This paper presents technical feasibility study of a hybrid energy system, including renewable and non-renewable resources and […]
In this paper, a comprehensive algorithm using modified invasive weed optimization is introduced for allocating distribution generation (DG) sources along with considering demand response (DR). Three aspects such as technical, economic and environmental are taken to account to define the optimized size and location for DG or DR. In addition, a new voltage fitness function […]
In this paper, neuronal direct power control (DPC) strategy is applied for a doubly fed induction generator (DFIG) based wind energy generation system. Used in three level neutral point clamped (NPC) rectifiers, to directly control of the active and reactive power, switching vectors for rotor side converter were selected from the optimal switching table using […]
In this paper, new reactive power market structure is studied and presented. Active power flow by itself causes active and reactive losses. Considering reactive losses of active power flow in the reactive power market without paying any costs is the main purpose of this paper. For this purpose, new methodology for reactive power market structure […]
due to the importance of providing reliable electricity for consumers in today’s power networks, the need for studies in the field of power systems reliability is feeling increasingly considering inherent uncertainties of renewable sources. Therefore, the main challenge of this study is to provide an efficient technique for evaluating reliability of power systems considering economic […]
In recent years, renewable energy technologies such as wind and solar have had significant growth and they can be used close to the consumption centers in order to remove high-voltage transmission lines. Using these sources with a power storage in the form of a hybrid system provides the increase of system reliability. The importance of […]
In this paper, the direct torque control torque based on space vector modulation (DTC-SVM) for permanent magnet synchronous generator connected to the variable-speed wind power generation system will be discussed. One of the most widely used in industry to convert voltage converters, converters back to back due to the very good features it is used. […]
The development and installation of Distributed Generators (DGs) in distribution power networks turned these networks from a passive into active ones in power systems. Proper management and control of these resources can help to improve power quality, and increase security and effectiveness of power networks. The power management of DGs considering their operating cost along […]
During the extremely-hot weather or transient heat waves, air conditioners are the main contributors to highest peak electricity demand which may lead to the widespread blackouts or brownouts. Meanwhile, electric drive vehicles are rapidly gaining popularity due to the global warming and energy crisis. Hence, this paper schedules on optimal charge and discharge decisions of […]
In this paper we presented a novel MEMS acoustic sensor using corrugated diaphragm. The corrugated diaphragm is used to decrease the effect of residual stress and thus improve the sensitivity of micromachined acoustic sensor. The displacement and mechanical sensitivity of flat and corrugated diaphragms, and also open-circuit sensitivity and pull-in voltage of sensors are calculated […]
