19. Consequences of growing renewables 19 Solar House hold How new customers behave New household How energy markets view all customer

20. Powermatcher gives you an alternative 20 By moving load from this period increase your use here

21. 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

22. 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

23. 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

25. Overcoming the Challenges Of Balancing Intermittent Renewables Within A Microgrid Managing the delicate balance of supply and demand while providing the necessary electrical safety functions Forecasting the supply of wind and solar How to use storage in rural vs. urban scenarios with intermittent renewable?
