In a microgrid, what is the most critical control objective when managing the power flow between a highly variable renewable energy source (e.g., wind turbine) and a battery energy storage system to ensure grid stability?
Question 2
Consider a Vehicle-to-Grid (V2G) system where electric vehicles (EVs) are used to provide ancillary services. If the grid experiences a sudden frequency drop, which control action would an EV's V2G inverter prioritize?
Question 3
A microgrid is operating in islanded mode with a significant penetration of solar PV. During a period of high solar irradiance and low load demand, what is the primary control challenge for the microgrid's energy management system?
Question 4
In the context of hierarchical control for microgrids, what is the primary function of the secondary control layer?
Question 5
When integrating a large-scale offshore wind farm into the main power grid, what is the most significant technical challenge related to power transmission over long distances?
