“…The voltage sags are also closely related to the low-voltage ride-through (LVRT) or fault ridethrough (FRT) studies in microgrids; hence relevant literature reports strategies that can be used to mitigate voltage sags [44][45][46][47][48], as well as LVRT strategies for microgrids [49][50][51]. Therefore, both voltage sag mitigation strategies and LVRT strategies are discussed here.…”

Ship microgrids have recently received increased attention, mainly due to the extensive use of power electronically interfaced loads and sources. Characteristics of these microgrids are similar to islanded terrestrial microgrids, except the presence of highly dynamic large loads, such as propulsion loads. The presence of such loads and sources with power-electronic converter interfaces lead to severe power quality issues in ship microgrids. Generally, these issues can be classified as voltage variations, frequency variations and waveform distortions which are commonly referred to as harmonic distortions. Amongst the solutions identified, energy storage is considered to be the most promising technology for mitigating voltage and/or frequency deviations. Passive filtering is the commonly used technology for reducing harmonic distortions, which requires bulky capacitors and inductors. Active filtering is emerging as an alternative, which could be realised even within the same interfacing converter of the energy storage system. The aim of this paper is to investigate recent developments in these areas and provide readers with a critical review on power quality issues, energy storage technologies and strategies that could be used to improve the power quality in ship microgrids. Moreover, a brief introduction to ship power system architectures is also presented in the paper.

“…Different harmonic, reactive, linear and nonlinear loads are connected to the derived common AC bus. The equivalent parameters are extracted in the simulations from the datasheet [11]. The developed MG containing PV-wind MG generating system is implemented in Simulink /MATLAB environment and is investigated for the real-time data measured at Birla Institute of Technology and Science, Hyderabad campus.…”

The number of DG systems like Photovoltaic and Wind Energy Systems are now penetrating more into the conventional power system. In microgrids, loads and generators are in the close vicinity. However, due to the unpredictable nature of non-conventional energy resources like wind and solar with varying loads, it is almost impossible to maintain an accurate power balance between the source and load. Furthermore, to compensate reactive power and harmonics of this AC microgrid and also to maintain a reasonable power quality, it is essential to use a state-of-the-art controller like shunt active power filter (Sh. APF). This research work is an effort in the same direction wherein the actual environmental data like solar irradiation and wind profile have been collected with the help of the weather monitoring system in BITS-Pilani Hyderabad Campus and this data has been used in conceiving and designing an AC microgrid of suitable capacity. The loads included in this system are both harmonic and reactive in nature. Finally, a Sh. APF with an appropriate control scheme has been incorporated in the proposed AC microgrid so that impeccable power quality is maintained at the load end, apart from achieving a good power balance.

A Sudden loss of a generating station and a sudden switching of heavy loads in the system are the major challenges for a power engineer. Coordinated scheduling of power is necessary to maintain the system parameters under control. In this paper a two-area power system is simulated for contingencies and the frequency deviation is controlled. The load flow studies are also conducted to study the behavior of the system. The results show that the variation of the frequency is within the allowable standards while the system is stable during the period.
