   A Novel UPQC Configuration with Integrated Battery Energy Storage and Solar PV
By Rajarshi BASU, Mahesh Kumar MISHRA [View]
[Download]

Abstract: The integration of power electronics in the current power system has presented various challenges,such as unbalance, harmonics, and voltage disturbances. To tackle these issues, this paper introduces a novel UPQC topology with integrated battery storage and solar PV using the 3-port converter. The 3-port converter being part of a reduced switch scheme, achieves the above objectives with only twelve power electronic switching devices. This work describes the operation of the proposed configuration alongwith detailed emphasis on its control aspects. This work also proposes a modified phase angle control algorithm to control the phase angle of the series injected voltage under various grid and load conditions, comparing different UPQC control strategies. The operation of the proposed configuration with the above features and objectives is validated in MATLAB Simulink.

   Discrete-Time Cascaded-Control Design of Photovoltaic Systems for GMPPT and Power Curtailment Operations
By Muhammad Saad SALEEM, Gyanendra Kumar SAH, Hans-Günter ECKEL [View]

Abstract: This paper presents an efficient method to scan the power characteristics of photovoltaic (PV) systems in a few milliseconds. Further, it proposes and analyses the discrete-time cascaded-control designs for the grid-connected PV systems for two different operations (Global MPPT (GMPPT) and power curtailment), ensuring efficient performance during rapidly changing or non-uniform environmental conditions. A simple strategy is also discussed to predict the maximum available PV plant power when the environmental conditions vary between two consecutive scanning events to guarantee stability during the power curtailment operations. The performance of the proposed controllers is validated, analyzed, and compared using MATLAB/SIMULINK. The power curtailment operation is found to be superior to the GMPPT operation, ensuring stable operations during three-phase failure conditions.

   Frequency regulation method of electrolytic hydrogen production load based on novel interfacing hybrid rectifier with self-adaptive control
By Xin MENG, Cheng LI, Shuhan ZHOU, Mingzhi HE [View]
[Download]

Abstract: The electrolytic hydrogen production based on renewable energy is a promising hydrogen production method, whereas the system lacks inertia and damping characteristic, and the power of renewable energy source fluctuates. In this paper, a novel interfacing hybrid rectifier topology of electrolytic hydrogen production load with self-adaptive control is proposed, and the multi scale frequency regulation method of electrolytic hydrogen production load is achieved. The simulation results are provided to verify the effectiveness of proposed method.
