MOTIVATION FOR ENERGY MANAGEMENT AND STORAGE APPLICATIONS

4

Criteria for beneficial Energy Management

and Storage Applications

Examples for Energy Management

and Storage Applications

• Getting more control over the electricity bill

• People like the idea to be more independent from local power providers

• In many markets PV electricity costs are already lower than grid electricity costs (Grid parity)

• Integration of e-vehicles and HVAC components promises synergies

• Cancellation/reduction of Feed-In tariffs

• Power peak shaving to reduce maximum reverse power flow in distribution grid

Farms (e.g. chicken farm)

E-Vehicle Charge Wallbox (e.g. Mennekes, Schletter, …)

Heat pump control

(e.g. Stiebel Eltron, SG Ready)

Commercial Buildings (e.g. offices, hotels)

Residential Houses

(new buildings and retrofit)

THE PATH TO INTELLIGENT HANDLING OF ENERGY IN RESIDENTIAL HOUSEHOLDS

> … How much energy is consumed in my house?

> … What consumption do my appliances have?

> … How often do I use my appliances?

> … How much energy is generated by my PV plant?

> … What was my PV self consumption rate in the last days/months?

6

> … Appliances run, when energy is lowest cost (economical focus)

> … Appliances run, when there is enough sunshine (ecological focus)

> … Automated appliance control without loss of comfort

> … Optimized usage of energy storage systems (battery storage, heat pump)

> … Automatic adjustment to usage changes through self-learning system

> … This appliance has the highest usage of energy!

> … This appliance uses too much energy!

> … For these appliances the stand-by mode should be activated!

> … This size of PV plant ideally covers my individual energy consumption!

> … This energy tariff is the best fit for my requirements!

Sunny Portal provides a clear and yet comprehensive information and control interface.

The current status screen shows:

• PV power generation

• Household consumption

• Grid feed-in power

• Purchased power from grid

• Battery charge/discharge (in case of battery systems)

In addition, the system operator sees the PV generation forecast over the next hours as well as recommended actions.

For loads/appliances with energy management control, the current operation schedule is shown

> „The EEBus concept is not a new bus system. It is much more a middleware for the universal translators

between existing field bus systems.„...“Via the networking technology EEBus, energy providers and

electronic devices can communicate with each other and in this way optimally control consumption” (Source Homepage EEBus)

> SMA is member of the EEBus group and

collaborates activly on the standardization

> EEBus allows a transmission mode and

protocol independent communication between

different devices

> Aim is, to integrate EEBus compatible devices

into the energy managament of the Smart
