Smart Grid Security and Resilience

This work presents the results of the design phase of project on integration of distributed photovoltaic power generation into the smart grid (distribution level) in the city of Parintins, which is an 17 MW isolated diesel grid located in the State of Amazon, Brazil. PV power generation in isolated systems is economically attractive, as fuel cost of 650 R$/MWh are significantly above PV generation cost. Distributed generation may be implemented without occupying valuable land on the fluvial island. A literature review provides first the general concepts of distributed generation in smart grids. In a brief description the system design, technical data, telecommunication network structure and the smart metering & billing system of the first smart grid implemented in Brazil is given. Within this R&D project financed ANEEL (electric power regulatory body) a smart grid based performance monitoring and power control for PV systems has been developed. Impacts of distributed power in the LV network have been analyzed through power flow simulation. The smart grid infrastructure will be used to assess the impact of PV generation concentrated on selected feeders and to test smart grid control strategies for distributed generation.
