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…
The energy market will become ever more important for Cambodia’s economy as it continues to develop, with rapidly increasing demand for electricity. The Cambodia Energy Outlook estimates an increase by 7.5times from 2015 to 2040. According to Cambodian authorities, electricity demand in the country is expected to grow from 1.5GW to 2.3GW by 2020, and…
The present study addresses for solving economic dispatch (ED) problems for power supply in the power system, which is an important role in the study of power system (Load Demand). The objective of Optimal (generation dispatch) Combination of power output to meet minimum cost (Fuel Cost Function equation) while satisfying the constraints. The Optimal (generation…
This thesis presents a robust control strategy of a three-phase off board bidirectional AC-DC battery charger for electric vehicle. The bidirectional charger also allows to use the full electric vehicle as an energy storage system for the electric grid, charging the in the peak-of times and delivering the energy back to the AC source in…
As the local and national clamor for foreign energy independent United States continues to grow unabated; renewable energy has been receiving increased focus and it’s widely believed that it’s not only the answer to ever increasing demand for energy in this country, but also the environmentally friendly means of meeting such demand. During the spring…
This thesis presents a robust control strategy of a three-phase off-board AC-DC battery charger for electric vehicle. Intelligent constant current-constant voltage (CC-CV) charger for fast charging a Lithium-ion battery. Increasing the charging current in the CC regime cannot guarantee the short charging time, so an optimal charging current exists in the CC-CV method. The proposed…
Direct current (DC) motor becomes a significant drive configuration for many applications across an honest vary of speeds. The convenience of control and excellent performance of the DC motor can make sure that the number of applications using them will continue for the predictable future. In this project, the speed of the DC motor is…
Energy wastage is one of the most frequently asked questions today, especially among technicians. Based on rising fuel prices and natural variations affecting GHGs emission caused by combustion of fossil fuels. At the same time, we see many way in which technology can capture the energy that is being thrown away. There is a device…
In a three phase AC power system active and reactive power flow from the generating station to the load through different networks, Bus and branches. The flow of active and reactive power is called power flow or load flow. It uses simplified notation such as one-line diagram and per-unit system and focuses on various forms…
