Recently, with growth in utilization of renewable resources engineers and researchers have been motivated to offer new methods for their application in distribution networks. In this regard, optimal sitting and sizing of renewable resources as two main parameters in designing distribution network can reduce loss, operation costs and voltage deviations. In this paper, a multi-objective evolution...

Utilization of energy storage system (ESS) in microgrids has turned to be necessary in recent years and now with the improvement of storage technologies, system operators are looking for an exact modeling and calculation for optimal sizing of ESS. In the proposed paper, optimal size of ESS is determined in a microgrid considering demand response program (DRP) and reliability criterion. Both lar...

We describe a fast (linear time) procedure to optimally size transistors in a chain of multi-input gates/stages. The fast sizing is used in a simultaneous sizing and restructuring optimization procedure, to accurately predict relative optimal performance of alternative circuit structures for a given total area. The idea extends the concept of optimally sizing a buffer chain[5], and uses taperin...

Microgrids (MGs) contain a diverse mix of energy resources to provide safe and secure power to the consumers. Batteries are utilized in MGs for further energy security assurance as well as cost minimization. In this paper, an efficient approach is introduced for simultaneous energy management and optimal battery sizing to accomplish economic MG operation. Also, demand response programs are empl...
