Electrical Distribution Systems (EDS) are facing ever-increased complexity due, in part, to fast growing consumer demands and the integration of large amounts of distributed energy resources. The conventional operation modes need to be adapted to the significant changes. With advanced Information and Communication Technology (ICT) infrastructure and sophisticated new functionalities for energy management,...
Recently, there has been a considerable increase of distributed generators (DGs) connected to the distribution network. Therefore, the concept of the microgrid has been developed. A microgrid is a cluster of DGs, loads and power storage devices that is typically connected to the distribution network via a single point of connection. Most DGs are connected to the microgrid via a power-electronic inverter...
For a coordinated integration of the increasing amount of distributed generators in the distribution network, the microgrid has been presented. For the islanded operating condition of the microgrid, the conventional approaches for grid control are no longer applicable as the microgrid characteristics differ significantly from those of conventional power systems. Therefore, in this paper, the reactive...
This paper describes the operation of a microgrid that contains a custom power park (CPP). The park may contain an unbalanced and/or nonlinear load and the microgrid may contain many distributed generators (DGs). One of the DGs in the microgrid is used as a compensator to achieve load compensation. A new method is proposed for current reference generation for load compensation, which takes into account...
With the rapid development and promotion of distributed generation technology, microturbine generation system (MTGS) appears extremely superior both in commercial and scientific aspects. According to the ??controllable load?? exterior characters for distributed generators under the parallel operation of microgrid, a complete mathematical model, regarding a high speed and single shaft microturbine...
This paper describes control methods for proper load sharing between parallel converters connected to microgrid supplied by distributed generators. The model of the microgrid power system is simulated in PSCAD. It is assumed that the microgrid supplies a load both in grid connected and islanded modes. Both passive loads and inertial loads are considered. A control strategy is proposed to improve the...
