a) What are the differences between grid-forming and grid-following DGs from the viewpoint of microgrid control Please list two grid-following DGs. b) What is the impact of system impedance on the droop control? Problem 2: Answer the following questions: a) Please describe briefly the main advantages of microgrids. b) Describe the four phases to implement a microgrid in shortly. Problem 3: A microgrid is composed of three DG units with the following droop characteristics, where the units of P and f are kW and Hz respectively. The maximal capacity of the three DG units is 300kW, 150kW and 100kW respectively. $\Delta P_1 = -100.\Delta f$ $\Delta P_2 = -200.\Delta f$ $\Delta P_3 = -300.\Delta f$ The microgrid initially is operating in primary control mode (i.e., ignore any upper-level control functions such as frequency adjustment, frequency compensation or microgrid secondary control). The initial dispatch (kW) each DG unit is given in Table 1. Suppose now the microgrid is disconnected from the grid and switched to island operation mode. Calculate the steady-state frequency and new dispatch results of the DG units based on the droop control characteristics for these three scenarios. Table 1: Initial dispatch of the units in microgrid and import power from utility grid Scenario P1(DG1):kW P2(DG2):kW P3(DG3):kW Pgrid (utility grid):kW f: Hz 1 0 0 0 300 60 2 200 0 0 100 60 3 0 150 0 50 60
