Smart Plug :

With smart grid infrastructure, it will be possible to monitor electrical demand of a residential customer and control each electricity generation center for more efficient energy flow. The smallest component of the smart grid can be considered as smart homes. Better utilization of the electrical grid can be achieved through the communication of the smart home with both other customers in the grid and appliances in the house itself since generation can effectively be scheduled by having more precise demand data. 

Double input bi-directional dc-dc converter for battery/UC hybrid power sysems in elctric vehicles :

It is clear that the commercially available batteries for EVs do not meet all the expectations. In order to overcome the drawbacks mentioned in literature, the battery can be utilized in parallel with an ultra-capacitor (UC), which is an energy storage system with a higher power density when compared to the batteries. Here, the power converters play a key role to combine these two different energy storage systems. Thus, I have declared a novel topology at first as a simulation study in the peer-reviewed journals (3).

The proposed converter allows the input sources to feed the output instantaneously by enabling the power sharing between two input power sources; in the case of the fail of one of them, the other one will be able to continue the energy transfer to the output. Furthermore, if there is a requirement to transfer to energy from the input to the output, it will be possible to transfer this energy (i.e. regenerative breaking energy) to the input sources (the battery and UC) while assuring power sharing. 

In this research, a novel double input direct current converter has been proposed. Two prototypes (1 kW and 7 kW) have been prototyped after analyzing and simulating the power converter unit designed for the battery and UC hybrid system for EVs. The 1kW prototype has been tested experimentally under a standard drive cycle via a test setup (hardware-in-the-loop). The 7 kW prototype has been tested on a concept electric vehicle with an energy management strategy.
