Serial Hybrid Microgrid with PPSA-mediated interface to Genset and to Non-Dispatchable Power

摘要

A microgrid system in which power from a non-dispatchable energy source and power from a combustion-powered backup generator are both connected to the microgrid and its loads through a Power Packet Switching Architecture (PPSA) power converter. The converter provides voltage management and synchronization for both the backup generator power and also for the non-dispatchable power.

主权项

1. A microgrid, comprising:
a power-packet-switching power converter, having one port thereof connected to a microgrid power line; an engine-powered generator having a power output connected to a second port of the converter; and a non-dispatchable power source connected to a third port of the converter; wherein the engine-powered generator, when active, is allowed to vary the frequency of power at the second port over a range of at least 2% of its value, and is allowed to vary the voltage of the power output over a range of at least 10% of its value.
