This paper proposes a novel strategy of control of the active power flow from the power system grid to a micro grid by a power electronic transformer (PET), consisting of controllable loads and distributed energy resources (DER), both renewable and non-renewable. A 60 Hz, step down transformer is generally used at the Point of common coupling (PCC) of a micro grid to connect to the power system grid...
Power system islanding can improve the continuity of power supply. Synchronous islanded operation enables the islanded system to remain in phase with the main power system while not electrically connected, so avoiding out-of-synchronism re-closure. Specific consideration is required for the multiple-set scenario. In this paper a suitable island management system is proposed, with the emphasis being...
The continuity of power supply can be improved by power system islanding. A possible solution, synchronous islanded operation, enables the islanded system to remain in phase with the main power system while not electrically connected, and so avoids out-of-synchronism re-closure. Specific consideration is required for the multiple-set scenario, and is the topic of this paper. A suitable island management...
Electricity demand has been rapidly increasing globally. More power plants and transmission lines are built to satisfy the customer demand. However, as distributed generation (DG) costs are less than the combined cost of power plant and expansion of the distribution and transmission systems. DG technologies are becoming potential contributors of electricity supplied by electric utilities. To meet...
