Systems and methods of emulating power system operations. The Emulation system may include a software model of an engine driven electrical power generator, Emulation code to enable various testing of one or more power system components, and using real-world values, where applicable, to enhance the Emulation and test operation of the power system. An example method may include receiving a desired operating configuration of a proposed power system. The method may also include simulating operating data of at least one component of the power system. The method may also include emulating operations of the proposed power system using at least some actual operating data and the simulated operating data. The method may also include outputting emulated operational data for the proposed power system into an actual control and monitoring system to emulate operations of the proposed power system.
