2 Active energy management of smart grid 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.

3 Storage Control Sources central control system Off-grid conception for family house Wind power generation Solar collector Photovoltaic power generation Hot water storage tank AC/DC converter Off-grid energy manager Off-grid energy system (Energy storage ) DC/AC converter AC/DC bidirectional Battery DC/AC converter smart switchboard primary primary secondary secondary Smart meter Ethernet PC Visualization Wi-Fi monitor In-home display Smart phone Weather station Internet Cloud prediction of production for renewable energy sources power sensors intelligent electrical appliances

4 The Sources of electrical energy in Off-grid system ) 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, twoaxis pointing device, so-called tracker - monocrystalline solar cell technology
