Abstract

Planning of the demand response has received special attention due to the cost of transmission lines development and shortage of energy resources beside the growth of demand. This research work is focused on the role of microgrid (MG) as an alternative solution for transmission system development and proposed a method for modeling of MGs in the capacity market. The results show that using of MGs leads to reduce the development costs of transmission system. Moreover, MGs cause a slight increase in the profitability of selling capacity to the consumers. These outcomes prove that continuing to grow the number and capacity of MGs in each area ultimately eliminate the inquiry of transmission network development and minimize the cost of capacity market.

Abstract

The plug-in electric vehicles (PEVs) including plug-in hybrid electric and all-electric vehicles will play a key role in the transportation future throughout the world. Consequently, a variety of works must be done to decrease the cost, improve the structure and increase the convenience of PEVs. This study proposed a single-phase, non-isolated and on-board battery charger with no use of any transformer which reduced the volume and weight of the system for PEVs. The main purpose is to provide an accurate control structure in order to achieve an acceptable charging in the wide range of voltage. The proposed structure is simulated by matrix laboratory (MATLAB) software. The results showed a high-power density, high efficiency and appropriate power factor from the structure of the non-isolated and single-phase charger.
