Those two quantities, voltage and current, depend on some manufacturing and environmental parameters such as the temperature and the incident irradiance. Accordingly, this paper shows the impact of such parameters on the electric behavior of PV cells/Modules. An electronic circuit, made up of a photocurrent source, a junction diode, a series and a shunt resistances represent the PV cell considered within this paper. Within this paper, a Matlab/Simulink model of a PV cell/module is presented. To validate the Matlab/Simulink model of the PV cell/module, real data of the AEGAS-P605-250 PV module is implemented in PVsyst. 6.6.3 tool to highlight the effect of manufacturing and climate parameters on the electric behavior of the module.</p> Tarek Selmi Hedi Dhouibi Jalel Ghabi Copyright (c) 2019 Tarek Selmi, Hedi Dhouibi, Jalel Ghabi http://creativecommons.org/licenses/by/4.0 2019-11-02 2019-11-02 4 11 11 16 10.24018/ejers.2019.4.11.1607 Power System Market Planning https://ejers.org/index.php/ejers/article/view/1602 <p>The loss of load expectation (LOLE) considered an acceptable security standard across most of the national electricity systems. In the present study, the LOLE is calculated. This means that the LOLE needs developing a model. The developed model serving to assesses the security of supply risks associated with the different electricity capacity margin levels, where the capacity margin is the level by which available electricity generation capacity exceeds the maximum expected level of demand. Then, the developed model updated on an annual basis. The annual update is helping to fulfill the Electricity Authority for planning, operation and control. The developed model will assess the system by calculating the capacity margin probability by combining both the generation and load models. The calculation of LOLE is an internationally accepted criterion in capacity adequacy.&nbsp; The results for the model of each region vary due to several factors, such as generation resource, load forecast, and forced outage rates (FOR). The estimation of the risk is economically optimal reserve margin to a number of case studies assumptions considered in the present study. The results help in future planning for the electric system operation and control. Furthermore, the study is helping to evaluate the implications of the obtained results for the electricity policy market to determine the best model for market design in the future.</p> Isa Salman Qamber Mohamed Y Al-Hamad Copyright (c) 2019 Isa Salman Qamber, Mohamed Y Al-Hamad http://creativecommons.org/licenses/by/4.0 2019-11-06 2019-11-06 4 11 17 21 10.24018/ejers.2019.4.11.1602 Study on Implementation of Rooftop Photovoltaic Power Plant as an Effort to Attain a Sustainable Campus https://ejers.org/index.php/ejers/article/view/1606 <p class="Abstract"><span style="color: black;">The concept of Green Campus means that the University has implemented environmental preservation activities, energy efficiency, and deliver comfortable conditions to support learning and work activities. The activity to harvest renewable energy is one of several approaches towards a sustainable campus. This study aims to analyze the technical and economic feasibility of a solar power plant erected on the roof of buildings within the campus area. Based on the University of Samudra development master plan, it has carried a technical and financial feasibility study with the assists of the System Advisor Model (SAM) software. The analysis shows that the current roof area is possible to generate electrical power of 3 MW, with economic calculations of electricity production costs of 11.7 cents/kWh.</span></p> Razali Thiab Munira Amudy T.

The robot have 6 degrees of freedom, with a cutter attaching to the end of the end-effector. The workpiece is fixed on the clamping table. Using robot in form-shaping machining parts enables increasing the flexibility of selecting machining observation area, increasing capability of selecting engineering manipulation, increasing quality and machining efficiency. In machining process, because of the cutter moving along the machining trajectory in multidimensional space, computing and planning trajectory is more complex. In order to planning the trajectory, it need to derive the kinematic equations of the robot, and deal with the kinematic problems. The kinematics problems are solved with the constraints that the position, orientation, velocity of the tool frame must be coincided with the ones of the workpiece frame. After computing, the results are validated by simulation of robot motion.</p> Ha Thanh Hai Copyright (c) 2019 Ha Thanh Hai http://creativecommons.org/licenses/by/4.0 2019-11-08 2019-11-08 4 11 26 31 10.24018/ejers.2019.4.11.1619 Voice activated Home System for the Movement Impaired Aged Persons https://ejers.org/index.php/ejers/article/view/1616 <p>Smarthome system is one of the major growing industries that change the way people live, and most of these smarthome systems target abled young persons` seeking luxury and sophisticated smarthome platforms; but this design targets the disabled aged. This smarthome system allows the aged to wirelessly control home appliances from a centralized control unit. The developed system is integrated as a single portable unit that allows the user to wirelessly control lights, fans, electronic doors, electronic windows and robotic wheelchair. The system is portable and constructed in a way that it is easy to install, configure, run, and maintain. Here, voice being the primary interface between the aged user and the smarthome, a voice controlled smarthome system is designed, so that the users can perform their domestic tasks by just the use of their voices to speak their command words.</p> Godfrey Nwaji Okorafor Felix Kelechi Opara Nkwachukwu Chukwuchekwa Chigozie Gordon Ononiwu Copyright (c) 2019 Godfrey Nwaji Okorafor, Felix Kelechi Opara, Nkwachukwu Chukwuchekwa, Chigozie Gordon Ononiwu http://creativecommons.org/licenses/by/4.0 2019-11-17 2019-11-17 4 11 32 37 10.24018/ejers.2019.4.11.1616 Thermal Properties of Beef Tallow/Coconut Oil Bio PCM Using T-History Method for Wall Building Applications https://ejers.org/index.php/ejers/article/view/1627 <p>Thermal energy storage using Phase Change Materials (PCM) is now widely applied to wall buildings. In general, PCM which is used for applications on building walls is organic PCM and has temperature range from 0℃ to 65oC. Beef tallow and coconut oil is a type of organic PCM known as Bio PCM needs to characterize by using the T-History Method. The T-History method is more accurate than Differential Scanning Calorimetry (DSC) and Differential Thermal Analysis (DTA). This study aimed to determine the thermal properties of beef tallow/coconut oil PCM using the T-History method. The beef tallow and coconut oil as bio PCM material was used in this study with the variation are respectively: 100%, 70+30%, 60+40%, and 50+50%. Tests are carried out using the T-History method. From the results of testing and analysis obtained supercooling temperature, melting temperature, specific heat, and latent heat for bio PCM beef tallow/coconut oil.&nbsp;The effect of adding coconut oil mixture to beef tallow caused a decrease in melting temperature and supercooling temperature, while the specific heat and latent heat of bio PCM of beef tallow/coconut oil ranged from 2.96-2.19 kJ/kg.℃ and 101.05-72.32 kJ/kg.&nbsp;The result obtained that this bio PCM material of cow beef tallow/coconut oil can apply, as additional material in wall building applications.</p> <p>&nbsp;</p> Razali Thiab Muhammad Amin Hamdani Umar Copyright (c) 2019 Razali Thiab, Muhammad Amin, Hamdani Umar http://creativecommons.org/licenses/by/4.0 2019-11-19 2019-11-19 4 11 38 40 10.24018/ejers.2019.4.11.1627
