Description

Separation of consumers by power supply system:

– alternating current (fire pumps, emergency and general ventilation, inverter DC converters);

– direct current (refrigeration equipment, air conditioners, lighting, electric forklifts, cleaning equipment, cash settlement nodes, internal communications and security networks, fast charging stations for customers’ electric vehicles)

Consumers of an internal MicroGrid of direct current are powered by a direct current bus (DC-Bus), which in turn is connected to various independent sources of electricity: microturbine installations, an external power supply network, energy storage devices (batteries), renewable energy sources (solar panels, wind generators).

Heat supply – from the exhaust heat recovery system.

Cooling in the air conditioning system – from an absorption refrigeration machine, can be used as an option

Microgrid

• Low cost of connection
• Reduced fees for “network redundancy”
• “Seamless” reserve input, due to the use of DC bus
• Cost reduction of 1 kW / h
• Ability to use renewable energy without connecting to power grids
• Reduces DC power costs
• High quality electricity

Traditional network

• High connection cost
• Fee for “Energy Reserve”
• Large pauses during switching between operating and backup inputs in case of line accidents
• Unstable power quality
