@kb1lqd shared an awesome video about #blackstarting a #PowerGrid . This is a great overview of complexity of grids. Note that #wind and #solar often FOLLOW the grid frequency so cannot SET the frequency. That’s a big problem with 100% #renewables as you need some synchronizing generators which are maybe #hydro but often steam based like #coal #gas #nuclear .
