Drivers for Microgrids

Microgrid risks Island modes:controlled  grid outage, power on synchronization when grid on uncontrolled  switch off grid, still power on Danger for labour Short Circuit Ground fault Power quality

How it works market Bid curve power Appliances Calculate energy need Send bid on how much energy at what price Auctioneer calculates price where supply=demand Sends back market price Appliance switched on if in the money

The cool part Bottom up approach means the appliances (you) decide if/how much external influence you accept Appliances tell how much flexibility is available at what conditions. (no surprises) No mismanagement of devices or unexpected lost comfort Works in your home just as good as for a (local) market 22

The tricky part You need a standard format for the (energy) bid Fitting it in millions of appliances means it should cost next to nothing Appliances manufacturers and energy providers need to cooperate 23 Free download
