A microgrid controller 70 monitors the energy consumption and/or generation of equipment within a microgrid, generates data representative of consumption/generation in a prior time period and nominates a time and length of a future time period. The energy data and time period data are transferred between the controller 70 and another microgrid controller. The controller includes a processor that selects a source or sink to be used during a future time period based on its own energy/time period data and that of another controller. The future time period may be determined using nomination data, which may comprise user instructions, data representing rate of change of energy generation/consumption in a prior time period and/or data representing equipment energy prediction data. The controller may control the operation of generators and loads based on the transferred data by connecting or disconnecting equipment and varying power drawn. The energy data may include numbers representing a value or price of energy consumption or generation relative to prior consumption or generation. Reverse flow of energy through a transformer or substation (fig 1, 40) connecting a micro-grid to a distribution network (fig 1, 20) a can be minimised. |
