The advances in the network technology and the emergence of the renewable energy as primary sources have changed the current view of the power system control. Smart meters will become a very important component in future power systems. In the event of an emergency the demand will play vital role in the stability of the power system. Conventionally, when a sudden generation loss occurs the generators...
In the present day situation as the energy sources are becoming extinct to generate electricity, it has become a necessity to depend on the renewable energy sources to generate the power and convert it according to the type of appliances that are in use either AC or DC loads. This paper gives brief idea on the hardware implementation of the flyback converter.
From the viewpoint of the emerging concept of smart grid, distribution network will require fast power flow solution that must be resolved as efficiently as possible. Presence of distributed generators and power electronic based compensating devices, in modern medium and low voltage distribution networks, additionaly expands requirements for performances of algorithms for power flow calculations which...
The phasor-PWM-based current source inverter (CSI) is a boost inverter. The difference between conventional CSIs and the boost inverter is that the boost ratio $(V_{\rm LLrms}/V_{\rm dc} ) $ in the boost inverter can easily be above 3.0, whereas this ratio is around 1 in conventional CSIs. In order to realize the potential capabilities of the boost inverter and to assist its penetration into renewable...
There has been growing concern about energy consumption and environmental impact of data centers. Some pioneers begin to power data centers with renewable energy to offset carbon footprint. However, it is challenging to integrate intermittent renewable energy into data center power system. Grid-tied system is widely deployed in renewable energy powered data centers. But the drawbacks (e.g. Harmonic...
The future renewable electric energy delivery and management (FREEDM) system provides a DC interface for alternative energy sources. As a result, photovoltaic (PV) energy can be easily delivered through a DC/DC converter to the FREEDM system's DC bus, without the requirement of an additional DC/AC inverter. For this PV converter, the module integrated converter (MIC) is a good candidate. In this paper,...
In this paper, a notional Future Renewable Electric Energy Delivery and Management (FREEDM) system has been developed based on a real distribution feeder. The goal is to develop a digital testbed which can be used to show capabilities of this system, and to help the development of especially the new system components and the control schemes for this system. Two digital testbeds have been developed,...
Around the world, a rapidly increasing growth of distributed energy resources (DER) based on renewable energy sources (RES) can be observed. This is due to the increase in energy demand combined with restriction in building new large scale power plants and a search for carbon-free technologies for energy production. Among the existing renewable distributed generation technologies, wind turbines (WT)...
