I am an electrical engineer but my specialty is not grid power however my understanding is with renewable energy there are more immediate/short term problems as there are larger fluctuations with supply hence you need batteries to provide instant power.Maybe there is someone on here who can answer a query I've had in the back of my mind for some time...
As I understand it, the stability of the grid system relies on the biggest producer setting the frequency, and minor producers matching it. Is this correct? and if so, what happens to the system when there are more and more producers but putting less in each?
The grid frequency varies slightly as demand rises and falls as it is, so I'd imagine it's going to be a nightmare keeping it stable as the grid becomes more and more complex.
Any electrical engineers here? Is this a solvable problem? Is it even a problem?
Grids these days are smart and so act quickly to balance power via batteries, gas turbines and hydro. The base load provides inertia which is not present with renewables. I believe that that is where there will be problems while we slowly change our power generation.
What is electricity grid inertia?
It is vital to maintain an electrical grid's system inertia under all network conditions, no matter the source of generated power.
