic energy storage as part of EPS
By Aleksey VORONTSOV, Mikhail PRONIN, Maksim KUZIN | |
Abstract: Opportunities of building a kinetic energy storage based on an asynchronized hydrogenerator with- out a flywheel with a dual frequency converter in a rotor circuit have been discussed. Control algorithms have been proposed. The storage and other devices have been simulated by a methodology of computing systems by interconnected subsystems, which enabled minimization of machine time consumption for computations. Operation conditions of the accumulator in starting conditions, and also during operation as part of an electric power system, have been analyzed on the models.
