Disclosed herein is a fundamental modeling and control method in dynamic energy conversion and transfers in complex energy systems with multiple energy sources, fuel and electric. The multi-layered modeling enables efficient and stable operation through optimized coordination of engines and electric part of a hybrid turbo-electric distribution system (TeDP). A provable coordination of power and rate of change of power interactions between the components is done at the higher-system level. Advanced nonlinear control of components is disclosed to ensure that components meet power/rate of change of power commands given by the higher level. This method is used to demonstrate, for the first time, how rotor stall and surge instabilities in engines can be eliminated by controlling the electric generators and/or storage.

Exergy/energy dynamics-based integrative modeling and control method for difficult electric aircraft missions

Embodiments of the disclosure relate to methods and systems for modeling, controlling and computer-platform implementation of a Synthetic Reserve Provisioning System (SRPS) needed to aggregate and integrate small devices closer to consumers, referred to as Distributed Energy Resources (DERs). This know-how is based on data-driven physics-based modeling and it supports the dispatch and scheduling of DERs so that they can participate in system level provision of electricity service. An SRPS generally comprises multiple levels of consumer aggregators (Synthetic Reserve Provisioning (SRP) modules) which interact by exchanging well-defined information about provable consumer characteristics and their own loading and pricing conditions. Three different SRPS designs are described. They differ with respect to implementation requirements for communications, control, technical and economic risks assumed by different SRP modules. Depending on the control and available communication architecture, it is ultimately possible to ensure DER integration at value, even with a limited number of participating devices.

Methods and systems for secure scheduling and dispatching synthetic regulation reserve from distributed energy resources

Described are concepts, systems and methods for operating microgrid systems both during normal operation conditions and during sudden, unexpected occurrences of a fault which results in a source becoming disconnected from a primary supply. This is achieved through control systems and method based upon multi-layered modeling of system controllable components and their interactions. This approach results in controllable components capable of operation in a 'plug-and-play' manner.
