A Wide Range and Precise Active and Reactive Power Flow Controller for Fuel Cell Power Conditioning Systems
… its impact and maximize feasibility of the power conditioning system in distributed generations. Because the grid voltage is constantly changing, the inverter must be able to response to it. If the inverter is unable to respond properly, then the grid voltage power comes back to the system …

Modeling of voltage source converter based HVDC transmission system in EMTP-RV
… based HVDC system is a feasible option for bulk power transmission over long or short distances and the grid integration of renewable energy sources in existing transmission and distribution systems. The main requirement in a power transmission system is the precise control of active and reactive …

Inter-area oscillation damping in large scale power systems with unified power flow controllers
"Power system oscillations occur in power networks as a result of contingencies such as faults or sudden changes in load or generation. They are detrimental to the operation of the system since they affect system stability and the optimal power flow through it. These oscillations do not usually …
