Answer Question 1 Subject: Renewable Energy Systems Last Digit: 15 For Solar: 1200W, 5A, 5 strings, 4 cells in each string, the cell is (60 V, 1A) And, for Wind: 800W Need calculation, figure and proper explanation. A smart home is connected to micro grid as well as utility grid. The micro grid consists of solar and wind energy. Solar power plant meet 60% of energy demand of smart home while rest is from wind power plant in normal oper- ating condition of both power plant. The smart home rated consumption power is 2000 W (Centrifugal pump, static load each 50%). 1. Design your micro grid power generation system which can meet the power consumption requirement of the smart home.
