Abstract:
1. A method of synchronously paralleling multiple AC power sources, the method comprising the steps of: a) providing a paralleling system comprising a main AC power source, a synchronous AC generator, a solar panel, a solar controller, said solar panel linked to said solar controller, a DC disconnect, said solar controller connected to said DC disconnect, an AC disconnect, a transfer switch, a generator controller, a load controller, said generator and load controllers connected to said synchronous AC generator, said main AC power source and said load controller connected to said transfer switch, an inverter, said inverter in communication with said AC disconnect, a load panel, said transfer switch and said inverter connected to said load panel, a system control device, said system control device in communication with said inverter, said transfer switch, said solar controller, said generator controller, and said load controller; b) measuring an electrical load by said system control device at said load panel; c) selecting an AC power source to satisfy the electrical load; d) configuring the system control device to match AC power produced by the synchronous AC generator and the renewable power source to power produced by the main AC power source; e) detecting a reverse power flow event at the AC synchronous generator; and f) throttling power produced by the renewable power source to decrease available AC power until the reverse power flow event ceases.
