The Effect of Static Var Compensator Modelling in Evaluation of Power Systems Reliability

Adequate storage of reactive power is one of the most important requirements for the proper functioning of the power system in natural and critical conditions. The design and application of reactive power equipment play a very important role in maintaining the optimal performance and reliability of power systems. With the increasing use of static compensators in energy systems, the study of their effect on system performance indicators has become very important. In this paper, the role of different components of a static compensator (SVC) is investigated and the creation of an evaluation model to evaluate the performance of SVC will be mentioned. Then, by using appropriate indicators due to lack of active and reactive power such as unreliable expected energy supply (EENS), expected unmet supply (EVNS) and active load cut-off (ELC) are defined and the effect of SVC on The reliability assessment of the power system has been investigated.The results of this study are used for the management of SVCs as one of the important components of reactive power storage resources as well as more accurate design of power systems and control systems made by SVCs.
