Recently, the renewable energy power generation has been widely used in residential customer by installing PV-rooftop on grid system. The PV-rooftop system uses inverter, which may generate the disturbance in the frequency range of 9-150 kHz due to its frequency switching. On the other hand, many household appliances also use inverter technology in their operation that may also generate the disturbance in the frequency range of 9-150 kHz even when it is connected to the clean supply provided by the utility grid. Since the power supplied by PV-rooftop system may contain disturbance, it is important to explore the effect of PV-rooftop system to the disturbance generated by household appliances. The study investigates the disturbance profile due to the interaction between the disturbance generated by PV-rooftop system and the disturbance generated by the household appliances. The devices under test are PV-Rooftop system as the power supply and the induction cooker, inverter-based microwave, vacuum cleaner, CFL and LED lamp as the household appliances. The results of the measurement show that the PV-rooftop generates disturbance at frequency 16 kHz when operated individually. The disturbance generated by PV-rooftop system is generally reduced when the household appliance is connected. The disturbance reduction has different trend. Some appliances including induction cooker and inverter-based microwave reduce the disturbance significantly due to their low internal impedance at the frequency of 16 kHz that may filter the disturbance of PV-rooftop system.

The performance of the bow thruster motor depends on the quality of the supplied voltage and the voltage coming out of the motor. Under unbalanced voltage situation, it will cause the poor performance of the motor. The latest regulation of International Convention for the Prevention of Pollution from Ships (MARPOL) requires that the ship's electrical system under the dynamic positioning operating mode, should be operated with a closed bus configuration. Under such configuration, motor thrusters is prone to the of electrical components failure such as harmonics. In this study, the investigation has been performed using MATLAB in order to see the effect of six voltage imbalance conditions occurring in the vessel on bow thruster motor performance with variation of voltage imbalance factor based on true definition of IEC. The resulted analysis has shown that there are various detrimental impacts resulted from different condition of imbalance of voltage. In the imbalance factor 5% condition undervoltage 3 phase has the smallest output power 22321.59 watt with the smallest torque 142.9039 Nm, but it has a power factor 0.762326 which is still allowed by rule of IEC.

It has been acknowledged that integration of DREG into electrical distribution system will increase the complication of the system load flow analysis. Therefore, development of reliable and efficient solution method to the DSLF problem is crucial so that the steady-state operation of distribution system, including the DREG, can properly be evaluated. In this paper, application of trust-region method in finding load flow solution of modern distribution network containing DREGs is investigated and presented. Trust-region method is a constrained optimization-based technique for solving a set of nonlinear equations. Trust-region method has successfully been applied in load flow analysis of conventional distribution systems (i.e. distribution systems without DGs). Unlike the forward/backward-based method, particular treatments such as branch/bus renumbering/ reordering are not needed in the trust-region method. These special treatments can be difficult to be carried out especially for large distribution networks. Moreover, since optimization method is used in the solution updating process, trust-region computation algorithm is quite robust. This feature is important in distribution system applications, particularly when the system is ill-conditioned. Validity of the proposed trust-region method is confirmed by the results obtained on three representative distribution networks, i.e. 12-bus, 33-bus networks, and 69-bus networks. In addition, the effect of DREGs installation on distribution system steady state performances is also investigated in this paper. Results of the investigation show that the system performances improve when the DREGs installed in the system.

This paper presents a low-frequency oscillation compensation in an electrical power system connecting large-scale electric vehicle loads (EVs). The particle swarm optimization (PSO) method has been adapted to adjust the control parameters of the generator under Power System Stabilizer (PSS) parameters. The EVs charging stations have been directly installed to the power grid for the battery charging process of the EVs according to the increasing number of EVs. The DC fast charging of the large scale EVs has been significantly affected by the low-frequency oscillation of the grids that have been considered in terms of power system stability margin. This paper has aimed to solve the methodology for turning the PSS parameters by adapting the PSO via MATLAB® and DIgSILENT®. The PSS could control the low-frequency oscillation in the proposed power grids. The simulation system has selected the 6-bus testing system, which has increased the EVs loads by 50, 100, 150, 200, and 300 percentages at bus No. B3. The simulation results have indicated that the rotor low-frequency oscillation could control instability region. Therefore, the proposed PSS controller turning could handle the power system swing and adjust the power system stability. In this condition, the proposed PSO method should have been explicitly used for low-frequency swing control of the generator's rotor into a balanced state under the large-scale EVs penetration level.
