Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This paper presents, a Particle Swarm-Optimization (PSO) using Teaching Learning-Based Optimization (TLBO), and Antlion Optimization (ALO), for tuning PI controllers of the voltage regulator and current regulator for the control circuit of Static Synchronous Compensator (STATCOM). The type of STATCOM used is a 48-pulse Neutral Point Clamped (NPC) gate-turn-off thyristor (GTO)-based Voltage Source Converters (VSC). STATCOM is compensating power of up to ±10 MVAR. STATCOM control is provided based on a decoupled current strategy (d-q) using the current direct and quadrature components. Also, STATCOM fed on the dc-link side on the VSC by the renewable energy photovoltaic cells (PV) and battery, to provide the power of compensation. The strategy of enhancing power quality in the face of system fluctuations using STATCOM with multi-supply sources Photo-voltaic cells (PV) and the battery system on the capacitor channel of VSC converters, to provide the required power of compensation. The dc to dc boost converter has been used to regulator the power of PV cells, and the dc-dc buck-boost converter circuit has been used to regulator the power of battery energy storage. Happenings of energy quality during network perturbation or disturbance, like feeder, tripping and reclosing, and load switching were analyzed with the participation of STATCOM, so the multi-source (PV and battery) system with STATCOM suppresses these problems. A modified IEEE 12 bus test feeder with STATCOM has been used for the case study. The design and analysis have been carried out using m-file and SIMULINK for MATLAB 2015b
The present research is concerned with studying experimentally the characteristics of flow over six different models of humps which are manufactured with a suitable scale and fitted to a laboratory flume. The hump models are placed at 70cm and 130cm from the upstream (us) of the flume inlet. Dimensional analysis is carried out to identify the parameters affecting the experimental work. The results showed that models 2, 3, and 6 retain water and the damming phenomenon is occurred at distance 70 cm and 130 cm from the upstream (u/s) of the flume; but models 5 is able to activated these actions at the distance of 130 cm only; while models 2 and 4 are unable. The results are also showed that Froude Number (Fr) indicates that the type of flow at the upstream (u/s) of the hump is subcritical and is supercritical in the downstream (d/s), while it also find that the flow is supercritical at the hump in the case of damming occurrence. The results showed that there is a difference in the height of the water between upstream and downstream of the flume by 200% to 350% at distance 70 cm while it is found that this difference by 172.72% to 337.5% at distance 130 cm
