| dc.description.abstract | Due to the increasing deployment of renewable energy resources, the proportion of conventional power plants is declining. As a result, reduction of frequency-regulation capability has become a significant challenge to be addressed. To mitigate this issue, battery energy storage systems are a favorable candidate owing to their fast response, high energy density, and diversity of battery chemistries. This thesis provides an improved adaptive state of charge-based droop control strategy for battery energy storage systems participating in primary frequency regulation in a large network. The proposed method has dual features including providing/absorbing power to/from the grid considering state-of-charge, and also enhancing short-term frequency response by giving an additional boost to the droop coefficient to reduce the maximum frequency dip/rise. It also allows batteries with a low state of charge to participate in frequency regulation without risking battery degradation or regulation failure. The performance of the proposed method is compared with three existing methods and comprehensive simulation studies are conducted to investigate the response of the grid-side and battery-side converter parameters while undergoing multiple contingencies. The proposed frequency regulation method has shown an improved frequency response in terms of maximum frequency dip/rise, compared with frequently utilized methods in the literature. From the grid’s viewpoint, the proposed method is beneficial as it fully utilizes the capacity of the battery energy storage system to support a weak grid with high penetration of renewable energy resources without exhausting the batteries. | en_US |
