Design a microgrid for a PV system rated one MW of power at 220 V, 60 Hz with all the PV strings connected to the same DC bus. The transformer data are 220/460 V, 250 kVA, and 5% reactance; and 460V/13.2 kV of 1MVA, and 10% reactance. Use the data given in Tables below. Determine the following: a. Number of modules in a string for each PV type, number of strings in an array for each PV type, number of arrays and surface area, weight and cost for each PV type. b. Boost converter and inverter specifications and the one-line diagram of this system Show the single-line diagram of the microgrid. Photovoltaic Module Data C.
