SMART CITY

EXAMPLE OF A TYPICAL CASE

A 3 mn m3 real estate development project that includes residential and office buildings and infostructure

A technologically advanced innovative smart city including:

• Advanced EV charging infrastructure
• District heating and cooling
• Solar PV
• Energy storage
• Robotic parking

OUR SMART MICROGRID SOLUTION


• Modeling the smart city - Digital twin-based optimization

of total energy and carbon consumption of the building

• Developing a smart microgrid for each building that consists of:

Generation:

• Solar PV
• Trigeneration

Energy storage:

• Energy router Energy storage
• Ice storage
• Thermal storage

Microgrid

• IoT Equipment control, sensors
• Power loads, DR, emissions
• Big Data
• Analysis/visualization

Microgrid generation and energy flow control

Smart Energy Storage

Mesh optimization: Digital Twin + Machine Learning

DEMAND SIDE CONTROL AND OPTIMIZATION

• Digital twin-based model predictive control of HVAC and other equipment
• Using the building thermal capacity, refrigerator, and other equipment as energy storage
• Smart EV charging

Using the digital twin to control microgrid with the Energy Droid AI software:

• Optimize mid and low voltage grid topology cut cost by 40%
• Aggregate and control the smart city microgrids as a single portfolio of building microgrids

RESULT OF APPLYING THE SOLUTIONS WE PROVIDE

Eur 70 mn savings in caped on first stage of constructions

• Reduced heat peak load and consumption by 42%
• Reduce cooling load and consumption by 59%
• Reduce electricity peak load by 40%

Total carbon footprint reduction – 60%

• Battery energy storage come at no extra costs since they provide savings on grid connection charges
• EV charging infrastructure potential in every parking lot without increasing grid connection charge and peak load
• Aggregate generations and storage resources into a Virtual power plant
• Offer energy management and IoT based services and offer Energy as a Service to commercial and residential customers of the smart city
