One of the main problems in wind energy conversion system (WECS) is how to achieve maxim­u­m output power in different wind speeds. Maximum methods for maximum power point tracking in wind energy conversion syst­e­ms require the knowledge of system characteristics and mechanic sensors. So, using these methods practically will follow with high price and an abundant difficulties. In this pape...

This study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. Wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. However due to unpredictable nature...

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...

FACTS technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is oneof the most important FACTS devices used in the parallel compensation, enhancing transient stability andetc. Since three phase fault is widespread in power systems, in this paper STATCOM is used...

In power systems, a connected topology is created to increase reliability and economic performance. Increasing dimensions of power systems on the one hand and the need to continuously monitor power systems for secure operation on the other challenge the evaluation of power system security. In such conditions, due to economic conditions and considering the fast growth of consumers in a power sys...

نوسان توان پدیده پیچیده ای است به طوریکه از دهه 1940 و شاید پیش از این سالها موضوع تحقیقات مختلفی بوده است. تحقیقاتی که در زمینه پدیده نوسان توان انجام شده اند بیشتر به آشکارسازی این پدیده و اثر آن بر عملکرد رله های حفاظتی پرداخته اند در حالیکه تحلیل صرف انی پدیده کمتر مورد توجه قرار گرفته است. اما نویسنده بر این باور است که برای کشف روشهای جدید آشکارسازی نوسان توان، بررسی این پدیده به روش تحلی...
