Multi-port converter with three active full bridges, two series-resonant tanks and a Multi-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load and a renewable source such as fuel cell. The converter has capabilities of bidirectional power flow in the battery and the load port. Use of series-resonance aid...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

Now a days wind power energy is playing a major role in power industry. With the raise in application of the wind power variety of topologies are emerging into picture. Within the various types of adjustable speed fixed frequency topologies DFIG is most preferred type because of its efficiency as well as capability to allow wide range of speed variance at simplified converter size. Doubly Fed I...

Congestion management (CM) is one of the most important and challenging tasks of the Independent System Operator (ISO) in the deregulated environment. Recently, Sen Transformer (ST) has emerged as an important power flow control device which has the capability of power flow control over a wide range like UPFC. This device with a conventional transformer and tap changers has the capability of bi...

This paper present a control strategy for the operation of solar energy generation integrated with grid. Boost converter is used to achieve maximum power extraction from the available solar power. The buck converter and bi-directional converter connected with common dc bus, that dc bus connected different loads with constant dc voltage. The hysteresis current controller has implemented in inver...
