Power photovoltaic system grid MV EDC 22 kV AT Mesang District Prey Veng Province, the purpose of the research is to find methods and procedures that are highly effective on the system grid connected with national transmission line 22kv That we can produce more energy to supply completely in Mesang and other nearby districts. Obviously,…

Three-phase inverter have drawn a lot of attention from researchers due to its widespread in industrial and renewable energy integration. This thesis presents a deadbeat control strategy for three-phase inverter with LC-filtered output. The DC input of this proposed inverter is 650VDC with output 220VAC. The control law of this method utilizes state feedback with…

This thesis presents a robust control technique for three-phase LC-filtered inverter under unbalanced load conditions. Under unbalanced load cases, the output voltage becomes unbalanced due to the presence of negative sequence voltage. To obtain a well-balanced three-phase voltage, the negative sequence must be eliminated. Therefore, a paralleled voltage control is proposed in this paper for…

Lightning protection system in high voltage substation (230kV) using Shielding Wire and Lightning Spike.The purpose of this research was to find out the most effective methods and procedures to be used in the project study of the lightning protection system in the substation with high voltage (115kV and 230kV) in which we built this lightning…

The ever-increasing demand for the electric power has caused speeding up expansion of power systems to be able to fulfil costumers’ needs for reliable, cheap, and high quality electric power. Active power losses reduction in transmission system is known as an important respect which is raising among popularity of specialists and usually it is very…

This research aims to use the mirror reflection on the Solar PV Standalone system; which called called PV Mirror Integrated Solar PV System. (MISPVS),in order to study details about whether it can be provided a get better output than using conventional solar panels called Traditional Solar PV System (TSPVS). In order to get good and…

This thesis presents the Power Loss Analysis on Bidirectional 48Vdc 12Vdc Converter of Electric Vehicles with High Frequency Controller (100kHz). In making this device, it is perfect for the applications because the device is designed to increase and decrease the voltage using a single controller. It is suitable for which application is narrow space. On…

The paper presents a study on the optimization of electric vehicle Charging Demand Using Synchronized Photovoltaic and Grid 230V Sources. The first part is focused on the optimization of the EV charging demand. Firstly, a brief introduction with daily travel behavior which focuses on the context of how people use their vehicle is described. Then,…

Power inverters now act as an important emergency power transmitter in the event of a large power distribution failure. The AC output voltage of a power inverter is generally not sine and as a result has too much harmonic content. The sine pulse width modulation scheme (SPWM) is typically used to convert a DC power…

The Government of Cambodia has set a goal to supply 100% of all villages with electricity by 2020. In fact, in 2015, the supply was 62%. Electricity consumption in Cambodia is growing at an average annual rate of 6.9%. Seeing the shortage of energy in the future, many PV Power Plant projects have been installed…
