An UPQC Based on Thyristor and Ultra Capacitor
Kongzhi Yu Xinxi Jishu, 2015 The traditional UPQC(unified power quality conditioner) cannot realize voltage compensation when the system’s power voltage deeply drops or interrupts in a short time. A new type of UPQC was proposed, which was added bidirectional thyristor, ultra energy

On the one loop $\gamma^{(*)}\to q\bar{q}$ impact factor and the exclusive diffractive cross sections for the production of two or three jets [PDF]
, 2016 We present the calculation of the impact factor for the $\gamma^{(*)}\to q\bar{q}$ transition with one loop accuracy in arbitrary kinematics. The calculation was done within Balitsky's high energy operator expansion. Together with our previous result for

IET Renewable Power Generation, Volume 18, Issue 15, Page 3268-3284, 16 November 2024.Integrate renewable energy system (RES) into grid‐connected load system in enhancing reliability and reducing losses. However, integrating these systems introduce power quality (PQ) issues, especially with non‐linear, critical, and imbalanced loads. Addressing this, a hybrid mantis search‐reptile search algorithm combined with a unified power quality ...
