Australia has topped the world in the penetration of residential roof-top solar generation systems. These residential solar generation systems are connected to the Low Voltage (LV) supply network which is not designed for two-way flow of electricity. Localized voltage rises due to excess solar generation feeding energy back into the supply network is commonly experienced. Supply utilities do no...

This project deals with the application of distribution generation with energy storage system connected to the low– voltage microgrid by coupling inverter for simultaneous energy management and other aucillary services that include the compensation of power quality disturbances. To address inaccurate power sharing problems in autonomous islanding microgrid, an enhanced droop control method thro...

Penetration of equipment such as photovoltaic power generations (PV), heat pump water heaters (HP), and electric vehicles (EV) introduces voltage unbalance issues in distribution systems. Controlling PV energy storage system (ESS) outputs or coordinated EV charging are investigated for compensation. However, some exist, dependency on installed capacity fairness among consumers. Therefore, the i...

− The study presented in this paper aims to develop a new method for active and reactive power balancing in a four-wire stand-alone microgrid (MG), which feds single phase loads. Two unbalance compensation controllers are used, for active and reactive powers. The compensation is based on a dump load (DL) and a static compensator (STATCOM), which ensure the balance of the active and reactive pow...

The vibration originated from the rotor’s unbalance mass impacts on the current oscillation. When the rotor rotating at high speed, power amplifier circuit will be burned down by excessive vibration control current, and at the same time the excessive control force will be generated. The vibrating force transfers to frame, which causes the system vibration and influence the dynamic properties an...

This paper presents a review study for hybrid intelligent optimization for operating solar generators in electric distribution system. A number of optimization techniques have been proposed in the literature review to solve optimization for solar generators in electric distribution system to meet the operational controls such as voltage drops, transmission limits, and voltage unbalance limits. ...

The paper aims to assess sources of error in attempting to meet standards for the measurement and reporting of negative sequence voltage unbalance. This is of importance when making use of low performance instrumentation where three difficulties may arise: (i) rms voltages rather than the fundamental is used; (ii) the magnitude but not the phase of line-neutral voltages are available; and (iii)...
