A METHOD FOR CONTROLLING ENERGY CONTENT AND POWER FLOW IN A LOCAL POWER GRID

摘要

The present disclosure relates to a method, performed in a control unit, for controlling energy content and power flow in a local power grid at least intermittently connected to an external power grid. The method comprises obtaining (S11) information regarding: power consumptions in controllable loads and non-controllable loads influencing energy content and power flow in the local power grid, current energy content in energy storage accessible to the local power grid, and market prices for energy related commodities and power related commodities available in the external power grid. The method further comprises: calculating (S13) energy content and power flow forecasts within the local power grid based on the obtained information, optimizing (S15) the energy content and power flow within the local power grid based on the forecasts, and applying (S16) the optimized energy content and power flow within the local power grid during a predetermined time interval.
