The HVDC technology can be represented by the combination of a Direct Current (DC) circuit with two power electronics converters, each one at a link terminal, for AC/DC and DC/AC conversion The principal characteristic of VSC-HVDC transmission is its ability to independently control the reactive and real power flow at each of the AC systems via the Point of Common Coupling (PCC). The active and reactive power is related to the power angle and the magnitude of  voltage in the reference -frame selected such that the quadrature component will result in the ratio between the maximum fundamental peak phase voltage and the DC total voltagehttp://dx.doi.org/10.4314/njt.v36i3.31

ABSTRACTWith the development of modern With the development of modern With the development of modern With the development of modern technology, technology, technology, technology, Smart Living is gradually changing people's life and thus providing a Smart Living is gradually changing people's life and thus providing a Smart Living is gradually changing people's life and thus providing a Smart Living is gradually changing people's life and thus providing a necessary technology to create convenience, intelligence and controllability. In this paper, a new necessary technology to create convenience, intelligence and controllability. In this paper, a new necessary technology to create convenience, intelligence and controllability. In this paper, a new necessary technology to create convenience, intelligence and controllability. In this paper, a new Smart Living Smart Living Smart Living Smart Living system is introduced for the Automatic Control of Heating and Cooling System in the Home. The system is designed system is introduced for the Automatic Control of Heating and Cooling System in the Home. The system is designed system is introduced for the Automatic Control of Heating and Cooling System in the Home. The system is designed system is introduced for the Automatic Control of Heating and Cooling System in the Home. The system is designed to assist and provide support in order to fulfill some of the needs of elderly and disabled in the home as the elderly to assist and provide support in order to fulfill some of the needs of elderly and disabled in the home as the elderly to assist and provide support in order to fulfill some of the needs of elderly and disabled in the home as the elderly to assist and provide support in order to fulfill some of the needs of elderly and disabled in the home as the elderly and the dis and the dis and the dis and the disabled are often in dire need of controlling their home environment.abled are often in dire need of controlling their home environment. abled are often in dire need of controlling their home environment. abled are often in dire need of controlling their home environment.
