Voltage Quality Behaviour Of A Wind Turbine Based Remote Area Power System, Nishad Mendis, Kashem Muttaqi, Sarath Perera Nov 2012

Voltage Quality Behaviour Of A Wind Turbine Based Remote Area Power System, Nishad Mendis, Kashem Muttaqi, Sarath Perera

Associate Professor Sarath Perera

The power quality behaviour of a Remote Area Power System (RAPS) consisting of a Doubly Fed Induction Generator (DFIG), its main loads and a dummy load is presented in this paper. The dummy load is used to maintain the power balance of the system under changing wind and loading conditions. The performance of the remote area power system subject to various loading conditions has been evaluated in terms of the voltage quality, an aspect which has not received much attention in the past. The existing Distributed Generation (DG) power quality standards are taken as the basis to compare the voltage …

The application of renewable distributed generation (DG) could be considered as an alternative approach for distribution system expansion planning not only to reduce power loss and carbon emission, but also to improve system voltage profile. This paper investigates technical aspects relatedto voltage support and loss reduction in distribution systems with distributed wind and solar generation. The probabilistic wind, solar, and load models have been developed in order to address uncertain nature of wind speed, solar radiation, and load demand. Investigations have been carried out using Monte Carlo based probabilistic load flow analysis to estimate the probability distributions of system state …


Hydrogen Energy Storage For A Permanent Magnet Wind Turbine Generator Based Autonomous Hybrid Power System, Nishad Mendis, Saad Sayeef, Kashem Muttaqi, Sarath Perera Nov 2012

Hydrogen Energy Storage For A Permanent Magnet Wind Turbine Generator Based Autonomous Hybrid Power System, Nishad Mendis, Saad Sayeef, Kashem Muttaqi, Sarath Perera

Associate Professor Sarath Perera

The Performance of a novel hybrid Remote Area Power Supply (RAPS) system consisting of a Permanent Magnet Synchronous Generator (PMSG), fuel cell system, electrolyser and synchronous condenser is investigated in this paper. The fuel cell system is used to provide power during under-generation scenarios whereas the electrolyser absorbs excess power during over-generation conditions. A synchronous condenser is incorporated into the RAPS system to provide better reactive power and inertial support. Individual controllers for each system module have been developed and implemented. A control coordination methodology is established with a view to regulate the active and reactive power balance of the …
