Utility grid, controller, and method for controlling the power generation in a utility grid

摘要

A utility grid is provided, the utility grid including a centralized controller; an intermittent renewable energy source for generating electrical power; at least one further power generation system; and a local controller for controlling the total power output of the intermittent renewable energy source and the at least one further power generation system, wherein the centralized controller is connected with the local controller and adapted to request a desired total power output from the local controller.

1. A utility grid serving a plurality of geographical regions, the utility grid comprising:
a plurality of intermittent renewable power sources for generating electrical power, each of the intermittent, renewable power sources being associated with at least one respective further power generation system to serve a respective geographical region of the geographical regions within the utility grid, and a local controller configured to control the total local power output of the respective intermittent renewable power source and the at least one respective further power generation system, wherein each of the local controllers comprises a forecasting device and a total local power output estimator configured to estimate a total local power output within a predetermined forecasting horizon, wherein each of the intermittent renewable power sources and the at least one respective further power generation system are of different types; and a centralized control connected with the local controllers and configured to request a respective desired total local power output from each of the local controllers, and take a countermeasure in response to an indication that at least one of the local controllers is unable to provide the respective desired local power output within the predetermined forecasting horizon.
