Power distribution grids are brittle. They were not designed; they were built and added on to, with disregard for safety, security, and robustness. This has been going on for more than 100 years. In many countries, power systems just barely operate. In North America, the grid is dangerously brittle and could be damaged easily. Power plants were large, in the beginning, and either nuclear, fossil fuel, or hydroelectric. They were counted on to put power into the grids in a consistent manner, which required little fine adjustment or control. The price of electricity changed annually.
This has changed, and changed dramatically. This white paper discusses these changes and much more.
