Electricity electrical grid integration

Electrical grid integration of Generation IV nuclear energy systems in the United States... 

Countries that have large potentials of cheap fluctuating renewable electricity sources (solar or wind) that cannot be integrated into the national electricity grid (owing to problems of grid stability). 

Inverter. Development of new inverter systems for the integration of fuel cells into the electricity grid with high efficiency and in different power units (0.5-250 kW) are necessary. 

Portable generators powered by gasoline fueled internal combustion engines (ICEs) are another way that people have been making electricity mobile. The construction trades, recreational vehicle owners, festival promoters, and many others have used these ICE-powered devices to provide electricity off the electric grid. But these mobile electricity applications are marginalized by noise, localized exhaust emissions, and weak or absent integration with vehicles. 

A control subsystem is needed not only to control the fuel cell operating parameters (flow rates, temperature, humidity, etc.) but also to communicate with the load and other electrical components of the system. This is particularly critical for applications where a fuel cell operates integrated within an electrical grid. Tbe functioning of the electric and control subsystems depends on application [e.g., stand-alone, grid integrated, combined with another power source, backup power).
