Method and system for optimally distributing power between a battery and a power grid
First Claim
1. A method for distributing power from a renewable power source having a variable output power over time between an energy storage device and a power grid, wherein the method is adapted to, for each one of a plurality of time slots:
- determine an output power of the power source in the respective time slot;
compare the output power of the power source to a maximum input power of the energy storage device;
determine a ratio for distributing the output power to the energy storage device or the power grid in the respective time slot based on the comparison, whereindistributing the output power to the energy storage device as a priority when the output power of the power source is below the maximum input power of the energy storage device; and
increasing the ratio for distributing the output power to the power grid and decreasing the ratio for distributing the output power to the energy storage device as the output power of the power source increases above the maximum input power of the energy storage device; and
distribute the output power from the power source to either the energy storage device or the power grid in divisions of time in the respective time slot according to the determined ratio, wherein surplus output power produced by the power source, above the maximum input power of the energy storage device, is discarded when the output power is distributed to the energy storage device,wherein when determining the ratio for distributing power, setting the ratio to one for the energy storage device, and zero for the power grid, if the power grid is not available.

Abstract
A method is provided, repeated over successive time slots, for controlling the distribution of power from a time varying renewable power source between a battery and a power grid. The method comprises comparing the maximum input power of a battery with the power output of the time varying power source and determining a ratio for distributing the power between the battery and the power grid based on the comparison. Wherein distributing the output power to the energy storage device as a priority when the output power of the power source is below the maximum input power of the energy storage device; and increasing the ratio for the grid and decreasing the ratio for the energy storage device as the output power of the power source increases above the maximum input power of the energy storage device. The surplus power produced by the power source, above the maximum input power of the energy storage device, is discarded when the output power is distributed to the energy storage device.
