Technological advancement in renewable energy systems and government incentives like Feed In Tariff Program for green electricity generation is motivating utilities around the world to upgrade their existing distribution system infrastructure in order to accommodate increased wind power and photovoltaic (PV) solar power based distributed generation (DG) systems. This paper presents the effect of Distributed...
Experience with connecting farm biogas generation to rural distribution feeders in Ontario has revealed several challenges with electrical protection. The biogas projects are small (<;500kW), synchronous, farm-based, and looking for an affordable protection solution involving the use of only low-voltage equipments. The utility feeders are generally at the 8.3kV and 12.5kV voltage levels, can involve...
Experience with connecting farm biogas generation to rural distribution feeders has revealed that a particular costly barrier can be protection against unplanned islanding. When the size of the generation is small compared to the load on the feeder, the cost of anti-islanding protection is very small. However, once a certain size threshold is reached, alternative protection methods are required, and...
One of the major problems in development of distributed generation (DG) is voltage control derived from reverse power. In order that voltage variation may not degrade customer voltage supply quality, feeder voltage should be maintained within the permissible range against DG connection. To improve the voltage profile in distribution network with DG, this paper proposes several voltage control strategies...
This paper presents the application of a suitable control strategy for multibus microgrid applications. The control strategy, used with each distributed generation system in the microgrid is developed so as to combine the advantages of the current control and the voltage control strategies. The performance of the proposed application in terms of power management has been verified in simulation on...
