This paper analyzes the potential of Vehicle-to-Grid(V2G) provision of the Electric Vehicle(EV) for supporting the control of power system frequency considering the EV charging standards recently published in South Korea. As the number of EVs is expected to be rapidly increased in the near future in South Korea, its contribution on power systems operations as a kind of distributed resources is also...
As the potential economic and environmental benefits of plug-in electric vehicles (PEVs) become apparent and as strong interest develops among automakers, seamless integration of PEVs to the grid will be a critical step to encourage utility support for PEV commercialization. Technological barriers continue to fall, but taking advantage of opportunities to increase revenue and improve power system...
Disturbance location information in power system is critical information to power system operator. Fast and accurate event location estimation may help operators respond promptly to restore the system to a normal operating condition. With the help of the Internet based real-time, GPS synchronized, wide-area frequency monitoring network (FNET) , Virginia Tech has patented and implemented the event...
Frequency is an important parameter in understanding the operation of power systems. Dynamic visualization of frequency measurements provides a quick and direct way to view the state of the system. Tools are being developed to help observe frequency behavior from both simulations and real-time field measurements. Frequency replay from simulation data provides some insights of how the frequency electromechanical...
It is very important to understand system dynamics during disturbances in order to improve control measures to ensure power system security and reliability. Power system disturbances are examined in this paper based on wide-area frequency data from a nation-wide frequency monitoring network (FNET). Frequency characteristics of events in three major North America power grids are investigated. Typical...
Energy storage system (ESS) has been studied as a high-tech solution for managing power flows from wind turbine generator (WTG), and making them be competitive energy sources without putting power systems at risk. This paper illustrates possible applications of the energy storage for the wind power operating in power systems focusing on its short-duration prospective. Employing a sample power system,...
