test day	Nov.2016
	21	22	23	24	25	26	27	28	29	30
daily profit (10^4 DKK)	5.34	7.50	7.90	9.52	12.55	7.00	3.76	11.40	4.82	2.26
total monthly profit(10^4 DKK)			266.75		average daily profit (10^4 DKK)				8.89

Note: Take one test day for example, after implementing the proposed model series for this day, WF-ESS’s optimal offering and operating strategies can be obtained. Hence, WF-ESS’s actual daily profit means the daily profit calculated by using the obtained strategies and the realized (actual) available wind power outputs and prices data.
