As a simplified instance, try to design a system of solar panels, wind turbines, and battery storage, which gives a constant 1 GW output over the last two years at a middle european location of your choice.  Be sure to model conversion losses from/to storage.  You may omit further conversion losses downstream towards the consumer.  You may assume perfect foresight for now.

How much of each do you need?  What are the area and resource requirements?
