The virtual inertia J in single-phase synchronverter (SPSV) can be designed specifically to improve system stability. However, J also relates to active power loop (APL) and reactive power loop (RPL) time constants, which restricts the flexibility of control parameters choice and increases the complexity of parameter design process. This paper proposes a method to increase SPSV overall inertia without...
Microgrids are poised to become a major worldwide development in light of the numerous benefits they offer. However, the control and management of such systems require keen attention, as stability issues in microgrids have proven to be an important topic of research. It is a point of emphasis, that microgrids operating as stand-alone systems are particularly unforgiving in the sense that the combined...
Many transmission entities around the world are considering the use of modern synchronous condensers as part of their overall transmission solution. This paper explores the performance characteristics of synchronous condensers and provides reasons why this time-proven technology is now again seen as offering many beneficial characteristics to the transmission grid. Of particular interest are applications...
The non-dispatchable energy output of PV generators has an adverse effect on the stability of microgrid especially capacity-limited microgrid with high PV penetration. To solve this problem, a unified power control strategy for PV generators is proposed to mimic the performance of synchronous generator (SG) in power system. As a supplementary supply, fuel cell is equipped in the PV generator to reduce...
