Using Abaqus software offer several advantages, one of which is high tensile strength. of course, tensile strength reflects the maximum amount of stress or tension the bolted joint can sustain at any given time without breaking. Joint member stiffness in a bolted connection directly influences the safety of a design in regard to both static…
In the standalone operation mode of the microgrid, the system is significantly weakened due to a lack of inertia support from the conventional synchronous generator. Hence, investigation of the impact of photovoltaic (PV) power variation and load transition on the standalone microgrid system both stability and quality are essential. In this paper, a microgrid system…
Anaerobic digestion is a technology that produce biogas from biomass. This paper presents a review on the biogas production from different substrate with co-digestion such as food waste, cow dung, food waste with cow dung, wetland grass with cow dung, food waste with cow and pig dung, and food waste with chicken dung. Operating parameters…
According to research in 2021, power generation in Cambodia is divided into 5 categories: 1- Hydropower plant with a capacity of 1329.70 MW equal to 43.51% 2- Diesel plant with a capacity of 643.95 MW equal to 21.07% 3- Power plant has 675.00 MW of coal power equal to 22.09% 4- Firewood and other biomass…
A big part of electrical energy consumption was used to generate hot water for uses in residences hotels and hospital. This current study introduced a method of using flat plate solar collectors to generate hot water so that the electrical energy consumption could be saved, and the annual cost of electricity could also be reduced.…
Use of phase change material (PCM) in water storage tank to generate tempera-ture stratification that could enhance performance of photovoltaic thermal (PVT) module was investigated by numerical simulation. A commercial PCM, filled in a set of 40 mm diameter spherical capsules contained in a 200-liter water storage tank was used and the storage was integrated…
In control of dynamical system, too high uncertainty of system parameters may cause fault of controller design which leads to instability. To avoid such undesired case, identification of good ap-proximation of dynamical model and its parameters is very important. In this paper, we propose methods for obtaining accurate value of each parameter for Unmanned Aerial…
The number of traffic accidents and theft of vehicles which are increasing every day around the world, has become the problem for people nowadays. Traffic accidents in remote areas cause difficulty for asking emergency help for the victim moreover, most vehicle owners worried about missing their vehicle and hopeless to find it back. This paper…
A linear matrix inequality (LMI)-based robust control is discussed in this paper for a three-phase grid-tied inverter with L-filtered output under unbalanced grid situation. The controller of this proposed method consists of two parallel current control for positive and negative sequence signals. Uncertainty models are also considered in this paper to provide wider range of…
A natural disaster is happening every year in the world. Countries like Japan, Indonesia, and the Philippines are often effected by unexpected climate change. Unexpected natural disasters destroy the landline, internet connection, and mobile communication systems infrastructure surrounding the disaster areas. In this research, the communication backup is proposed for Amateur grounding operators during unexpected…
