Load serving entities (LSE) of industrial district that have the operation responsibility of electric network, must procure the consumers electricity from wholesale electric market or the utility’s distributed generation (DG). The generation expansion planning (GEP) has a crucial impact on the optimality of LSE’s operation. In this paper, an innovative GEP is presented in which the location, ti...

Nowadays the combined power generation system has become one of the most promising solutions to address the power needs of different regions. Given the discontinuity of energy produced by renewable sources a proven practice of combining these renewable energies can be a good solution for generating electricity in different atmospheric conditions, and with an appropriate combination of these sou...

The reliability of distribution networks is inherently low due to their radial nature, consequently distribution companies (DisCos) usually seek to improve the system reliability indices with the minimum possible investment cost. This can be known as system-oriented reliability planning (SORP). However, there can exist some customers that are not satisfied by their reliability determined by ado...

In recent years, in Iran and other countries the power systems are going to move toward creating a competition structure for selling and buying electrical energy. These changes and the numerous advantages of DGs have made more incentives to use these kinds of generators than before. Therefore, it is necessary to study all aspects of DGs, such as size selection and optimal placement and impact o...

Recent increment in carbon emission due to the dependency on fossil fuels in power generation sector is a critical issue in the last decade. The motivation to Distributed Generation (DG) in order to catch low carbon networks is rising. This research seeks to experience DG existence in local energy servicing in microgrid structure. Optimal sizing and placement of DG units is followed by this pap...

After a permanent fault occurs if it is not possible to supply the load in the network, the optimal load restoration scheme allows the system to restoration the load with the lowest exit cost, the lowest load interruption, and in the shortest possible time. This article introduces a new design called Smart Load Shedding, abbreviated SLS. In the proposed SLS scheme, the types of devices in smart...

The ever-growing demand for higher accuracy in scientific simulations based on the discretization of equations given on physical domains is typically coupled with an increase in the number of mesh elements. Conventional mesh generation tools struggle to keep up with the increased workload, as they do not scale with the availability of, for example, multi-core CPUs. We present a parallel mesh ge...

در این تحقیق، روش های پیاده سازی فیلتر با پاسخ ضربه محدود (فیلتر fir) مورد بررسی قرار می گیرد. برای پیاده سازی فیلتر fir از دو واحد(mac) multiply accumulate و distributed arithmetic (da) استفاده می شود. پیاده سازی فیلتر fir با da از 50 تا 80 درصد مساحت اشغالی را بهبود می دهد؛ همچنین توان مصرفی را نیز کاهش می دهد. روش هایی برای بهبود ساختار اولیه ی da نیز ارائه می شود که باعث افزایش کارایی فیلتر...
