Objectives

The SINTER (Intelligent systems to stabilize electrical grids) are integrated systems of renewable energy sources (photovoltaic and wind generators) and hydrogen-generating devices used to:

• Stabilize weak or saturated power grids
• Make renewable energy sources available to stabilize power supply even in small isolated grids

These systems have the mission of guaranteeing the quality and security of the electrical supply. Moreover they have to be able to work isolated to provide power supply to a small group of customers, industries or rural area. The main components of these systems are:

• Energy storage: hydrogen, batteries, supercapacitors and pumped-storage plant
• Generation: photovoltaic, wind or hydro generators
• Electrical grid connections: using power electronics
• Control systems
