Due to the rapid increase in global energy consumption and the diminishing of fossil fuels, the customer demand for new generation capacities and efficient energy production, delivery and utilization keeps rising. Utilizing distributed generation, renewable energy and energy storage can potentially solve such problems as energy shortage and global warming. A promising structure to interconnect these...
Increasing numbers of DER systems are being interconnected to electric power systems throughout the world. As DER technology evolves and as the impact of dispersed generation on distribution power systems becomes a growing challenge -- and a growing opportunity, countries worldwide are recognizing the economic, social, and environmental benefits of monitoring and integrating DER technology within...
Electric Utilities permitting interconnection of generation (small and/or large) on their power systems have long had standards which any entity wishing to interconnect has to meet. Recently the growing importance of distributed generation (mostly less than 10 MVA), especially using renewable sources, has prompted the creation of IEEE Std. 1547 which sets requirements and guidelines for interconnecting...
The blackout experiences have demonstrated the vulnerability of the interconnected electric power system to grid failure caused by natural disasters and unexpected phenomena. Changes in customer needs, additional stress due to liberalized electricity markets, and a high degree of dependency of today's society on sophisticated technological services also intensify the burden on traditional electric...
The paper describes problems of power system frequency control during massive penetration of DER. Main problems caused by integration of DER are considered. Model of the Baltic States power system interconnection is developed for a frequency control study. The example of the practical investigation is presented in the paper.
Interconnection equipment between distributed energy resources (DER) and the grid is typically custom designed by the distributed generation (DG) equipment manufacturer or integrated by engineering firms using subcomponents such as relays, sensors and switchgear. The DER Switch described in the paper has integrated all of the required equipment for the DER interconnection into a single package that...
