specific requirements
■ autonomous running with independence on the delivering of
energy from external power grids,
■ operation of active distribution grid with well-balanced
between production and consumption of electric energy,
■ energy storage possibility,
■ using mainly renewable sources of electric energy,
nontraditional character of load,
■ new conception of protection with bi-directional power flow
■ active energy management system with supporting of
methods of artificial intelligence.

The Sources of electrical energy in Off-grid system
1) wind power plant with apparent power of 8
kV∙A. Wind power plant consists of 20 poles
synchronous generator with permanent
magnets and autonomic control system.
Off-grid system disposes 2 strings of
photovoltaic power plants.
2) photovoltaic power plants with installed power
2 kWp, fixed installation - polycrystalline solar
technology
3) photovoltaic power plants with installed power 2 kWp, two-
axis pointing device, so-called tracker - monocrystalline
solar cell technology
