This paper proposes three phase grid connected anti-islanding controller based on distributed generation interconnection. This method is a combination of two detection methods namely active and passive. Firstly, Active islanding detection generates disturbances at the output of the distributed generation by use of Positive feedback and Continuous feedback signal injection which is based on DQ implementation...
This paper presents a grid connected system. Three phase DC-AC inverters used to convert the regulated DC power to AC power suitable for grid connection. Third harmonic injection PWM (THIPWM) was employed to reduce the total harmonic distortion and for maximum use of the voltage source. DSP was used to generate the accurate THIPWM for grid connection, by synchronizing the inverter voltage with the...
This paper presents the complete design of a photovoltaic installation that may be either used for internal electric consumption or for sale using the renewable energy incentive program by the state of Malaysia (SURIA 1000 and so on.). Moreover in this article an economic and environmental study is carried out on PV solar energy installations connected to the Malaysian electrical grid system. The...
Detailed analysis, simulation and hardware results of grid connected inverter with maximum power point tracker and power factor control in Malaysian climate are presented. A six-switch topology inverter with symmetrical Pulse Width Modulation (PWM) switching technique is used. A low pass filter is incorporated in the circuit to filter out unwanted harmonics and produce a sinusoidal AC current. Low...
The performance of maximum power point tracker in tropical climate has been presented in this paper. The maximum power point tracker output voltage and current are used for control purposes, rather than for its input voltage and current. It is shown that using the output parameters simplifies the maximum power point tracker controller. Moreover, using this approach, only one out of the two output...
