MOTIVATION FOR ENERGY MANAGEMENT AND STORAGE APPLICATIONS 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 Residential Houses (new buildings and retrofit) Heat pump control (e.g. Stiebel Eltron, SG Ready) E-Vehicle Charge Wallbox (e.g. Mennekes, Schletter, ) Farms (e.g. chicken farm) Commercial Buildings (e.g. offices, hotels) 2/9/2016 SMA Smart Home 4

THE PATH TO INTELLIGENT HANDLING OF ENERGY IN RESIDENTIAL HOUSEHOLDS MONITORING ANALYSIS > 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? > 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! MANAGEMENT > 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 A well-designed Energy Management automatically adapts to the customer not vice-versa! 6
