In this research a vertical-axis wind turbine (VAWT-Darrieus type) is designed and optimized using QBlade software based on three design parameters. Three types of airfoils have been chosen to find out the suitable design to make three-bladed Darrieus type VAWT. A Savonius type VAWT was developed practically to characterize the developed generator coupling arrangement. This Darrieus type was simulated and optimized using Qblade. A practical test was done to compare the electrical and mechanical power, thrust of both turbines using a wind tunnel. After simulation, it was found that the Darrieus type VAWT with 1 meter height, 0.75-meter radius and 0.075-meter chord length with 75o circular angle made by “DU 06-W-200” airfoil has better coefficient of performance. On the other hand, the Savonius type VAWT having 0.37 meter and a radius of 0.11 meter showed 0.0006 Watt electrical power and 5.8844 Watt mechanical power at 4 m/s. Savonius type wind turbine with 0.37 meter height and 0.11 meter radius is applicable for low speed whereas larger 1 meter Darrieus type could be the proper choice.
Primary frequency control of large-scale PV-connected multi-machine power system using battery energy storage system
(International Journal of Power Electronics and Drive System(IJPEDS), Institute of Advanced Engineering and Science (IAES), 2021-09-30) Rahman, S. M. Imrat; Hazari, Md. Rifat; Hani, Sumaiya Umme; Pathik, Bishwajit Banik; Mannan, Mohammad Abdul; Mahfuz, Asif; Alam, Mohammad Khurshed; Hassan, Md. Kamrul
Large-scale grid-tied photovoltaic (PV) station are increasing rapidly. However, this large penetration of PV system creates frequency fluctuation in the grid due to the intermittency of solar irradiance. Therefore, in this paper, a robust droop control mechanism of the battery energy storage system (BESS) is developed in order to damp the frequency fluctuation of the multi-machine grid system due to variable active power injected from the PV panel. The proposed droop control strategy incorporates frequency error signal and dead-band for effective minimization of frequency fluctuation. The BESS system is used to consume/inject an effective amount of active power based upon the frequency oscillation of the grid system. The simulation analysis is carried out using PSCAD/EMTDC software to prove the effectiveness of the proposed droop control-based BESS system. The simulation result implies that the proposed scheme can efficiently curtail the frequency oscillation.

Software test estimation tool: comparable with COCOMOII model
(© 2016 IEEE, 2016-12) Islam, Shaiful; Pathik, Bishwajit Banik; Khan, Manzur H.; Habib, Md Mamun
This study illustrates an estimation tool for software test that provides the estimated time and the cost of any sort of software test project. There are different well-recognized estimation tools for software development process [9], however, there remains a lack of standard tools for estimation of Software Test phase. Therefore, the authors developed a web base tool (www.4beats.net/tpet/) in order to determine the time and cost of projects. This paper highlights the comparable result with COCOMOII (Constructive Cost Model) model. More than 22 projects are already estimated by this open tool and from them 5 case projects, namely, Climate Resilient Ecosystems and Livelihood (CREL), Management Accounts Consolidation System for Line Director (LDMACS), PBI (Police Bureau of Investigations) Works Management System Software, PBI Mobile Apps and Human Resources Management System (HRMS) have selected. This paper would play a vital role to estimate time and cost for software test project and be beneficial for the software industry.
