Power flow is used to load the power system and generation data. The output of the power flow includes the voltage and angle values of the different buses, including the calculation of the active power, inactive power and the constraint on each branch. The implementation of the power flow is by solving the equation to…

Cambodia is a country in Southeast Asia in the southern part of Indochina and have climate warm, humid and tropical. Based on the monsoon, Cambodia has two seasons the dry season and the rainy season. The dry season runs from November through April, when the dry wind blows from Siberia. The rainy season runs from…
A study on Design and simulation of a photovoltaic system for stand-alone and grid-connected operation mode for a residential in Cambodia. The purpose of the project study is to focus on the supply of energy, which is clean energy, reduce energy consumption that affects the environment, and the supply of electricity to a home sustainably,…
This thesis presents a robust control strategy for a single-phase DC-AC inverter with output LC-filter. The control method using dq-synchronous frame is commonly used for three-phase systems but it is quite challenging for single-phase systems. In this thesis, an all-pass filter is utilized to create an artificial β-signal so that the proposed controller can be…

Cambodia aims to supply electricity to all villages with 100% 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 in the past few years.…
A robust control strategy is proposed for a three-phase grid-connected inverter under unbalanced grid voltage conditions in this thesis. This scheme consists of dual-current controllers for positive and negative sequence components to achieve one of three control objectives: i) supplying balanced three-phase current, ii) supplying constant active power, and iii) supplying constant reactive power to…
Abstract The over-dependence on fossil fuels as primary energy source has led to myriads of problems such as global climatic change, environmental degradation and various human health problems. Moreover, the recent rise in oil and natural gas prices has called for researchers towards alternative energy sources for the future. This study therefore investigates the digestion…
Traditionally, in order to control output voltage of the Three-Phase Inverter, the proportional-integral (PI) controller using dual-loop voltage control strategy has been used. However, physical input constraints were not considered in the design of the PI controller, and there was no analytical method to determine the control gain. This paper presents a dual-loop inverter voltage…
