SmartWAMS-The approaches for stability improvement in power system
نویسنده
چکیده
The main cause of wide-area disruptions in the present power network is due to the relatively long transmission lines between regions, the continuous load growth without a corresponding increase in transmission network capacities. This disturbances have stressed power systems further and forced them operate closer to voltage and angle instabilities. As a result, stability of such power systems becomes a serious issue in operation and control process. In recent years, the advance technology of Wide Area Measurement System (WAMS) provides observability of the status of the power system to operators in real time. In addition to, preplaned corrective actions of WAMS can be taken to minimize the risk of wide-area oscillation, increase the power transfer capability of the system and led to advanced application in wide area monitoring, protection, control system.

A Control Strategy for Flywheel Energy Storage System for Frequency Stability Improvement in Islanded Microgrid
The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...
