Voltage-driven Supply & Demand Management

Designing your system

  1. Determine the maximum current $I_{max}$ of the wires supporting your grid.
  2. Determine the maximum voltage drop $V_{drop}$ between two devices on your grid.
  3. Choose the level difference $V_{diff} > 2 V_{drop}$ and the top voltage $V_{top}$.
    • If you're intending to upgrade your grid to allow for higher transmitted power in the future, increasing $V_{top}$ is the easiest way to do it. Therefore it is recommended to choose a reasonable ceiling $V_{max} > V_{top}$ and select all the equipment so that it supports voltages up to $V_{max}$.
  4. Count the priority levels of sources and sinks that you want to use. A typical setup would be:
    1. (sink) Dummy load; (source) Energy harvesting
    2. (sink) Low efficiency energy storage
    3. (sink) High efficiency energy storage
    4. (source) Discharging full battery
    5. (sink) Non-critical appliances; (source) Discharging half-full battery
    6. (sink) Critical appliances; (source) Discharging near-empty battery
    7. (sink) Uninterruptable appliances; (source) Non-renewables
