A New Placement And Integration Method Of Upqc To Improve The Power Quality In Dg Network, Shafiuzzaman K. Khadem, Malabika Basu, Michael Conlon
A New Placement And Integration Method Of Upqc To Improve The Power Quality In Dg Network, Shafiuzzaman K. Khadem, Malabika Basu, Michael Conlon
Conference papers
A new proposal for the placement and integration of UPQC in DG connected microgrid/micro generation (μG) system has been presented here. DG converters (with storage), the load and shunt part of the UPQC will be placed at or after the PCC. The series part of the UPQC will be placed before the PCC and in series with the grid. DC link can be connected to the storage system also. Hence, it is termed UPQCμG. The advantages of the proposed UPQCμG over the normal UPQC are to compensate voltage interruptions in addition to voltage sags / swells, harmonic …
Community Microgrid Based On Micro-Wind Generation System, Lubna Mariam, Malabika Basu, Michael Conlon
Community Microgrid Based On Micro-Wind Generation System, Lubna Mariam, Malabika Basu, Michael Conlon
Conference papers
Penetration of renewable energy sources (such as solar/wind) are being explored mostly as micro power generation (μGen) or mega power plant system. In recent years, emphasis has been given on Microgrid (μGrid) systems because of their few advantages over μGen systems in terms of power quality, stability, reliability, economics etc. But the commercial installation of the μGrid system is not yet progressing significantly. This paper presents the techno-economic aspects of μGen and μGrid systems towards the development of grid connected community based μGrid (C-μGrid) system. Emphasis has been given to identify the benefits of the μGrid over the μGen system. …

In this paper, the electrical energy demand of a typical residential building has been extracted from a Virtual Environment (VE) simulation. The extracted energy demand is generated by input load demand and hourly operating information. Based on the electrical energy demand for a typical day, a building integrated photovoltaic (PV) system is then simulated in MATLAB to extract the current/voltage disturbance information into the network. Outcome of this simulation shows the voltage/current waveform along with the disturbances at different locations in the building. The city of Dublin, Ireland has been chosen as a geographical location and VE-Pro software has been …
Power Control Of Single-Stage Pv Inverter For Distribution System Volt-Var Optimization, Xiao Liu
Power Control Of Single-Stage Pv Inverter For Distribution System Volt-Var Optimization, Xiao Liu
Theses and Dissertations--Electrical and Computer Engineering
The output power variability of intermittent renewable sources can cause significant fluctuations in distribution system voltages. A local linear controller that exploits the capability of a photovoltaic inverter to provide both real and reactive power is described. This controller substitutes reactive power for real power when fluctuations in the output of the photovoltaic source are experienced. In this way, the inverter can help mitigate distribution system voltage fluctuations. In order to provide real and reactive to the grid, a three-phase grid-connected single-stage photovoltaic system with maximum power point tracking and power control is described. A method of reducing the current …
